Downlink multi-user transmission for higher user speeds in IEEE 802.16m

A dynamic resource allocation algorithm with beam steering is evaluated for providing broadband wireless access to mobile users of the emerging IEEE 802.16 m air interface standard. Thanks to our design, the coverage area and total throughput may be significantly enhanced, compared to the current IEEE 802.16 e standard. Our proposed solution supports high mobility, improves fairness among the users and is backward compatible to the mobile networks based on the 802.16 e. The simulation analysis determines the parameters which impact the system performance. Furthermore, our system presents low complexity hardware implementation and low power consumption.
