Spatial subchannels in multiuser Multiple-Input Multiple-Output/Orthogonal Frequency-Division Multiplexing (MIMO/OFDM) systems are invested. With the goal of maximizing the overall system throughput, we derive the criterion of subcarrier allocation and introduce an adaptive resource allocation algorithm. Furthermore, a time-frequency blockwise loading design which may decrease the computational complexity is suggested. The simulation results show that the algorithm can achieve good performance and high transmission rate efficiently.
