QoS support for the reverse packet data channel in third generation (3G) wireless networks

Third generation (3G) wireless networks have been designed to provide high speed data services on both forward and reverse links. In addition to increased data capacity they also support QoS (quality of service) guarantees for user applications. Users may run multiple applications (service instances) simultaneously and QoS guarantees may be required for one or more of them. In order to maintain these QoS guarantees the radio resources assigned to the mobile must be dynamically adjusted. Since mobile resources are assigned by the base station (BS) then each mobile must report relevant information to the BS so that it can make appropriate resource allocation decisions. The BS may either time-share or code share these resources. In this paper we present a simple framework to maintain QoS guarantees for each service instance of each mobile.
