Strategies for resource allocation in wideband CDMA networks for high data rate applications

Abstract

Present generation wireless networks are being designed considering voice as the primary traffic. They are not suitable to support high data traffic rate. Third-generation standards are proposed to meet the increasing data traffic demand over mobile telephones. Wideband code division multiple access (WCDMA) is a promising technique for radio access in future cellular networks and personal communication systems. This paper deals with the problem of resource allocation in the forward link for wideband CDMA networks. Three types of user classes are assumed with data rate of 9.6 kbit/s, 144 kbit/s and 384 kbit/s respectively. A mixed dynamic and static algorithm is proposed, under the constraint that the base station is total transmitted power-limited. The performance of different classes of traffic is compared. A comparative study for voice and data traffic has been carried out.
