%X MIMO/OFDM is an effective architecture for future wireless communication systems. An adaptive cross-layer spatial subchannel allocation algorithm based on multiuser MIMO/OFDM systems is proposed in this paper. With the goal of maximizing overall data throughput in the physical layer we derive the criteria of subcarrier allocation and develop the adaptive allocation approach by using the T-ARQ technology in the link layer. The simulation results show that our proposed algorithm can achieve good performance and high total transmission rate efficiently.
