Abstract :
Most of the fair queueing algorithms that have been proposed in the literature assume no multiple simultaneous transmissions or are for operation on the downlink. In this paper, we propose an architecture for employing these algorithms on both downlink and uplink in CDMA networks which allow multiple simultaneous transmissions. The architecture addresses the issue of time scheduling using a new generalized processor sharing (GPS) approach that utilize the available power resource efficiently by assigning variable power indices to the mobile stations. Operation in error-prone channels is enabled by a mechanism that compensates mobile stations which experience poor channels. This approach supports multirate transmission techniques such as variable spreading gain or multicode.
