摘要：

Relay power control for two-way (TW) full-duplex (FD) relay network is studied in this letter. In the prior literature, the relay is assumed to always use its full transmit power in a TWFD relay network. However, high transmit power will increase loopback self-interference at the relay node and thus make the incoming link to the relay become the bottleneck for the end-to-end performance. Therefore, it is suboptimal to always utilize the full power capability of the relay. Thus, we propose three relay power control schemes, which can, respectively, maximize 1) the data rate of an individual end node, 2) the minimum data rate of the two end nodes, and 3) the sum data rate of the two end nodes. Numerical results show that, compared to using full relay power, the proposed relay power control schemes can improve system performance while reducing relay power consumption.
