Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is an application scenario diagram of a carrier allocation method provided in the present invention. As shown in fig. 1, a base station may establish at least one cell, e.g., cell 1, cell 2, and cell 3. When a base station establishes each cell, it needs to allocate a corresponding carrier to a resource pool in the cell to perform service transmission. The carrier allocation method provided by the invention allocates the carriers which can meet the service quality requirement of the resource pool for each resource pool according to the service priority of the resource pool and the interference noise of the available carriers of the cell. The following describes the method for allocating carriers according to the present invention in detail by using specific embodiments.
Fig. 2 is a first flowchart illustrating a carrier allocation method according to the present invention. The main execution body of the method is a carrier allocation apparatus, which may be, for example, a baseband processing Unit (BBU) in a Base station. As shown in fig. 2, the method includes:
s201, obtaining service priority of each resource pool in a plurality of resource pools in a cell.
The service priority of the resource pool may be pre-configured according to actual service needs, for example, if the delay requirement of the service is high, the service priority is configured to be a high priority. The service priority may be configured through Man-Machine Language (MML), the service priority of each resource pool configured in advance may be stored in a configuration file, and the service priority of each resource pool may be obtained by reading the configuration file. For example, M resource pools are configured in a cell, service priority values of the M resource pools range from 0 to M-1, and the larger the priority value is, the higher the service priority of the resource pool is.
S202, acquiring interference noise of each carrier in the available carriers of the cell.
The cell available carrier may be all carriers that may be allocated to the resource pool, and different carrier interference noise is different, so that in order to enable the allocated carrier to meet a service requirement of the resource pool, interference noise of the carrier needs to be considered, and therefore interference noise of each carrier in the cell available carrier needs to be obtained, specifically, the interference noise of each carrier sent by a Radio Remote Unit (RRU) may be received. For example, in a base station including an RRU and a BBU, the RRU performs carrier scanning to obtain interference noise of each carrier before establishing a cell, and reports the interference noise of each carrier to the BBU.
S203, allocating carriers to each resource pool according to the service priority of each resource pool and the interference noise of each carrier.
In order to ensure that the carrier allocated to each resource pool can meet the service quality requirement of the resource pool, the carriers are allocated according to the service priority and the interference noise of the carriers, the carriers with better interference condition are allocated to the resource pool with higher service priority, and the carriers with worse interference condition are allocated to the resource pool with lower service priority.
In practical application, different carrier allocation orders can be selected according to needs, and in a possible implementation manner, carriers are allocated to each resource pool according to the order of the service priority of the resource pool from high to low and the interference noise of each carrier. That is, firstly, the resource pool with the highest service priority is allocated with carriers, the carrier with the best interference condition is allocated to the resource pool with the highest priority according to the interference noise of each carrier, and then the carriers are allocated to other resource pools in sequence from high to low according to the priority until the allocation is completed.
In another possible implementation manner, carriers are allocated to each resource pool in the order of the service priority of the resource pool from low to high, and the interference noise of each carrier. That is, firstly, carrier allocation is performed on the resource pool with the lowest service priority, the carrier with the worst interference condition is allocated to the resource pool with the lowest priority according to the interference noise of each carrier, and then carrier allocation is performed on other resource pools in sequence from low to high in priority until allocation is completed.
In the method for allocating carriers provided in this embodiment, the service priority of each resource pool in a plurality of resource pools in a cell and the interference noise of each carrier in available carriers in the cell are obtained; and allocating carriers to each resource pool according to the service priority of each resource pool and the interference noise of each carrier, so that the resource pool with higher service priority can be allocated to the carrier with better interference condition, and the service quality requirement of the service is met. In addition, the method for self-adaptive allocation according to the service priority and the carrier interference noise also avoids the problem of resource waste caused by configuring a fixed carrier position for a resource pool in the prior art.
On the basis of the foregoing embodiment, further description is made on allocating carriers to each resource pool according to the order of the service priority of the resource pool from high to low and the interference noise of each carrier in S203 by combining with an example. Fig. 3 is a flowchart illustrating a carrier allocation method according to a second embodiment of the present invention. As shown in fig. 3, the method includes:
s301, the number of carriers contained in a first resource pool is obtained, and the first resource pool is the resource pool with the highest service priority.
The number of carriers included in each resource pool in the cell may be preconfigured, and may be configured through MML, the preconfigured number of carriers included in each resource pool may be stored in a configuration file, and the number of carriers included in each resource pool may be obtained by reading the configuration file. In this embodiment, the carriers are first allocated to the resource pool with the highest service priority, that is, the number of carriers included in the first resource pool is first obtained.
S302, determining N candidate resource blocks in the available carriers of the cell according to the number, wherein N is a positive integer.
After the number of carriers contained in the first resource pool is determined, N candidate resource blocks are determined in the available carriers of the cell, wherein the number of carriers contained in each candidate resource block is the number of carriers contained in the first resource pool.
Optionally, the method shown in fig. 4 is adopted to determine the N candidate resource blocks. As shown in fig. 4, available carriers of a cell are acquired; and performing sliding window processing on the available carriers of the cell by taking the number of the carriers contained in the first resource pool as the length to obtain the N candidate resource blocks. Specifically, in fig. 4, the diagonal part is the cell available carrier, and assuming that the number of carriers included in the first resource pool is 4, 4 carriers starting from the sliding window start position of the cell available carrier are the candidate resource block 1, and then the position of one carrier is slid to obtain the candidate resource block 2, which is sequentially performed until the sliding window end position is reached to obtain the candidate resource block N.
S303, determining a Signal-to-Interference plus Noise Ratio (SINR) of each candidate resource block of the N candidate resource blocks according to the Interference Noise of each carrier.
The SINR of each carrier can be calculated according to the interference noise of each carrier, and the method for calculating the SINR is the same as that in the prior art, and is not described herein again. And averaging the SINR of the carrier wave in each candidate resource block to obtain the SINR of each candidate resource block.
S304, allocating carriers to the first resource pool according to the SINR of each candidate resource block.
The first resource pool is a resource pool with the highest service priority, so that a carrier with the best interference condition needs to be allocated to the first resource pool, and the method may specifically be implemented according to the following method:
calculating the difference between the SINR of the first candidate resource block and the SINR of other candidate resource blocks to obtain a plurality of SINR difference values; judging whether the maximum SINR difference value in the SINR difference values is larger than a preset value or not; if the maximum SINR difference value in the SINR difference values is larger than the preset value, allocating the carrier contained in the candidate resource block with the maximum SINR in the N candidate resource blocks to the first resource pool.
The first candidate resource block is any one of N candidate resource blocks, and if a maximum SINR difference among the SINR differences is greater than a preset threshold, it indicates that there is a large difference between interference conditions of at least two candidate resource blocks in the N candidate resource blocks, so that in this case, the candidate resource block with the best interference condition needs to be allocated to the first resource pool, and the candidate resource block with the highest SINR among the N candidate resource blocks has the best interference condition.
In addition, if the maximum SINR difference value among the SINR difference values is not greater than the preset value, allocating carriers to the first resource pool according to a sequence of the frequency domains of the carriers from low to high.
If the maximum SINR difference value among the SINR difference values is not greater than the preset value, it indicates that the difference in interference conditions among the N candidate resource blocks is small, and in this case, which resource block of the N candidate resource blocks of the carrier is allocated to each resource pool has a small influence on the service. Optionally, according to the order of the frequency domains of the carriers from low to high, the carriers with lower frequency domains are allocated to the first resource pool.
And S305, determining a second resource pool as a new first resource pool, taking the rest carriers as new available carriers of the cell, and repeatedly executing S301-S305 until all the resource pools are distributed with the carriers, wherein the second resource pool is the resource pool with the highest service priority in the rest resource pools except the first resource pool, and the rest carriers are other carriers except the carriers distributed to the first resource pool.
In the above S301-S304, the carrier allocation for the first resource pool with the highest service priority is completed, and then the above steps are repeatedly executed according to the sequence from the highest service priority to the lowest service priority until the carrier allocation for all resource pools is completed.
In the carrier allocation method provided in this embodiment, the number of carriers included in a first resource pool is obtained, where the first resource pool is a resource pool with the highest service priority; determining N candidate resource blocks in the available carriers of the cell according to the number, wherein N is a positive integer; determining the SINR of each candidate resource block in the N candidate resource blocks according to the interference noise of each carrier; allocating carriers to the first resource pool according to the SINR of each candidate resource block; and repeatedly executing the steps, and completing the carrier allocation of all the resource pools according to the sequence from high service priority to low service priority. The method allocates the candidate resource blocks with high SINR for the resource pools with high service priority by calculating the SINR of the candidate resource blocks, thereby ensuring that the carrier allocated for each resource pool can meet the service quality requirement of each resource pool.
