Game Theoretic Framework for Inter-Cell Interference Coordination

Inter-Cell Interference Coordination (ICIC) is commonly identified as a key radio resource management mechanism to enhance system performance of 4G networks. This paper addresses the problem of ICIC in the downlink of cellular OFDMA systems where the resource selection process is apprehended as a congestion game. Proving the existence of Pure Nash equilibriums (PNE) shows that stable resource allocations can be reached by selfish Base Stations (BS). We resort to a fully decentralized algorithm proposed by Berenbrinck et al [1] to attain the PNEs of the modeled game. Each BS will strive to select a pool of favorable resources with low interference based on local knowledge only.
