The paper studies a distributed OFDMA system in which the transmitting nodes (source and relay) have access to channel information and to some interference-related information. Distributed subchannel allocation is modelled as a noncooperative game where the players are the source nodes. Channel-aware source nodes opportunistically select their subchannels while a channel-aware relay node assigns the input subchannels at relay to appropriate output subchannels in a way that maximizes the sum of utilities in terms of signal-to-noise ratio. Numerical examples illustrate the performance of distributed subchannel assignment; opportunistic channel allocation implies a trade-off between the average capacity and fairness.
