Abstract

In third generation WCDMA systems, the major part of the overall traffic volume is expected to be inherently bursty. Shared channels are more suitable for the transmission of this type of traffic, as they allow many users to share a single orthogonal variable spreading factor (OVSF) code. In this paper, we propose a delay fair scheduling (DFS) to be used with the downlink-shared channel (DSCH). The proposed scheme is efficient and robust, providing QoS differentiation according to the delay sensitivity of each service, while it takes into account the constraints of the wireless OVSF-CDMA networks.
