Abstract

Wideband CDMA Release 5 is expected to support peak downlink bit rates of 10 Mbps for use with bandwidth intensive data and multimedia applications. Such rates are achieved through fast link adaptation, fast Hybrid ARQ and fast scheduling over a shared forward link packet data channel. Total throughput can be maximized by having the frame scheduler take into account the instantaneous radio conditions of users and serving users during their good radio condition periods. This results in high user diversity gains. However in order to support QoS guarantees, it will sometimes be 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.
