RESEARCH CONTRIBUTIONS

Transmit Power Minimization for Two-Way Amplify-and-Forward
Relaying with Asymmetric Traffic Requirements

Two-way relaying (TWR) has received a great deal of research interest as it can enhance the spectrum efficiency and throughput of communication systems. In this work, we consider a half-duplex TWR system as shown in Fig. 1, where two end terminals TA and TB want to send, respectively, signal sA and signal sB to each other through the assistance of a half-duplex amplify-and-forward (AF) relay. We suppose multiple relays (N) are available but only one relay is selected for relaying cooperation. We addresses the power minimization problem subject to a target quality-of-service (QoS) constraint of the TWR with asymmetric traffic requirements using the AF relaying mode. By transforming the power minimization problem into a two-stage problem and using the traffic information together with the short-term channel knowledge, an optimum power control (OPC) scheme is first proposed, leading to closed-form solutions for individual transmit power at the relay and the sources. Then, by making use of the available diversity of the multiple-relay channel, the joint design of OPC and relay selection (RS) is investigated, eventually resulting in a joint power control and RS (JPCRS) algorithm with two decentralized RS policies for transmit power minimization. It is shown that our proposed strategies can significantly reduce the system transmit power, while ensuring the target QoS of the system, and that the proposed RS algorithm is superior to the conventional max–min and max-sum selection strategies in any traffic and channel conditions in terms of energy saving.

Fig. 2 plots the total power consumption of different RS strategies as a function of the terminal A to relay distance dAR (the distance between the two terminals is normalized to unity), when the relay number N = 3, the target system outage probability sQ=0.01 and the diversity gain d=1, respectively. Here we have considered three traffic scenarios, strongly asymmetric, moderately asymmetric and symmetric, as indicated by the target traffic rates rA and rB of the two terminals. It shows that the proposed optimum and sub-optimum policies perform much better than the conventional max-sum policy, and better than the max–min policy. Fig. 3 depicts the total power consumption versus the number of relays for selection, where dAR = dBR = 0.5, sQ = 0.01, and d = 1. It is seen that our policies perform better than the conventional max–min and max-sum policies for all the three traffic scenarios. Fig. 3 also shows that the total power consumptions of the optimal and suboptimal policies are almost identical, indicating that the simplified suboptimal policy can replace the optimal one to implement RS.
