Abstract

The invention discloses a resource allocation method, device and base station of an LTE cell, which generates a resource allocation random factor M for the LTE cell based on the cell identification number of the LTE cell to be allocated resources; and then uses the resource allocation random factor M to generate a resource allocation random factor M The number K, the generated resource allocation random number K is greater than or equal to 0, less than or equal to N1‑N2, where N1 is the total number of physical resource blocks N1 corresponding to the system bandwidth of the LTE system, and N2 is the total number of physical resource blocks that need to be scheduled in the LTE cell currently; according to The resource allocation random number K determines the starting position of the physical resource block allocation of the LTE cell; the physical resource block is allocated for the LTE cell from the starting position. It can be seen that the present invention allocates physical resource block resources of each LTE cell in a randomized manner, which can greatly reduce the probability of overlapping use of physical resource blocks between LTE cells, reduce the probability of mutual interference between adjacent cells, and improve the performance of the overall network.

Description

technical field [0001] The present invention relates to the communication field, in particular to a resource allocation method, device and base station for an LTE cell. Background technique [0002] With the development of wireless broadband communication technology, solving the interference problem of wireless systems has become a hot topic at present. As the mainstream technology of wireless communication, the LTE system adopts the same frequency networking, and the interference problem is one of the unavoidable problems; in the existing LTE wireless communication system, the wireless resource allocation method is based on the physical resource block (PRB, PhysicalResource Block) as the unit, and the PRB allocation method of each cell is the same, and the lowest frequency is used as the starting position of the PRB to allocate to the high frequency band, which leads to overlapping use of the PRB resource blocks of the low frequency part between the cells, please refer to ...
