A distributed resource allocation scheme was proposed for relaying networks utilized orthogonal frequency division multiple access (OFDMA) technique. The problem was described as a relaying non-cooperative power allocation game (RNCPAG) between the node B and the relay node, and two utilities functions were exploited taking the maximum utility function as the optimization criterion. Moreover, on the constraints of the limited total transmission power, the existence of Nash equilibrium was investigated, while the proposed algorithm converged to a unique Nash equilibrium. Compared with the traditional uniform power allocation scheme, the study shows that the proposed scheme can significantly improve the performance in terms of system capacity and resource utilization within a few steps of iteration.
