摘要 This paper proposes an efficient approach to optimize the performance of uplink transmission in IEEE 802.16e BWA networks. First, an enhanced bandwidth request (BR) scheme is designed, which takes all uplink nrtPS/BE connections in the same subscriber station (SS) or a rtPS/ErtPS connection as a unit to request bandwidth, as well as defines unicast polling index to indicate whether a SS needs to be polled. This approach reduces the BR delay and the signaling overhead caused by the BR scheme in IEEE 802.16e. Meanwhile, through cross-layer optimization, a joint bandwidth allocation (BA) and packet scheduling scheme is proposed to balance the tradeoff between QoS provision and system throughput under effective admission control. The theoretical analyses and the simulation results show that our approach achieves significant improvements in QoS provision, BR signaling overhead, and system throughput.
