- Abstract
In order to optimize the problem of co-channel interference(CCI) after introducing the deviceto-device(D2D) relay communication, and to meet the cellular user capacity requirements, a D2D relay selection algorithm based on energy efficiency combined resource allocation with power control is proposed. Firstly, the algorithm allocates spectral resource to the equivalent D2D relay links, reduces the complexity of the algorithm and minimizes the interference caused by the D2D link to the cellular link, and then selects the relay based on the resource allocation result and the power control algorithm. The scheme considers not only the energy efficiency of the D2D relay link but also the cellular interference problem. Simulation proves that the proposed algorithm can not only improve the energy efficiency of the D2D relay link, but also reduce the interference to the cellular users.
