Abstract :
High rate packet data (HRPD) is a high speed (up to 2.4 Mbps) third generation wireless network specification that has been developed for bandwidth intensive data and multimedia applications. In HRPD, the sector throughput can be maximized by having the frame scheduler take into account the instantaneous radio conditions of users and by serving users during their good radio condition periods. This results in high user diversity gains. However, in order to support QoS services, it is also necessary to serve users experiencing bad radio conditions in order to maintain their requested QoS levels. We present a flexible algorithm that provides user QoS guarantees while at the same time achieving some user diversity gains.
