Abstract
In this paper, resource allocation problem for ultra-dense D2D communications is studied. In ultra-dense scenarios, the number of D2D user equipments (DUEs) is far bigger than the number of cellular user equipments (CUEs). The dense user equipments (UEs) increase the complexity of resource allocation problem. Firstly, the system model of ultra-dense D2D communications is described. Then the resource allocation problem of ultra-dense D2D communications is formulated. Next a fast resource allocation algorithm based on predatory search algorithm is proposed and analyzed. Finally, the analysis and simulation results validate that the performance of proposed scheme is very efficient and has a low algorithmic complexity. This scheme can be applied into the ultra-dense D2D communication networks.
