Abstract
In this paper, we propose a hybrid centralized-decentralized resource allocation scheme for the downlink of two-hop relayed transmission. In the first-hop, a centralized joint power and subcarrier allocation is done. The second-hop is modelled as a virtual supply-demand market, and a two-level game is designed to find the Nash equilibrium. The proposed scheme has several advantageous including: (1) the resources of the first-hop are optimally exploited, (2) there is no overwhelm feedback overhead between the base station and relays, (3) the fairness among users is taken into account, (4) the interference is eliminated. In order to evaluate the proposed scheme, analysis and simulation results are presented.
