A Research on the Improvement of Resource Allocation Algorithm for D2D Users

In the 5G communication network, D2D technology is considered to be one of the important components of the future [1]. D2D users bring multi-plexing gain to the channel resources of multiplexed cellular users, improve system communication capacity, and reduce communication delay and terminal performance [2]. D2D also brings considerable interference to the reuse of cellular user channel resources [3]. The research on the resource allocation algorithm in D2D communication system mainly aims to reduce the interference between D2D users and cellular users. The improved bilateral rejection algorithm based on the best algorithm improves the stability and system performance of the whole communication system to a large extent [4].
