基于信干噪比的D2D通信功率控制与资源分配
D2D Communication Power Control and Resource Allocation Based on SINR
摘要
Abstract
In order to solve the problem of co-channel interference(CCI) and the deterioration of system performance after introducing the device-to-device(D2D) communication to the Long Term Evolution(LTE) system,this paper proposes a multi-cell D2D communication resource allocation scheme based on signal-to-interference plus noise ratio(SINR).The scheme converts cellular user(CU) into D2D user by adjusting the threshold of the signal-to-noise ratio(SNR) and releases spectrum resource,and then obtains a better resource allocation strategy.Meanwhile,an allocation algorithm is proposed to reduce the inter-cell interference(ICI) based on the inter-cell D2D competition mechanism.Simulation shows that the proposed algorithm can effectively increase the system capacity and enhance the cell edge D2D users' fairness.关键词
