Abstract:

Device-to-Device (D2D) communications is a promising technique to provide wireless peer-to-peer communication services and to enhance resource utilization as well as spectrum efficiency. In this paper, a distributed resource allocation scheme involving several D2D broadcast groups is proposed. However, the great amount of interference caused by sharing resources among different D2D broadcast users may significantly affect the performance of other D2D users. Therefore, an efficient resource allocation method is necessary to coordinate the interference. Specifically, we formulate the interference relationships among different D2D broadcast groups as an innovative interference-aware graph based resource allocation algorithm. This scheme aims to minimize the number of “confiict UE” meanwhile mitigate interference among different D2D broadcast groups from affecting the performance of each other. The complexity of proposed scheme is lower than that of the optimal SINR/channel capacity scheme.
