Abstract

In order to solve the problem of co-channel interference between base station and D2D users caused by fixed path loss compensation coefficient in existing power control algorithm of device to device (D2D) communication in cellular network, a packet-based power control algorithm was proposed. Based on the traditional closed-loop power control algorithm, the proposed algorithm calculates the supplement of the path loss compensation coefficient by the distance from D2D users to base stations and cellular users, and sets three groups of interference regions to distinguish the supplement of the path loss compensation coefficient. Finally, the joint closed-loop power is used to suppress the interference of the system. Simulation results show that, compared with the traditional closed-loop power control algorithm, the signal to interference plus noise ratio (SINR) and throughput of the system can be improved to a certain extent by using this algorithm, which can significantly improve the power control performance of D2D communication in cellular networks and achieve the effect of interference suppression.
