In this paper, we investigate the cross-layer design of packet scheduling and adaptive resource allocation in multiuser MIMO-OFDM systems based on STBC. First we group different types of service into four types according to 802.16 protocol. Then we use a two-layer scheduling architecture to shape traffic at medium access (MAC) layer: the first layer schedules packets for different users of the same service type and the second layer schedules packets of different service types. At last, we propose a resource allocation algorithm that allocates wireless resource efficiently at physic (PHY) layer according to the scheduling results of the MAC layer. Compared with [8], simulation results show that our proposed algorithm can achieve significant improvement in packet drop rate, packet delay, and system throughput.
