摘要

设备到设备(D2D)通信的底层资源共享模式会对D2D用户(会费)和蜂窝用户(cue)产生强烈干扰，这已成为当前D2D和蜂窝混合网络面临的主要挑战。不同于以往的一个或多个D2D链路和一个蜂窝链路共享信道资源，本文考虑了D2D链路复用多个蜂窝子信道以提高网络频谱利用率的新情况。会费功率和信道分配问题可以重新定义为一个目标优化问题，以最大限度地提高会费和cue的信道总容量。此外，提出了一种矩阵信道分配算法，该算法为每个DUE分配至少一个蜂窝子信道。仿真结果表明，该方案能有效提高网络性能。

Joint Power and Channel Allocation for D2D Underlaid Multi-user Cellular Networks

The underlay resource sharing mode of Device-to-Device (D2D) communication can strongly interference between D2D users (DUEs) and cellular users (CUEs), which has become a major challenge of the current D2D and cellular hybrid network. Different from the previous one or more D2D links and one cellular link sharing channel resources, the novel case of D2D links multiplexing multiple cellular sub-channels for improving the spectrum utilization of the network is considered in this paper. The DUEs power and channel allocation problem can be redefined as an objective optimization problem to maximize the total channel capacity of the DUEs and CUEs. In addition, a matrix channel allocation algorithm is proposed, which allocates at least one cellular sub-channels for each DUE. Simulation results show that the scheme can effectively improve the network performance.
