As system requirements are diversified, coexistence of multiple Radio Access Technologies (RATs) is the current situation, and traffic distribution between different RATs is different and even very different due to different operators in different geographical areas. From the present situation and the trend of network operation, operators want to be able to uniformly manage different systems coexisting in short term or geographical location to adapt to the optimization of network traffic characteristics and resource utilization. Typically, an operator wants to add a new generation network, for example, in a region or a time period where a network is already installed, and the operator wants to dynamically manage hardware resources and Radio resources of an existing system and the new generation network according to a change in cell traffic of a specific area, and this new technology used is called Cognitive Radio (CR) technology.
In a cognitive system applying the CR technology, a module for controlling resource Reconfiguration is a Reconfiguration module (Reconfiguration Entity), which may be disposed in a communication Entity such as a base station, and is mainly used to monitor a resource utilization condition of the base station and reallocate the resource, when a system change or a new system layout is involved, a control instruction of a policy control center is required, and a specific logical relationship is as shown in fig. 1. In fig. 1, when a policy control center has a new system requirement, a reconfiguration module is instructed to perform system upgrade or spectrum reformation; when a new system is not involved, the reconfiguration module may independently manage reconfiguration of resources, notify a Reconfigurable Base Station (RBS) to perform resource allocation and adjustment, or perform assistance processing by a Radio Resource Management (RRM) functional entity, and notify a terminal in a cell that resource adjustment has been performed after the reconfiguration of the base Station is completed. There are several application scenarios in the research of IMT-Band (International mobile telecommunications Band) of CR technology, such as the upgrade of the existing system; laying out a new system on the existing frequency band; there is also a re-planning of resource utilization within the system; resource adjustment and utilization among different systems, and the like.
At present, for the different application scenarios, different reconfiguration processes are adopted, and the core operation is that a reconfiguration module selects a new available frequency band or readjusts the layout of the existing frequency band, and then issues a reconfiguration command containing available frequency spectrum resources to a base station. However, since the reconfiguration module only makes a reconfiguration decision for the monitoring condition of the network side or the reporting condition of the base station side, the reconfiguration module is unclear as to whether the reconfiguration result is finally suitable for the reconfiguration utilization of the base station and the terminal, so that the new frequency band may have interference on other frequency bands, which may further affect the overall operation and user experience of the network, and reduce the benefit of resource reconfiguration.

Detailed Description
In practical application, the base station may issue a resource reconfiguration command to the terminal with measurement capability according to a reconfiguration control decision of the reconfiguration module.
The terminal performs reconfiguration measurement according to the received resource reconfiguration command and feeds back a reconfiguration measurement result to the base station;
the base station realizes resource reallocation based on the received reallocation measurement result, such as: the base station carries out control processing according to the received reconfiguration measurement result, or combines the reconfiguration measurement result with the self measurement information and reports the reconfiguration measurement result to the reconfiguration module, and the reconfiguration module carries out resource reconfiguration based on the received reconfiguration measurement result and the measurement information.
Specifically, after receiving the reconfiguration measurement result of the terminal, the base station may perform corresponding control processing, such as at least one of interference control, power control, and load control; and the base station can also combine the self measurement information with the reconfiguration measurement result from the terminal, report the combined reconfiguration measurement result and measurement information to the reconfiguration module, and the reconfiguration module processes according to the reconfiguration measurement result and the measurement information.
The terminal with the measurement capability comprises access point equipment, a mobile terminal and the like. The access point device may be a Relay Node (Relay Node), and the mobile terminal may be a User Equipment (UE).
The resource reconfiguration command includes one or more frequency band resources (frequency points, bandwidth), and in addition, may also include: effective time length, area range, measurement configuration information, transmission parameter limit information (power level, interference threshold), and the like.
When the terminal performs reconfiguration measurement according to the received resource reconfiguration command, the terminal may perform measurement according to the frequency band resource information indicated in the resource reconfiguration command to determine whether interference exists, and if a measurement signal of the designated measurement frequency band is greater than a preset threshold, it is determined that interference exists. The measurement Signal may be an absolute value, such as RSRP (Reference Signal Received Power), RSRQ (Reference Signal Received Quality); or a signal to interference Ratio (SINR). When interference exists, the terminal replies a reconfiguration measurement report to the base station; when there is no interference, the terminal replies an acknowledgement message to the base station. Optionally, if no interference exists, the resource reallocation is successful by default. The measurement information of the base station includes: at least one of the interference power received in the uplink and the thermal noise power in the uplink.
After the base station issues a resource reconfiguration command to the terminal, a reconfiguration monitoring timer (hereinafter referred to as a timer) can be started; if the base station receives the reconfiguration measurement report of the terminal within the timing range of the timer, the timer stops timing, and the base station performs resource reconfiguration or reports the reconfiguration measurement report to a reconfiguration module; and if the timer is overtime and the base station does not receive the reconfiguration measurement report of the terminal, the base station considers that the resource reconfiguration is successful and feeds back a reconfiguration completion message to the reconfiguration module to confirm the completion of the reconfiguration.
Further, the reconfiguration measurement feedback process can be performed after the terminal accesses the working frequency point.
It should be noted that, if the resource reconfiguration command issued by the base station includes information of multiple available frequency band resources, the terminal may measure multiple corresponding frequency bands and feed back status information of each frequency band to the base station. The state information includes: the measurement information of the interference signal may further include identification information of a frequency band that can be used for confirmation.
Optionally, after receiving the reconfiguration measurement result of the terminal, the base station performs resource reconfiguration on the terminal by using the available frequency band, and replies the reconfigured frequency band resource information to the reconfiguration module.
The above resource reallocation refers to the re-division of the band resources, or the re-allocation of new band resources.
The specific implementation process is as follows with reference to the attached drawings and the content of the invention:
example 1: the base station receives the resource reconfiguration command of the reconfiguration module, issues a frequency band resource information, and the terminal performs reconfiguration measurement and feedback, referring to the flow shown in fig. 2:
the monitoring condition of the network side or the reconfiguration request of the base station triggers the reconfiguration module to perform resource reconfiguration, the reconfiguration module runs the reconfiguration algorithm to generate a reconfiguration decision and issues a reconfiguration command to the base station according to the reconfiguration decision so as to indicate that the base station needs to perform resource reconfiguration. The reconfiguration command comprises: an available frequency band resource (frequency point, bandwidth) may further include the following information: maximum transmission power allowed by the terminal, available effective time, effective area range and the like.
After receiving the reconfiguration command, the base station issues an rrc (radio Resource control) reconfiguration command to the connected terminal, or may notify the idle terminal of the new band Resource information through a broadcast system message. The broadcast System message may be MIB (Master Information Block) or SIB1(System Information Block 1 ). The content of the notification, whether for the connected terminal or for the idle terminal, may further include: and measurement configuration information of the new frequency point, such as a measurement identifier, a measurement object (frequency), a measurement period, the number of measurement records, a measurement gap and the like.
And after receiving the RRC reconfiguration command or the broadcast system message, the terminal carries out periodic or event-triggered measurement on the new frequency band resource. If the measurement signal is larger than the preset threshold value, namely the newly reconfigured frequency point generates interference to other frequency points of the adjacent frequency or the local area, the terminal in the connection state immediately reports a reconfiguration measurement report to the base station; and the terminal in the idle state reports the reconfiguration measurement report to the base station after entering the connected state. The reconfiguration measurement report includes: newly reconfigured frequency points, geographical location areas, interference information, and the like. The geographical location area may be a cell identifier, or GPS location information, and the interference information may be interference signal strength, signal to interference ratio, or the like. The measurement signal may be an absolute value, such as RSRP, RSRQ, or SINR. And if the new frequency point does not cause interference to other frequency points and/or is not interfered by other frequency points, the terminal does not perform the feedback, and the base station succeeds in the default resource reconfiguration.
Further, if the terminal accesses to a new frequency point, the reconfiguration measurement can be performed again and a reconfiguration measurement report is fed back, and the reconfiguration measurement report may further include: channel quality indicator cqi (channel quality indicator), precoding Matrix indicator pmi (precoding Matrix indicator), rank indicator ri (rankindicator), and the like.
After receiving the reconfiguration measurement report, if the base station can perform interference control and/or power control on the access network side, the base station runs an interference control and/or power control algorithm and retransmits a resource reconfiguration command to the terminal; otherwise, the base station sends a reconfiguration measurement report to the reconfiguration module by combining the measurement information of the base station. The measurement information of the base station may include: the interference power received in the uplink and the thermal noise power in the uplink. The reconfiguration module operates a reconfiguration algorithm according to a reconfiguration measurement report of the terminal and the measurement information of the base station, allocates new frequency band resources to the base station according to the reconfiguration algorithm, and the base station reallocates the allocated resources to the terminal, thereby completing a resource reconfiguration process.
It should be noted that, if the base station receives the reconfiguration measurement reports of multiple terminals and the measurement results of different terminals contained therein are inconsistent (for example, the measurement result of the UE1 shows that the interference is large, and the measurement result of the UE2 shows that the interference can be tolerated), the base station performs statistical processing to determine whether to be interfered, for example: and if the measurement results of more than 80% of the terminals show that the interference is large, the corresponding frequency point is considered to be interfered in the current area). And then, the base station performs corresponding control processing.
Example 2: after receiving the resource reconfiguration command, the base station issues multiple frequency band resource information, and the related measurement configuration information may be carried in two messages, see the flow shown in fig. 3:
the monitoring condition of the network side or the reconfiguration request of the base station triggers the reconfiguration module to perform resource reconfiguration, the reconfiguration module runs the reconfiguration algorithm to generate a reconfiguration decision and issues a reconfiguration command to the base station according to the reconfiguration decision so as to indicate that the base station needs to perform resource reconfiguration. The reconfiguration command comprises: a number of available frequency band resources (a list of frequency points and bandwidth).
After receiving the reconfiguration command, the base station issues an RRC reconfiguration command to the connected terminal, or may notify the idle terminal through a broadcast system message, where the RRC reconfiguration command or the broadcast system message includes: a plurality of new frequency band resource information lists and measurement configuration information of each frequency point.
And after receiving the RRC reconfiguration command or the broadcast system message, the terminal carries out periodic or event-triggered measurement on each new frequency band resource. If the measurement signal is larger than the preset threshold value, namely the newly reconfigured frequency point generates interference to other frequency points of the adjacent frequency or the local area, the terminal in the connection state immediately reports a reconfiguration measurement report to the base station; and the terminal in the idle state reports the reconfiguration measurement report to the base station after entering the connected state. And for the frequency points which do not cause interference to other frequency points and/or are not interfered by other frequency points, the frequency points are represented by using the mark symbols.
The base station selects the frequency point with minimum interference to other frequency points or the frequency point without interference according to the received reconfiguration measurement report, and then retransmits the RRC reconfiguration command to the terminal, wherein the new RRC reconfiguration command comprises the following steps: available frequency band resources (frequency points, bandwidth) may further include: transmit power, frequency offset, cell identification, cell attributes, etc.). The cell attributes may be: CSG (Close Subscriber Group) cell.
Further, according to the received reconfiguration measurement result, if the base station still cannot select the available frequency band resource, the reconfiguration measurement report and the self measurement information are combined and reported to the reconfiguration module, the reconfiguration module executes the reconfiguration decision again, a resource reconfiguration command containing the new available frequency band resource is issued to the base station, and the base station reconfigures the resource to the terminal again.
Example 3: after the base station issues the RRC reconfiguration command, the base station controls the RRC reconfiguration command through the timer, and feeds back the RRC reconfiguration command when the RRC reconfiguration command interferes with or is interfered by other frequency points, or does not feed back the RRC reconfiguration command, referring to the flow shown in fig. 4:
the monitoring condition of the network side or the reconfiguration request of the base station triggers the reconfiguration module to perform resource reconfiguration, the reconfiguration module runs the reconfiguration algorithm to generate a reconfiguration decision and issues a reconfiguration command to the base station according to the reconfiguration decision so as to indicate that the base station needs to perform resource reconfiguration. The reconfiguration command comprises: one or more available frequency band resources (frequency points, bandwidth), may also include the following information: maximum transmission power allowed by the terminal, available effective time, effective area range and the like.
After receiving the reconfiguration command, the base station issues an RRC reconfiguration command to the connected terminal, or notifies the idle terminal of the new frequency band resource information through a broadcast system message. The content of the notification, whether for the connected terminal or for the idle terminal, may further include: and measuring configuration information of the new frequency point. Then, a timer is started.
After receiving the RRC reconfiguration command or the broadcast system message, the terminal performs periodic or event-triggered measurement on the new band resource. If the measurement signal is larger than the preset threshold value, namely the newly reconfigured frequency point generates interference to other frequency points of the adjacent frequency or the local area, the terminal in the connection state immediately reports a reconfiguration measurement report to the base station; and the terminal in the idle state reports the reconfiguration measurement report to the base station after entering the connected state. And if the new frequency point does not cause interference to other frequency points and/or is not interfered by other frequency points, the terminal does not perform the feedback, and the base station succeeds in the default resource reconfiguration.
If the base station receives the reconfiguration measurement report of the terminal within the timing range of the timer, the timer stops timing, and the base station performs corresponding control processing, or combines the reconfiguration measurement report reported by the terminal with the self measurement result and reports the reconfiguration measurement report to the reconfiguration module. The reconfiguration module can operate a reconfiguration algorithm according to a reconfiguration measurement report of the terminal and measurement information of the base station, so as to allocate new frequency band resources to the base station, and the base station reallocates the allocated resources to the terminal, thereby completing a resource reconfiguration process.
If the timer is overtime, the base station does not receive the reconfiguration measurement report of the terminal, and the base station defaults that the resource reconfiguration process is successful.
It should be noted that, if the timer expires, the base station defaults that the resource reallocation is successful.
As can be seen from the foregoing embodiments, in a system composed of a base station and a terminal, the operation idea of the present invention for implementing resource reallocation may be represented as a flow shown in fig. 5, where the flow includes the following steps:
step 510: and the base station transmits a resource reconfiguration command to the terminal with the measurement capability according to the reconfiguration control decision.
Step 520: and the terminal performs reconfiguration measurement according to the received resource reconfiguration command and feeds back a reconfiguration measurement result.
Step 530: and the base station realizes resource reallocation based on the received reallocation measurement result.
In summary, the technology for realizing resource reallocation can ensure the success rate of resource reallocation in the cognitive system and effectively improve the resource utilization rate regardless of the method or the system.
