摘要：
A cross-layer resource allocation algorithm based on non-cooperative game theory model is proposed for the uplink of multi-user multiple input multiple output-orthogonal frequency division multiple (MIMO-OFDM) systems. After the base station (BS) assigning an initial uplink rate for each user, users minimize their power by a non-cooperative game approach. Users whose power does not saturate can still require BS for additional throughput. Users' channel conditions and buffer states in media access control (MAC) layer are taken into consideration when the BS adjusts users' throughput. Simulation results show that the algorithm can not only reduce power assumption but also maintain the fairness among users.
