Abstract: For the problem of interference and spectrum resource allocation in ultra-dense heterogeneous network under the hybrid access mode, a cluster-based resource allocation scheme was proposed. The scheme consists of two parts:the first part is to use simulated annealing algorithm to divide small cells into different clusters according to the interference between them; the other part is to use the minimum signal to interference plus noise ratio maximization algorithm to allocate sub-channels to the clustered network, and gives the user's resource usage mode under hybrid access mode. Simulations show that the proposed scheme can effectively suppress the interference and improve system performance.
