In this paper, we consider a downlink resource allocation algorithm in multi-cell Orthogonal Frequency Division Multiple access (OFDMA) systems. The resource allocation problem is modeled as a non-cooperative game. We define a specific utility function that can represent the capacity maximizing against co-channel interference in multi-cell. Then we present the resource allocation game that employs an Adaptive Modulation & Coding (AMC) scheme. The proposed algorithm is to maximize a discrete capacity that precisely characterizes the AMC levels. As a result of adopting AMC scheme, we expect co-channel interference to be more reduced.
