The invention discloses a resource allocation method and a server. The method includes: obtaining a directed graph of a small and medium-sized base station SBS network; according to the directed graph and a set grouping strategy, grouping each SBS in the SBS network to obtain several SBS groups; sub-channels are allocated for each SBS group. The present invention groups SBSs according to the interference between SBSs, and allocates subchannels for the SBS groups according to the actual needs of the SBS groups, which not only reduces the computational complexity, but also minimizes the interference between SBSs while ensuring the rate of users in the group. interference, which solves the problem in the prior art that the resource allocation strategy in the hybrid access mode has high computational complexity, while the allocation strategy with low computational complexity has strong co-channel interference between SBSs.
Description
technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a resource allocation method and a server. Background technique [0002] Ultra Dense Heterogeneous Network (UDN, Ultra Dense Heterogeneous Network) is one of the research hotspots in recent years. It effectively solves the problem of signal coverage in the case of dense distribution of users, but at the same time it also causes more network interference. Since they share the same frequency spectrum resource with the macro cell (Macrocell), when they use the same channel, serious co-channel interference may occur. At the same time, because small and medium base stations (SBS, Small cell Base Station) in ultra-dense networks are usually installed by users according to their own needs, it is difficult for communication network operators to obtain accurate base station locations, so it is difficult to carry out effective network planning to solve complex interf...
