Description

Method and device for resource allocation

The present invention relates to the field of wireless communications, and in particular, to a method and an apparatus for resource allocation.

Background technique

In a Long Term Evolution (LTE) wireless communication system, frequency resources are allocated in units of resource blocks (RBs), and each communication channel can be transmitted only when RB resources are allocated, and uplinks are performed. The channels on which the RB resources need to be allocated include: Physical Uplink Control Channel (PUCCH), Physical Uplink Shared Channel (PUSCH), and Physical Random Access Channel (PRACH), The coding and debugging modes of the three channels are different. If the RB resources are not allocated properly, the data transmitted between these channels will interfere with each other, affecting the key performance indicators such as resource utilization of the system.

It can be seen that the reasonable allocation of resource blocks for each communication channel in the uplink is very important for the stability of the communication performance of the entire LTE wireless communication system. The PUCCH only transmits information such as ACK/NACK (Ia/Reject) and UCI corresponding to the data, and the number of physical resources RBs is small, so the occupied RB of the general PUCCH is located at the edge of the system bandwidth.

In the existing LTE system, before the data is transmitted, the resource block RB is reserved for the PUCCH at both ends of the bandwidth, and after the resource block is allocated for the PUCCH at one time, the PUSCH resource block is allocated, and then the data transmission is performed. .

The RBs occupied by the PUCCH channel may not be located at the edge of the system bandwidth, and may be located in the middle of the system bandwidth. In this case, PUCCH and PUSCH channels are mutually generated. Interference is not conducive to the full utilization of spectrum resources, and ultimately affects the stability of the entire system.

The number of resource blocks that need to be reserved for one information is K; Step S2: allocating the first to ith resource blocks of the M resource blocks, and the Mjth to Mth resource blocks to the first information, Where i is less than j, the sum of i and j is Κ, and M is a positive integer greater than K;

Step S3: In the ΤΉ, the number of resource blocks required to calculate the second information that needs to be sent through the physical uplink control channel corresponding to the data is P;

Step S4: determining whether the P is greater than the K, and obtaining a determination result; Step S5: When the judgment result indicates that the P is greater than the K, allocate the first to the i+ (QK)/2 resource blocks in the resource blocks based on the maximum allocation principle, and the jth - (QK) /2 to Mth resource blocks to the second information, where Q is greater than or equal to P and less than M.

It can be seen that, in the embodiment of the present invention, by using step S2, K resource blocks are allocated for the first information, and the minimum number of resource blocks that can ensure that the physical uplink control channel is to send information is implemented.

In a specific implementation process, it is possible to preset that there are 100 resource blocks in the physical uplink, that is, M=100. The implementation process of the method in the embodiment of the present invention is described in detail below by taking M=100 as an example. :

In step S1, when there is data to be transmitted from the terminal in the LTE communication system to the base station, based on the principle of minimum allocation, the calculation corresponding to the data needs to be sent through the physical uplink control channel. The number of resource blocks that need to be reserved for the first information is K, so that K=4;

Then, in step S2, half of the Κ value is allocated from each end of the 100 resource blocks to the first information, that is, two at each end of the 100 resource blocks, that is, the first to the second resources are allocated. Piece, And the 99th to 100th resource blocks are given the first information (i=2, j=99);

In step S3, in the ΤΉ, the number of resource blocks required to calculate the second information that needs to be sent through the physical uplink control channel corresponding to the data is six;

Step S4, determining whether the 6 is greater than the 4, and obtaining a judgment result;

Obviously, 6 is greater than 4, and at this point, step S5 is performed, namely:

And assigning at least three resource blocks to the second information, that is, the first to the third and the 98th to the 100th, respectively, at the two ends of the 100 resource blocks;

Of course, if the P obtained by the calculation in step S3 is 3, or 4, the judgment result obtained by the step S4 indicates that P is less than or equal to K, and at this time,

Go to step S2.

As shown in FIG. 1 , before S1, step S6 is further included: determining whether to open the resource dynamic allocation adaptive function in the LTE system;

When it is opened, step S1 is executed to start using the resource dynamic adaptive function;

Otherwise, step S5 is performed to directly allocate the resource block from the first to the i+th (QK)/2 of the M resource blocks according to the maximum allocation principle, and the j-th (QK)/ 2 to M, wherein Q is greater than or equal to P and less than M.

It can be seen that, in the resource allocation method of the embodiment of the present invention, since a judgment is performed before using the resource dynamic adaptive function, when the system does not open the resource dynamic allocation adaptive function, the physical uplink control channel is used according to the maximum allocation principle. The information transmitted on the resource allocation block solves the problem that the resource dynamic block function of the physical uplink control channel is not enough when the resource dynamic adaptation function is not turned on immediately, and the resource block for the physical uplink control channel is always maintained. Adequate technical effects.

As shown in FIG. 2, after S3, the method further includes the steps of:

And an arrangement diagram of the output resource blocks, where the locations of the P resource blocks arranged in the M resource blocks are used. As shown in FIG. 2, step S4 is specifically:

Checking the i+1th to jthth resource blocks of the physical uplink control channel, if there are ACK/NACK information and UCI information corresponding to the data is located in the i+1th to jthth One resource block indicates that the P is greater than the above.

It can be seen that, in the embodiment of the present invention, after the resource block P required for calculating the second information is used, the arrangement diagram of the resource blocks on the physical uplink control channel is output, and the P resources that can pass through the arrangement map are solved. The arrangement position of the block in the M resource blocks checks whether the resource block of the second information is located outside the range of the physical uplink control channel.

Preferably, after allocating resource blocks for the uplink control channel, outputting the first information or the second information to the physical uplink control channel, so that the first information or the second information Information is stored in a demodulated message buffer of the LTE communication system.

It can be seen that, in an embodiment of the present invention, the resource dynamic adaptive function is used to ensure the resource block that needs to be sent on the physical uplink control channel, and then the information to be sent is stored in the demodulation message cache.
