Description

Method and device for allocating scheduling request SR resources

Technical field

The present disclosure relates to the field of communication technologies, and more particularly to a method and apparatus for allocating scheduling request SR resources.

Background technique

In a LTE (Long Term Evolution) system, when a terminal accesses a certain base station, the base station allocates resources (which may be referred to as SR resources) for transmitting a scheduling request (ie, SR). The resource configuration message corresponding to the SR resource is then sent to the terminal. The resource configuration message includes a time-frequency resource location of the SR resource, where the time-frequency resource location is a location of the corresponding resource block of the SR resource in the subframe. In this way, when the terminal needs to send the uplink data to the base station, the terminal sends a scheduling request to the base station on the SR resource allocated by the base station, and the base station allocates an uplink resource to the terminal, and the terminal sends the uplink data to the base station by using the uplink resource. The base station allocates different SR resources to different terminals, so that each terminal sends a scheduling request to the base station through its own SR resources.

In the process of implementing the present disclosure, the inventors found that at least the following problems exist:

Based on the foregoing allocation mode, when the number of terminals is large, the SR resources allocated for the terminal occupy a large amount of transmission resources, resulting in low transmission efficiency.

Summary of the invention

In this way, when the scheduling request sent by the target terminal conflicts with the scheduling request of other terminals, the target terminal may resend the scheduling request according to the retransmission mechanism, which improves the success rate of sending the scheduling request.

Optionally, the SR resource configuration message further carries a maximum number of times the scheduling request is sent, and the method further includes:

When the maximum number of transmissions of the scheduling request is reached, the sending of the scheduling request to the base station is stopped, and the SR resource configuration message is deleted.

In this way, the maximum number of times the scheduling request is sent is limited, and the situation that the network load is increased due to the retransmission of the scheduling request by the terminal multiple times can be avoided.

detailed description

Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. The following description refers to the same or similar elements in the different figures unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with aspects of the present disclosure as detailed in the appended claims.

Embodiments of the present disclosure provide a method for allocating SR resources, which may be implemented by a base station and a terminal. The terminal may be a PC ((personal computer) terminal, or may be a mobile terminal such as a mobile phone or a tablet computer. The base station may establish a connection with multiple terminals. As shown in FIG. 1 , the terminal is provided in this embodiment. The system framework diagram includes a base station and a plurality of mobile phones connected to the base station. The base station may include a processor, a memory, and a transceiver, where the processor may be a CPU (Central Processing Unit), etc. The SR resource is allocated to the target terminal, and the time-frequency resource location of the SR resource is determined. The SR resource is an SR resource commonly used by multiple terminals; the memory may be a RAM (Random Access Memory) or a Flash ( Flash memory, etc., can be used to store received data, data required for processing, data generated during processing, etc., such as time-frequency resource locations of SR resources. The transceiver can be used to send SR resource configuration to the target terminal. The message, the uplink resource configuration message, etc. In addition, the base station may further include components such as a power source and a network port.

The terminal may include a transceiver and a memory, where the transceiver may be configured to receive an SR resource configuration message sent by the base station, and send a scheduling request to the base station based on a time-frequency resource location of the SR resource; the memory may be a RAM (Random) Access Memory, Flash, etc., can be used to store received data, data required for processing, data generated during processing, such as SR resource configuration messages and upstream data to be sent. Wait. The terminal can also include components such as a power source, a display, and Bluetooth.

In step 201, when the preset SR resource allocation condition is reached, the base station determines the SR resource allocated for the target terminal.

The SR (scheduling request) resource may be a resource used by the terminal to send a scheduling request, and the SR resource may be an SR resource used by multiple terminals, that is, multiple terminals may use the same SR resource to send a scheduling. request. The scheduling request may be used to request the base station to allocate uplink resources to the terminal.

In an implementation, the base station may allocate the target terminal when the preset SR resource allocation condition is reached. For the SR resource, the target terminal may be any terminal that accesses the base station. The SR resource allocation condition may be various. For example, the base station may allocate the SR resource to the target terminal after the target terminal accesses the base station; or the network may be faulty during the running process (such as network restart or network interruption). The base station can re-allocate the SR resources for each terminal accessing the base station after the network failure is recovered. The SR resource may be an SR resource commonly used by multiple terminals in the base station, and may be referred to as a competitive SR resource.

When the base station allocates the SR resource to the target terminal, the SR resource may be selected as the SR resource of the target terminal, and then the time-frequency resource location of the SR resource may be obtained. Alternatively, the base station may determine, in the unused transmission resources, the SR resource that the target terminal sends the scheduling request, and then obtain the time-frequency resource location of the SR resource, and the subsequent base station may allocate other terminals to the SR resource. The time-frequency resource location may be used to indicate the location of the SR resource in the subframe. If the SR resources allocated by the base station to the target terminal are periodic, the base station can also determine the SR period of the target terminal. The SR period may be a period in which the target terminal sends a scheduling request, and the SR period may include at least one subframe. For example, if the SR period is 3, the target terminal can send a scheduling request every 3 MS (3 subframes). In addition, for the case where the base station sets the SR period of the target terminal, the time-frequency resource location may also be used to indicate the location of the subframe to which the SR resource allocated to the target terminal belongs in the SR period (ie, indicating that the SR resource is within the SR period) In several sub-frames). The SR periods of terminals using the same SR resource may be the same. In addition, the base station may also allocate the SR resource to the target terminal in the non-competitive transmission resource. At this time, the SR resource can only be used by the target terminal.

In step 202, the base station sends an SR resource configuration message to the target terminal.

The SR resource configuration message may carry the time-frequency resource location of the SR resource, so that the target terminal sends a scheduling request by using the SR resource.

In an implementation, after determining the SR resource allocated to the target terminal, the base station may send an SR resource configuration message to the target terminal, where the SR resource configuration message may carry the time-frequency resource location of the SR resource and the SR period of the target terminal. In addition, the base station may further configure at least one of logical channel indication information, logical channel group indication information, and terminal indication information. The terminal indication information may be used to indicate that the SR resource is allocated to the target terminal; the logical channel group indication information may be used to indicate that the SR resource belongs to a target logical channel group in each logical channel group corresponding to the target terminal; The information may be used to indicate that the SR resource belongs to a target logical channel in the target logical channel group. Correspondingly, the SR resource configuration message may further carry at least one of logical channel indication information, logical channel group indication information, and terminal indication information. In this way, the target terminal can send scheduling information through the logical channel group configured by the base station and/or the SR resource in the logical channel.

Optionally, in order to facilitate distinguishing between the terminals that use the same SR resource, the base station may also allocate an identifier to the target terminal, and the corresponding processing may be as follows: assign the terminal identifier of the target terminal in the SR resource to the target terminal. Correspondingly, the SR resource configuration message may also carry the terminal identifier of the target terminal.

In the implementation, the base station allocates the competitive SR resource to the target terminal, and the different terminals use the same SR resource to send the scheduling information. In order to distinguish the terminal that uses the same SR resource, the base station may allocate the target resource to the target terminal. The terminal identifier in the SR resource, the base station may store the terminal identifier of the target terminal and the SR resource correspondingly, and establish a correspondence between the terminal identifier and the SR resource. The subsequent target terminal may send a scheduling request carrying the terminal identifier, so that after receiving the scheduling request sent by the SR resource, the base station may determine, according to the terminal identifier in the scheduling request, the terminal that sends the scheduling request.

In step 203, the target terminal receives the SR resource configuration message sent by the base station, where the SR resource configuration message carries the time-frequency resource location of the SR resource allocated by the base station, and the SR resource is the SR resource commonly used by multiple terminals.

In an implementation, the target terminal may receive the SR resource configuration message sent by the base station, and then parse the SR resource configuration message, obtain the time-frequency resource location and the SR period carried therein, and further, according to the time-frequency resource location and the SR period. Determine the SR resource that the base station allocates for itself. If the SR resource configuration message further carries at least one of logical channel indication information, logical channel group indication information, and terminal indication information, the target terminal may determine according to the logical channel indication information, the logical channel group indication information, and the terminal indication information. The logical channel and/or logical channel group to which the SR resource belongs.

In step 204, the target terminal sends a scheduling request to the base station based on the time-frequency resource location of the SR resource.

In the implementation, when the target terminal needs to send the uplink data to the base station, and the target terminal does not currently have the uplink resource, the target terminal may send a scheduling request to the base station on the SR resource, so that the base station allocates the uplink resource for itself.

Optionally, the scheduling request may carry a local terminal identifier, and correspondingly, the target terminal needs to obtain the local terminal identifier, and the specific processing procedure may be as follows:

In the first manner, the pre-stored cell radio network temporary identifier is obtained, and the cell radio network temporary identifier is used as the local terminal identifier.

In an implementation, after the target terminal accesses the base station, the base station may allocate a C-RNTI (Cell Radio Network Temporary Identifier) to the target terminal. The C-RNTI The target terminal can be uniquely identified within the range covered by the base station (ie, within the cell). When the target terminal needs to send a scheduling request, the pre-stored C-RNTI may be obtained, and then the C-RNTI is added to the scheduling request and sent to the base station.

Manner 2: The terminal identifier in the SR resource configuration message is obtained, where the terminal identifier is a terminal identifier of the local terminal allocated by the base station in the SR resource.

In an implementation, as described above, after the base station allocates the SR resource to the target terminal, the base station may further allocate the terminal identifier of the target terminal in the SR resource to the target terminal, and the base station may carry the terminal identifier in the SR resource configuration message and send the target to the target. After receiving the SR resource configuration message, the target terminal may parse the SR resource configuration message to obtain the terminal identifier. When the target terminal needs to send a scheduling request, the target terminal may add the terminal identifier to the scheduling request, and then send the scheduling request to the base station.

Optionally, after receiving the scheduling request sent by the target terminal, the base station may allocate an uplink resource to the target terminal, and the corresponding processing may be as follows: receiving a scheduling request sent by the target terminal, where the scheduling request carries the terminal identifier of the target terminal; The terminal identifier of the terminal allocates an uplink resource to the target terminal, and sends an uplink resource configuration message to the target terminal, so that the target terminal sends the uplink data to the base station by using the uplink resource.

In an implementation, the target terminal may send a scheduling request to the base station on the SR resource allocated by the base station, where the scheduling request may carry the terminal identifier of the target terminal, and the terminal identifier of the target terminal may be a C-RNTI or the target terminal in the SR The terminal identifier in the resource. In addition, the scheduling request may further carry the current buffer state information of the terminal, the amount of data of the uplink data that needs to be sent, and the like. After receiving the scheduling request, the base station may parse the scheduling request to obtain the terminal identifier. For the case where the terminal identifier is the terminal identifier of the target terminal in the SR resource, the base station may determine, according to the pre-stored correspondence between the terminal identifier and the SR resource, the SR resource that receives the scheduling request, and the terminal identifier, to send the scheduling request. Target terminal. Then, the base station may allocate an uplink resource to the target terminal, and send an uplink resource configuration message to the target terminal, so that the target terminal sends the uplink data to the base station by using the uplink resource. For the case where the terminal identifier is C-RNTI, the base station can directly determine the target terminal through the C-RNTI.

Optionally, the target terminal is configured to send a scheduling request based on the competitive SR resource. When multiple terminals send the scheduling request through the SR resource at the same time, the scheduling request of the target terminal may fail to be sent. The mechanism for improving the success rate of sending a scheduling request may be as follows: if the uplink resource configuration sent by the base station is not received within a preset waiting period If the preset backoff duration is reached, the scheduling request is sent to the base station again until the uplink resource configuration message sent by the base station is received.

In the implementation, the waiting time of the uplink resource configuration message may be pre-stored in the target terminal, and the target terminal may start timing after sending the scheduling request to the base station. If the uplink resource configuration message sent by the base station is not received when the preset waiting time is reached, the scheduling request transmission fails. The target terminal may determine the backoff duration and start retime counting. When the backoff duration is reached, the target terminal may resend the scheduling request. The manner in which the target terminal determines the backoff duration can be varied. For example, the target terminal may pre-store the duration of the backoff duration, such as [0, 20 ms], and the target terminal may randomly select a duration in the duration range as the backoff duration. Alternatively, if the SR resource of the target terminal is periodic, the target terminal may store a ratio range of the backoff duration to the SR period, such as [1, 4], and the target terminal may randomly select a value in the ratio range, and use the The value is multiplied by the duration of the SR period to obtain the backoff duration. For example, the selected ratio is 3, and the duration of the SR period is 5MS, and the backoff duration is 15ms. When the backoff time is reached, the target terminal may resend the scheduling request to the base station, and then wait. If the uplink resource configuration message sent by the base station is received within the preset waiting time, the scheduling request is stopped, and subsequent processing is performed. Otherwise, the backoff duration is determined, and the scheduling request is sent when the backoff duration is reached, and so on, until the target terminal receives the uplink resource configuration message sent by the base station.

Optionally, in order to prevent the terminal from resending the scheduling request multiple times, the network load is increased, and the base station may set the maximum number of times the scheduling request is sent. Correspondingly, the processing process of the target terminal may be as follows: when the maximum number of transmission requests is reached. Stop sending a scheduling request to the base station and delete the SR resource configuration message.

In an implementation, the base station may allocate the SR resource to the target terminal, and may also set the maximum number of times the scheduling request is sent. Then, the maximum number of times the scheduling request is sent may be carried in the SR resource configuration message and sent to the target terminal, where the target terminal receives the SR. After the resource configuration message, the maximum number of transmissions can be obtained. The target terminal may count the sent scheduling request to obtain the number of scheduling requests that have been sent. For example, the target terminal increments by one every time a scheduling request is sent based on the SR resource. The target terminal may determine whether the number of scheduled scheduling requests is equal to the maximum number of transmissions. If not, the scheduling request may be continued to be sent to the base station based on the retransmission mechanism; if yes, the scheduling request is stopped from being sent to the base station, and the SR may be deleted. The resource configuration message, for example, the MAC module of the target terminal may notify the RRC module to delete the SR resource configuration message (ie, release the SR resource).

In the embodiment of the present disclosure, when the preset SR resource allocation condition is reached, the SR is allocated to the target terminal. a resource, the SR resource is an SR resource that is used by a plurality of terminals, and then sends an SR resource configuration message to the target terminal, where the SR resource configuration message carries the time-frequency resource location of the SR resource, so that the target terminal sends the scheduling request by using the SR resource.
