Abstract

In this paper, a game theoretic power allocation and relay load balancing scheme for downlink transmission in an OFDMA-based cellular relay network is proposed. In the cell, a BS is located at cell center communicating with multiple users assisted by multiple relays. The relays adopt the decode-and-forward protocol and can cooperatively assist the transmission from BS to users. In order to assign the users to relays, achieve the load balancing among relays and distribute the power of relays among users while considering the total data rate of the network, a game theoretic scheme is introduced to solve the problem. Simulation results indicate that, the proposed game-based power allocation scheme can improve the average sum- spectral efficiency approximately 20% compared to the traditional scheme.
