摘要

全双工、协同通信和设备到设备(D2D)通信被认为是5G移动网络的关键技术。本文推导了全双工(FD)中继辅助D2D通信在底层模式下的最佳功率分配方法。D2D发射机充当FD中继来辅助蜂窝下行传输。考虑了放大转发和解码转发中继协议。目标是在满足蜂窝用户的最低速率要求的同时最大化D2D接收器的可实现速率。采用优化技术减少全双工模式产生的自干扰。

Power Adaptation for Full-Duplex Relay-Aided D2D Communications with Direct Link

Full duplex, cooperative communications and device to device (D2D) communications are considered as key technologies for 5G mobile networks. In this paper, an optimum power allocation for full-duplex(FD) relaying aided D2D communications in underlaying mode is derived. The D2D transmitters act as FD relays to assist cellular downlink transmissions. Both amplify-and-forward and decode- and forward relay protocols are considered. The objective is to maximize the achievable rate for the D2D receiver while fulfilling the minimum rate requirements of the cellular user. Optimization technique is used to reduce the self interference resulted from the full-duplex mode.
