Description

System message transmission method, device and system

Technical field

The present disclosure relates to the field of wireless communication technologies, and in particular, to a method, device, and system for transmitting system messages.

Background technique

In a conventional communication system, such as a Long Term Evolution (LTE) system, most system messages, such as a Master Information Block (MIB) message and a part transmitted in a broadcast channel, are used. System Information Blocks messages are sent periodically.

In the related LTE system, in order to minimize the resource occupation of periodic messages, the system message is usually divided into different parts for transmission. Illustratively, a larger part of system messages are placed on channels or system resources that do not need to be periodically transmitted. Intra-transmission, placing a small portion of system messages on a periodic transmission channel like a broadcast channel for transmission. A part of the above-mentioned system message is defined as a minimum message, and the priority of the minimum message is high. The manner in which the minimum message is sent in the related LTE system is: the part of the system that carries the system message in the broadcast channel is the smallest. The message is sent, and the part of the minimum message sent by the broadcast channel does not include the parameters required for the terminal device to perform the uplink transmission. The base station needs to notify the terminal device of the resources in the physical broadcast channel (Physical Broadcast Channel, PBCH for short). Obtaining the remaining minimum message in the location, that is, the parameters required for the terminal device to perform the uplink transmission need to be transmitted in the remaining minimum message, and the terminal device can perform the uplink transmission after receiving the remaining minimum message, thereby The delay and overhead of the uplink transmission of the terminal device are relatively large. In order to improve the utilization of resources, the new generation of mobile communication system (New Radio, NR for short) also requires that the system messages periodically sent in the system occupy less resources as much as possible. Therefore, it has been proposed in the relevant LTE system. The segmentation method is applied to a new generation mobile communication system to transmit system messages.

However, if the segmentation mode in the related LTE system is applied to the next-generation mobile communication system, the terminal device needs to perform uplink transmission after receiving the remaining minimum message, so that the delay and overhead of the uplink transmission of the terminal device are caused. In addition, because the segmentation mode in the LTE system is relatively fixed, it is only applicable to a specific application scenario, that is, the utility and flexibility of transmitting the system message by using the segmentation mode are poor.

Summary of the invention

detailed description

The embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments in the present application may be arbitrarily combined with each other.

The steps illustrated in the flowchart of the figures may be executed in a computer system such as a set of computer executable instructions. Also, although logical sequences are shown in the flowcharts, in some cases the steps shown or described may be performed in a different order than the ones described herein.

Before describing the transmission method of the system message provided by the embodiment of the present disclosure, the manner of dividing the minimum message in the sending system message in the related LTE system is briefly described. As shown in FIG. 1 , it is a flowchart of sending a system message in the related LTE system. The system message transmitted in 1 is the smallest message with higher priority. The process shown in Figure 1 includes the following steps, namely steps 1 to 4:

Step 1: The base station sends a partial minimum message by using a broadcast channel, where the partial minimum message does not include an uplink transmission parameter; correspondingly, the terminal device receives the partial minimum message;

Step 2: The base station notifies the terminal device to receive the resource of the remaining minimum message in the PBCH;

Step 3: The terminal device receives the remaining minimum message on the resource notified by the base station, where the remaining minimum message includes an uplink transmission parameter.

Step 4: The terminal device sends the uplink data according to the uplink transmission parameter in the remaining minimum message that has been received.

It can be seen from the flow shown in FIG. 1 that the terminal device needs to obtain the uplink transmission parameter after receiving the remaining minimum message, and then the uplink signal can be sent according to the uplink transmission parameter, so that the terminal device delays the uplink transmission. And the cost is relatively large.

The following is a detailed description of the technical solutions of the present disclosure. The entities in the following embodiments of the present disclosure include the base station and the terminal device. The base station may include: a base station (Base Station, BS for short), and an evolved type. The base station (evolved Node B, hereinafter referred to as eNB), and the terminal device is, for example, a user equipment (User Equipment, UE for short), and may include, for example, a personal computer (Personal Computer, PC for short), a smart phone, and a tablet computer. And Personal Digital Assistant (PDA). The present disclosure provides that the following exemplary embodiments may be combined with each other, and the same or similar concepts or processes may not be described in some embodiments.

First embodiment

FIG. 2 is a flowchart of a method for transmitting a system message according to a first embodiment of the present disclosure. The system message transmission method provided in this embodiment is applicable to the case of transmitting system messages in a new generation mobile communication system, and the method may be performed by a system message transmission device, and the system message transmission device is combined by hardware and software. to realise, The device can be integrated into the processor of the base station for use by the processor. As shown in FIG. 2, the method in this embodiment may include:

S110. The base station sends a first system message to the terminal device by using a broadcast channel, where the first system message includes a receiving parameter and indication information of the second system message, where the indication information is set to indicate whether the first system message includes an uplink transmission parameter.

In the embodiment of the present disclosure, a method is provided for a base station to send a system message to a terminal device in its coverage area. Within the coverage of the base station, the system has multiple cells, and each cell has multiple terminal devices. The system message to be sent by the base station in the embodiment of the present disclosure includes at least the foregoing first system message and the second system message, where the first system message and the second system message are messages with higher priority in the system message, which can be understood as, One system message is the partial minimum message in FIG. 1, and the second system message is the remaining minimum message in FIG. The uplink transmission parameters in the embodiment of the present disclosure include, for example, resource configuration parameters such as resources, power, and code channels required for the terminal device to perform uplink transmission. For example, the uplink transmission is an uplink random access signal, and the uplink transmission parameter may include a preamble index. Time-frequency resources, power configuration and other parameters of the random access signal.

In the embodiment of the present disclosure, the base station may send the first system message and the second system message in a plurality of times, and send the first system message by using a broadcast channel, where the first system message includes a receiving parameter of the second system message, and the receiving parameter is set. In order to indicate on which resources the base station subsequently sends the second system message, and on the terminal device side, after receiving the first system message, the receiving parameter of the second system message may be acquired, and according to the receiving parameter, it is known on which resources to receive the first system message. Two system messages.

In the related LTE system, the uplink signal is not included in the minimum message transmitted first, and therefore, the terminal device can transmit the uplink signal after receiving the remaining minimum message (ie, the second system message). In contrast, the first system message in the embodiment of the present disclosure further includes indication information. When the indication information indicates that the first system message includes an uplink transmission parameter, the terminal device may receive the first system message. The uplink signal is transmitted, and the delay and the overhead of the uplink transmission performed by the terminal device are reduced. When the indication information indicates that the first system message does not include the uplink transmission parameter, the terminal needs to transmit the uplink transmission parameter after the base station sends the uplink transmission parameter, and does not include In the case of uplink transmission parameters, due to the transmission characteristics of the new generation mobile communication system, it has higher practicability in some application scenarios, and various cases of additional information are described in detail later.

S120. The base station sends the second system message to the terminal device according to the receiving parameter of the second system message.

In the embodiment of the present disclosure, the base station may carry the receiving parameter of the second system message in the first system message, so that both the base station and the terminal device can know on which resources the second system message should be sent, that is, the second system message. The receiving parameter is set to indicate the resource location at which the second system message is sent. For example, if the indication information indicates that the first system message includes an uplink transmission parameter, the first system message further includes an uplink transmission parameter, and the terminal device may perform the uplink transmission parameter after receiving the first system message. For example, if the indication information indicates that the uplink transmission parameter is not included in the first system message, the uplink transmission parameter may be carried in the second system message, and the terminal device receives the second system message. The uplink transmission may be performed; in the above two cases, the time when the base station sends the second system message is different from the content in the second system message.

In an actual application, the first system message and the second system message may all include an uplink transmission parameter. At this time, the uplink transmission parameter in the first system message is a subset of the uplink transmission parameter set in the second system message.

It should be noted that the receiving parameter of the second system message included in the first system message of the embodiment of the present disclosure may be, for example, a control part of the second system message, or a resource part of the control part and the data part, and the receiving parameter may be All resource locations of the second system message are described, and some resource locations describing the second system message may be described. Some resource locations not described may be predefined, or may be obtained by the terminal device through blind detection. For example, in a system message sent on a time domain resource and a frequency domain resource, only a part of the resource location is described, and the resource location of the complete system message can be calculated. Therefore, in many application scenarios, the foregoing receiving parameter is only described. The partial resource location of the second system message enables the base station and the terminal device to know the specific resource location for sending the second system message, that is, the base station and the terminal device can send and receive the second system message on the same resource location. The second system message form is more diverse, and may be information in an LTE-like SIB, or a system message transmitted in a data sharing channel, or a system message transmitted in a second PBCH other than the PBCH.

In the method for transmitting a system message according to the embodiment of the present disclosure, the base station sends a first system message to the terminal device by using a broadcast channel, where the first system message includes a receiving parameter and indication information of the second system message, and the indication information is set as an indication. Whether the uplink transmission parameter is included in the first system message, and then the base station may send the second system message to the terminal device according to the receiving parameter of the second system message. In the method provided in this embodiment, the system message is divided into at least two. Partly, and by reasonably designing the content carried in the first system message, sending the second system message in a manner suitable for the current application scenario, and solving the problem that when the segmentation mode in the related LTE system is applied to the next generation mobile communication system, The terminal device needs to receive the remaining minimum message before performing the uplink transmission, which causes the delay and overhead of the uplink transmission of the terminal device. In addition, the transmission system is also solved because the segmentation mode in the LTE system is relatively fixed. The practicality and flexibility of the message is poor.

Optionally, in the embodiment of the present disclosure, the foregoing indication that the indication information may indicate different content, if the indication information is set to indicate that the first system message does not include an uplink parameter, implicitly implies that the terminal needs to receive the first After the second system message is sent, the uplink transmission may be performed; if the indication information is set to indicate that the first system message includes an uplink transmission parameter, the indication information may further be extended to indicate which uplink is included in the first system message. The transmission parameter, that is, the indication information may also be set to indicate different uplink transmission parameter configurations. For example, the configurations of three different uplink configuration parameters may be respectively represented by 01, 10, and 11 of the 2 bits.

Optionally, FIG. 3 is a flowchart of another method for transmitting a system message according to the first embodiment of the present disclosure. The foregoing has been described above. When the indication information is set to indicate that the first system message includes the uplink transmission parameter, the first system message further includes the uplink transmission parameter. Before the S120, the embodiment may further include:

S111. The base station receives an uplink signal sent by the first terminal device according to the uplink transmission parameter.

The implementation of S120 in this embodiment is: the base station sends the second system message to the first terminal device on the basic time domain resource unit that carries the second system message according to the receiving parameter of the second system message.

The method provided in this embodiment may further include: after S111:

S112. The base station determines, according to resources of the uplink signal, a resource that is set to send the second system message; the second system The resources of the unified message include one or more of an antenna port and a beam index.

As shown in FIG. 4, a schematic diagram of a system message transmission in the method for transmitting a system message provided in the embodiment shown in FIG. 3, as shown in FIG. 4, in the manner of sending a system message provided in this embodiment, The base station sends the parameter that is sent in the remaining minimum message, which is set in the remaining minimum message, to the minimum message in the broadcast channel, that is, the first system message carries the uplink transmission parameter, and the terminal device receives the first After the system message, the uplink transmission can be attempted, and the uplink transmission is likely to be the transmission of the random access signal. In the case of multi-beam transmission and reception, the uplink transmission is, for example, a transmission of a random access signal, and the uplink transmission and the downlink beam have a mapping relationship, so that the base station can determine the downlink relationship with the uplink signal by receiving the uplink signal. The beam, that is, which beam is a suitable downlink beam, is used to facilitate the use of the appropriate downlink beam when transmitting the second system message. When the appropriate downlink beam is selected, the second system message can use only the determined downlink beam. Sending and receiving are performed; optionally, the second system message may be transmitted and received using a partial downlink beam adjacent to the determined downlink beam in addition to using the determined downlink beam transmission to improve the probability and stability of beam reception. Correspondingly, the terminal device can receive the second system message only on the determined downlink beam or the peripheral part downlink beam, and the receiving parameter of the second system message is also sent in the first system message in the broadcast channel, when the terminal device After receiving the second system message, it can be based on the second system Uplink transmission of other parameters in the message transmitted uplink signal. Since the second system message can clarify the appropriate downlink beam through the mapping relationship, multi-beam transmission is not needed in the resource arrangement, and the resource can be packaged and transmitted with the normal data, that is, the control signal can be utilized. And the basic time domain resource unit of the data signal is sent, where the length of the basic time domain unit is greater than or equal to 7 symbols; optionally, the basic time domain resource unit in the embodiment of the disclosure may also be an independent transport block. In this case, the length of the basic time domain resource unit is less than 7 symbols, and the symbols described in the embodiments of the present disclosure are all Orthogonal Frequency Division Multiplexing (OFDM) symbols.

Optionally, FIG. 5 is a flowchart of still another method for transmitting a system message according to the first embodiment of the present disclosure. The foregoing description has been made that when the indication information is set to indicate that the first system message does not include the uplink transmission parameter, the manner in which the base station sends the second system message is different from the embodiment shown in FIG. 3, that is, the implementation manner of S120 in this embodiment may be The base station sends a second system message to the terminal device on the N basic time domain resource units carrying the second system message according to the receiving parameter of the second system message; where N is a positive integer greater than 1.

As shown in FIG. 6, a schematic diagram of a system message transmission in the method for transmitting a system message provided in the embodiment shown in FIG. 5, as shown in FIG. 6, in the manner of sending a system message provided in this embodiment, The indication information in the first system message sent by the base station is set to indicate that the uplink transmission parameter is not included in the first system message, and the difference from the transmission diagram shown in FIG. 4 is whether the terminal device can receive the second system message. The uplink signal can be sent according to the uplink transmission parameter, and whether the base station can determine the downlink beam that is set to send the second system message according to the uplink signal. Obviously, in the transmission mode shown in FIG. 6, the terminal device needs to receive the second signal. After the system message is sent, the uplink signal can be sent. That is, the base station cannot determine the downlink beam set to send the second system message by using the uplink signal. Therefore, in order to enable the terminal equipment in the coverage of the base station to receive the uplink transmission parameter, the base station can Multiple antenna ports or multiple beam indices can be used to target terminal devices on N basic time domain resource units The message sent to the second system, i.e., the second System messages need to be sent using multiple beams to cover the terminal devices in different locations. In this embodiment, the basic time domain resource unit is usually an independent transport block, and the length of the basic time domain resource unit is less than 7 symbols.

Optionally, FIG. 7 is a flowchart of still another method for transmitting a system message according to the first embodiment of the present disclosure. On the basis of the embodiment shown in FIG. 1 , the method provided in this embodiment may further include:

S100. The base station determines a load status of a target cell of the system message to be sent.

S101. The base station adds, according to a load status of the target cell, indication information that is set to indicate different content in the first system message.

In the embodiment of the present disclosure, the base station may selectively use the transmission mode shown in FIG. 4 and FIG. 5 for the load degree of the cell in the coverage area. In an actual application, the manner in which the base station adds the indication information may be: When the load state of the target cell is less than the preset load threshold, the first system message is added with the indication information indicating that the first system message includes the uplink transmission parameter; when the base station's load state is greater than or equal to the preset load threshold. And adding, in the first system message, indication information that is set to indicate that the first system message does not include an uplink transmission parameter.

The embodiments shown in FIG. 3 and FIG. 4 can determine the appropriate downlink beam by using the uplink signal, and the second system message does not need to undergo beam scanning or participates in transmitting a very small beam, and consumes less resources, which is suitable for the cell load. A lighter scenario; the sending of the second system message in the embodiment shown in FIG. 5 and FIG. 6 needs to undergo a beam scanning process, which consumes more resources and is suitable for a case where the cell load is relatively heavy, so that even if beam scanning is required, Due to the large distribution density of the terminal devices and the uniform distribution, each scanning beam has a greater chance of covering the terminal device, and the corresponding efficiency is not low.

It should be noted that, in combination with the advantages and disadvantages of the transmission modes shown in FIG. 4 and FIG. 6 above, it can be seen that when the cell load is both lighter and heavier, the embodiment shown in FIG. 3 and FIG. 5 are The method of the embodiment needs to coexist in the same system, and can select different segmentation and transmission modes of system messages according to different scenarios, which is beneficial to improve overall resource utilization efficiency under different load conditions. The embodiment of the present disclosure is directed to the foregoing problem, and the first system message carries the indication information that is set to indicate whether the first system message includes an uplink transmission parameter, and solves the problem that the transmission modes described in FIG. 4 and FIG. 6 coexist, that is, when the terminal When the device receives the first system message, it can determine whether there is an uplink transmission parameter in the broadcast channel, thereby selecting a different processing manner. FIG. 8 is a schematic structural diagram of a first system message in a method for transmitting a system message according to an embodiment of the present invention. The first system message shown in FIG. 8 is transmitted in a broadcast channel, and the first system message shown in FIG. The information indicates whether the uplink transmission parameter is included. If the indication includes, the bearer of the corresponding uplink transmission parameter is followed by the indication information. If the indication is not included, the subsequent location is null (NULL) or carries other messages.

Optionally, in the embodiment of the present disclosure, the second system message may include the admission control information. In the embodiment shown in FIG. 3 and FIG. 4, the base station receives the first one because the first system message includes an uplink transmission parameter. After the uplink signal sent by the terminal device, the second system message carrying the admission control information is sent to the first terminal device; in the embodiment shown in FIG. 5 and FIG. 6, the base system does not include the uplink transmission parameter, and the base station After transmitting the first system message, the second system message carrying the admission control information is directly sent to the terminal device.

Optionally, in the embodiment of the present disclosure, the setting that is carried in the first system message to indicate different content may be adopted. Indicates the manner of the information to indicate whether the first system message carries an uplink transmission parameter. On the one hand, the typical carrying method is to carry directly, that is, to include indication information in a manner displayed in the first system message, for example, using bit 0 to indicate that there is no uplink transmission parameter, and bit 1 to indicate that there is an uplink transmission parameter; The indication information may be further extended, for example, by using a 1-bit simple indication, such as using 2 bits of 00 to indicate that the first system message does not include an uplink parameter or instructing the UE to receive the second system message; and indicating with 01, 10, and 11 The first system message includes uplink transmission parameters, and 01, 10, and 11 may respectively represent three different uplink configuration parameters, and further extension bits are also allowed. On the other hand, it is also possible to use an implicit manner to indicate that the indication information is not carried in the first system message, but the purpose of the indication information is achieved by indirect means, that is, the indication information may pass one of the following or The multiple forms represent: the modulation mode, the coding mode, and the occupied bandwidth length of the first system message, and when the content of the indication form of the indication information is A, the indication information is set to indicate that the first system message includes an uplink transmission parameter, when the indication is When the content of the representation of the information is B, the indication information is set to indicate that the first system message does not include an uplink transmission parameter, wherein contents in the representations corresponding to A and B are different; for example, when the first system message When the modulation or coding mode is A, the indication information indicates that the first system message includes an uplink transmission parameter. When the first system message modulation or coding mode is B, the indication information indicates that the first system message does not include an uplink transmission parameter, and A and B correspond to Modulation and/or coding in different ways; for example, indicating the occupied bandwidth of the first system message When the first system message occupation bandwidth is A, the indication information indicates that the first system message includes an uplink transmission parameter, and when the first system message occupation bandwidth is B, the indication information indicates that the first system message does not include an uplink transmission parameter, A The occupied bandwidth corresponding to B is different. When the terminal identifies the modulation mode, the coding mode, or the occupied bandwidth length of the first system message in the decoding process, the terminal can fully obtain the indication information including whether the uplink transmission parameter is included.

In the embodiment of the present disclosure, the method for carrying the indication message indicating the different content is carried in the first system message, so that the second system message is sent in different manners in different application scenarios, and the terminal device sends the uplink. Different timings of signals, because different ways of dividing system messages will bring different resource bearers and transmission modes, the practice of using beam transmission and reception is introduced in the new generation mobile communication system, combined with beam correlation processing, system messages. The transmission and resource bearer modes of each part have special characteristics. In addition, by designing unified signaling between different split modes, different split modes can be implemented or coexist in one system, that is, suitable for use in different application scenarios. In addition, since the receiving parameters of the second system message of the terminal device are generally notified in the PBCH in the related art, if there are not enough resources in the PBCH to notify the terminal device on which resources to receive the second system message, the present method may be used. The second system is sent in various manners provided by the disclosed embodiments Receiver parameters.

Embodiments of the present disclosure provide a storage medium. In an embodiment of the present disclosure, the storage medium may be configured to be stored in a base station, the storage medium being configured to perform the method steps in any of the embodiments illustrated in FIGS. 2, 3, 5, and 7.

FIG. 9 is a flowchart of still another method for transmitting a system message according to the first embodiment of the present disclosure. The system message transmission method provided in this embodiment is applicable to the case of transmitting system messages in a new generation mobile communication system, and the method may be performed by a system message transmission device, and the system message transmission device is combined by hardware and software. to realise, The device can be integrated into the processor of the terminal device for use by the processor. As shown in FIG. 9, the method in this embodiment may include:

S210. The terminal device receives, by using a broadcast channel, a first system message that is sent by the base station, where the first system message includes a receiving parameter and indication information of the second system message, where the indication information is set to indicate whether the first system message includes an uplink transmission. parameter.

In the embodiment of the present disclosure, a manner is provided for the terminal device to receive the system message sent by the base station, and within the coverage of the base station, there are multiple cells, and each cell has multiple terminal devices. The system message to be received by the terminal device in the embodiment of the present disclosure includes at least the foregoing first system message and the second system message, where the first system message and the second system message are messages with higher priority in the system message, which can be understood as: The first system message is the partial minimum message in FIG. 1, and the second system message is the remaining minimum message in FIG. The uplink transmission parameters in the embodiment of the present disclosure include, for example, resource configuration parameters such as resources, power, and code channels required for the terminal device to perform uplink transmission. For example, the uplink transmission is an uplink random access signal, and the uplink transmission parameter may include a preamble index. Time-frequency resources, power configuration and other parameters of the random access signal.

In the embodiment of the present disclosure, the terminal device may receive the first system message and the second system message in a divided manner, and receive the first system message by using the broadcast channel, where the first system message includes the receiving parameter of the second system message. The receiving parameter is set to indicate on which resources the base station subsequently sends the second system message, and the terminal device can obtain the receiving parameter of the second system message after receiving the first system message, and learn which resources are obtained according to the receiving parameter. Receive a second system message.

In the related LTE system, the uplink signal is not included in the minimum message transmitted first, and therefore, the terminal device can transmit the uplink signal after receiving the remaining minimum message (ie, the second system message). In contrast, the first system message in the embodiment of the present disclosure further includes indication information. When the indication information indicates that the first system message includes an uplink transmission parameter, the terminal device may receive the first system message. The uplink signal is transmitted, and the delay and the overhead of the uplink transmission performed by the terminal device are reduced. When the indication information indicates that the first system message includes the uplink transmission parameter, the terminal needs to transmit the uplink transmission parameter after the base station sends the uplink transmission parameter, and does not include the uplink. In the case of transmission parameters, due to the transmission characteristics of the new generation mobile communication system, it has higher practicability in some application scenarios, and various cases of additional information are described in detail later.

S220. The terminal device receives the second system message sent by the base station according to the receiving parameter of the second system message.

In the embodiment of the present disclosure, the first system message received by the terminal device carries the receiving parameter of the second system message, so both the base station and the terminal device can know on which resources the second system message should be sent, that is, the second system. The receiving parameter of the message is set to indicate the resource location at which the second system message is sent. For example, if the indication information indicates that the first system message includes an uplink transmission parameter, the first system message further includes an uplink transmission parameter, and the terminal device may perform the uplink transmission parameter after receiving the first system message. For example, if the indication information indicates that the uplink transmission parameter is not included in the first system message, the uplink transmission parameter may be carried in the second system message, and the terminal device receives the second system message. The uplink transmission may be performed; in the above two cases, the time when the terminal device receives the second system message is different from the content in the second system message.

In an actual application, the first system message and the second system message may all include an uplink transmission parameter. The uplink transmission parameter in a system message is a subset of the set of uplink transmission parameters in the second system message.

It should be noted that the receiving parameter of the second system message included in the first system message of the embodiment of the present disclosure may be, for example, a control part or a control part of the second system message and a resource location of the data part, and the receiving parameter may be a description. The entire resource location of the second system message may also be a partial resource location describing the second system message. The undescribed part of the resource location may be predefined, or may be obtained by the terminal device by blind detection. For example, in a system message sent on a time domain resource and a frequency domain resource, only a part of the resource location is described, and the resource location of the complete system message can be calculated. Therefore, in many application scenarios, the foregoing receiving parameter is only described. The partial resource location of the second system message enables the base station and the terminal device to know the specific resource location for sending the second system message, that is, the base station and the terminal device can send and receive the second system message on the same resource location. The second system message form is more diverse, and may be information in an LTE-like SIB, or a system message transmitted in a data sharing channel, or a system message transmitted in a second PBCH other than the PBCH.

The method for transmitting a system message according to the embodiment of the present disclosure, the terminal device receives the first system message sent by the base station by using a broadcast channel, where the first system message includes a receiving parameter and indication information of the second system message, and the indication information is set to Indicates whether the first system message includes the indication information of the uplink transmission parameter, and then the terminal device may receive the second system message sent by the base station according to the receiving parameter of the second system message. In the method provided in this embodiment, the system is adopted. The message is divided into at least two parts, and the second system message is sent in a manner suitable for the current application scenario by reasonably designing the content carried in the first system message, thereby solving the problem that the segmentation mode in the related LTE system is applied to the next generation mobile communication. In the system, the terminal device needs to receive the remaining minimum message before performing the uplink transmission, which causes the delay and overhead of the uplink transmission of the terminal device. In addition, the segmentation mode in the LTE system is relatively fixed. , which leads to the practicality of sending system messages and The problem of poor activity.

Optionally, FIG. 10 is a flowchart of a method for transmitting a system message according to the first embodiment of the present disclosure. The foregoing has been described above, when the indication information is set to indicate that the first system message includes the uplink transmission parameter, the first system message further includes the uplink transmission parameter, and the S220 in this embodiment may further include:

S211. The terminal device sends an uplink signal to the base station according to the uplink transmission parameter.

The implementation of S220 in this embodiment is: the terminal device receives the second system message sent by the base station on the basic time domain resource unit that carries the second system message according to the receiving parameter of the second system message.

In this embodiment, when the second system message includes the uplink transmission parameter, the S220 of the embodiment may further include: S230, the terminal device sends another uplink signal according to the uplink transmission parameter in the second system message.

Referring to the transmission diagram shown in FIG. 4, in the manner of sending a system message provided in this embodiment, A system message carries an uplink transmission parameter, and after receiving the first system message, the terminal device may try to perform uplink transmission, and the uplink transmission is likely to be a random access signal transmission. In the case of multi-beam transmission and reception, the uplink transmission is, for example, a transmission of a random access signal, and the uplink transmission and the downlink beam have a mapping relationship, so that the base station can determine the downlink relationship with the uplink signal by receiving the uplink signal. The beam, that is, which beam is a suitable downlink beam, is used to facilitate the use of the appropriate downlink beam when transmitting the second system message. When the appropriate downlink beam is selected, the second system message can use only the determined downlink beam. Sending and receiving are performed; optionally, the second system message may be transmitted and received using a partial downlink beam adjacent to the determined downlink beam in addition to using the determined downlink beam transmission to improve the probability and stability of beam reception. Accordingly, the terminal device may receive the second system message only on the determined downlink beam or the peripheral portion downlink beam, and the receiving parameter of the second system message is also sent in the first system message in the broadcast channel. Since the second system message can clarify the appropriate downlink beam through the mapping relationship, multi-beam transmission is not needed in the resource arrangement, and the resource can be packaged and transmitted with the normal data, that is, the control signal can be utilized. And transmitting the basic time domain resource unit of the data signal, where the length of the basic time domain unit is greater than or equal to 7 symbols; optionally, the basic time domain resource unit may also be an independent transport block, and the basic time domain is The length of the resource unit is less than 7 symbols.

Optionally, FIG. 11 is a flowchart of still another method for transmitting a system message according to the first embodiment of the present disclosure.

The terminal device receives, according to the receiving parameter of the second system message, the second system message sent by the base station on the N basic time domain resource units that carry the second system message; where N is a positive integer greater than 1.

In this embodiment, when the second system message includes the uplink transmission parameter, the S220 of the embodiment may further include: S230, the terminal device sends the uplink signal according to the uplink transmission parameter in the second system message.

Referring to the transmission diagram shown in FIG. 6 , in the manner of sending the system message provided by the embodiment, the indication information in the first system message received by the terminal device is set to indicate that the first system message does not include the uplink transmission. The difference between the parameter and the transmission diagram shown in FIG. 4 is whether the terminal device can send an uplink signal according to the uplink transmission parameter before receiving the second system message, and whether the base station can determine to set the transmission according to the uplink signal. The downlink beam of the second system message. Obviously, in the transmission mode shown in FIG. 6, the terminal device needs to send the uplink signal after receiving the second system message, that is, the base station cannot determine the setting to send the second by using the uplink signal. The downlink beam of the system message. Therefore, in order to enable the terminal equipment in the coverage of the base station to receive the uplink transmission parameter, the base station may adopt multiple antenna ports or multiple beam indexes to the terminal device on the N basic time domain resource units. Sending the second system message, that is, the second system message needs to be sent by using multiple beams. To cover the terminal devices in different locations; correspondingly, the terminal device may use multiple antenna ports or multiple beam indexes to receive the second system message sent by the base station on the N basic time domain resource units. In this embodiment, the basic time domain resource unit is usually an independent transport block, and the length of the basic time domain resource unit is less than 7 symbols.

It should be noted that, in the embodiment of the present disclosure, if the indication information in the first system message is set to indicate that the first system message includes an uplink transmission parameter, the base station confirms the specific content indicated by the indication information according to the cell load status.

After the uplink signal is sent according to the uplink transmission parameter, the second system message that is sent by the base station and carries the admission control information is received. In the embodiment shown in FIG. 11, the terminal device is in the first system message. After receiving the first system message, the second system message that is sent by the base station and carries the admission control information may be received.

Optionally, in the embodiment of the present disclosure, the manner in which the first system message carries the indication information indicating the different content is used to indicate whether the first system message carries the uplink transmission parameter. On the one hand, the typical carrying method is to carry directly, that is, to include indication information in a manner displayed in the first system message, for example, using bit 0 to indicate that there is no uplink transmission parameter, and bit 1 to indicate that there is an uplink transmission parameter; The indication information may be further extended, for example, by using a 1-bit simple indication, such as using 2 bits of 00 to indicate that the first system message does not include an uplink parameter or instructing the UE to receive the second system message; and indicating with 01, 10, and 11 The first system message includes uplink transmission parameters, and 01, 10, and 11 may respectively represent three different uplink configuration parameters, and further extension bits are also allowed.

Different timings, because different ways of dividing system messages will bring different resource bearers and transmission modes, the practice of using beam transmission and reception is introduced in the new generation mobile communication system, combined with beam correlation processing, system messages. The transmission and resource bearer modes of each part have special features. In addition, by designing unified signaling between different split modes, different split modes can be implemented or coexist in one system, that is, suitable for use in different application scenarios. In addition, since the receiving parameters of the second system message of the terminal device are generally notified in the PBCH in the related art, if there are not enough resources in the PBCH to notify the terminal device on which resources to receive the second system message, the disclosure may be adopted.

The method provided in this embodiment is different from the foregoing embodiment in that the first system message sent by the base station includes only the uplink transmission parameter or the receiving parameter of the second system message. In a possible implementation manner of the embodiment of the present disclosure, when the first system message includes the receiving parameter of the second system message, the base station sends an example manner of the second system message, which is the same as the foregoing embodiment in FIG. The method is the same, and the transmission diagram shown in FIG. 6 is also used. The terminal device in this embodiment needs to send an uplink signal after receiving the second system message, that is, the base station cannot determine to set the transmission as the second by using the uplink signal. The downlink beam of the system message. Therefore, in order for the terminal equipment in the coverage of the base station to receive the uplink transmission parameter, the base station may send the second system message to the terminal device by using multiple antenna ports or multiple beam indexes, that is, the second The system message needs to be transmitted by using multiple beams to cover the terminal devices in different locations. In another possible implementation manner of the embodiment of the present disclosure, when the first system message includes the uplink transmission parameter, the base station needs to send the terminal device to the terminal device. Transmitting a receiving parameter of the second system message, and transmitting, by the base station, the system message in the foregoing embodiments Type is different, in the following exemplary implementation of the exemplary embodiment described the case. The second system message form is more diverse, and may be information in an LTE-like SIB, or a system message transmitted in a data sharing channel, or a system message transmitted in a second PBCH other than the PBCH.

Optionally, in the embodiment of the present disclosure, the foregoing description has indicated that the indication information may indicate different content, and if the indication information is set to indicate that the first system message includes a receiving parameter of the second system message, the terminal is implicitly implied. The uplink information may be received after the second system message is received. If the indication information is set to indicate that the first system message includes an uplink transmission parameter, the indication information may be further extended to indicate that the first system message includes Which uplink transmission parameter, that is, the indication information can also be set to indicate different uplink transmission parameter configurations. For example, the configurations of three different uplink configuration parameters may be respectively represented by 01, 10, and 11 of the 2 bits.

Optionally, FIG. 18 is a flowchart of another method for transmitting a system message according to the second embodiment of the present disclosure. The foregoing has been described above. When the indication information is set to indicate that the first system message includes the uplink transmission parameter, the first system message further includes the uplink transmission parameter. Before the S320, the embodiment may further include:

S311. The base station receives an uplink signal sent by the first terminal device according to the uplink transmission parameter.

S312. The base station sends, to the first terminal device, a downlink signal that is set to respond to the uplink signal, where the downlink signal includes a receiving parameter of the second system message.

The S320 is implemented in the embodiment that the base station sends the second system message to the first terminal device on the basic time domain resource unit that carries the second system message according to the receiving parameter of the second system message.

The method provided in this embodiment may further include: after S312:

In the case of multi-beam transmission and reception, the uplink transmission is, for example, a transmission of a random access signal, and the uplink transmission and the downlink beam have a mapping relationship, so that the base station can determine the downlink relationship with the uplink signal by receiving the uplink signal. The beam, that is, which beam is a suitable downlink beam, is used to facilitate the use of the appropriate downlink beam when transmitting the second system message. When the appropriate downlink beam is selected, the second system message can use only the determined downlink beam. Sending and receiving are performed; optionally, the second system message may be transmitted and received using a partial downlink beam adjacent to the determined downlink beam in addition to using the determined downlink beam transmission to improve the probability and stability of beam reception. After the terminal device receives the second system message, the other uplink signal may be sent according to the uplink transmission parameter in the second system message. It can be seen that the transmission mode shown in FIG. 19 is different from that shown in FIG. 4 in that the first system message does not have the receiving parameter of the second system message, and therefore, the base station can perform random access through the random access process. The response signaling sends the receiving parameter of the second system message to the terminal device, and the transmission mode shown in FIG. 4 does not need to send the downlink signal set to respond to the uplink signal.
