In the light of the two-hop characteristics of relay networks

this paper proposes a resource allocation algorithm based on two-hop rate matching for multi-cell relay networks.It first independently allots subcarriers to all the users in every cell within the first sub-slot and builds a non-cooperative game-based power allocation model on the basis of the above allocation results.Then

it matches the second hop rate with the first hop resource allocation result

adaptively allotting resource to relay so as to meet the rate demand of the edge users.Simulation results demonstrate that while meeting the demand of the edge users for rate

the proposed algorithm further improves the throughput of the center users and reduces the system transmitting power

thus improving the system performances.
