Abstract
This paper presents a study of packet scheduling enhancements for VoIP service over high-speed downlink packet access (HSDPA) in WCDMA. Taking VoIP traffic characteristics into account in Node B packet scheduling algorithm is a key element in achieving good performance and high VoIP capacity. The novelty of this study consists of dynamic transmission resource allocation method for VoIP service. Dynamic resource allocation takes the estimated channel conditions and the transmission requirements of a user into account to increase the efficiency of resource utilization. Simulation results produced with a dynamic system simulator indicate 20 % VoIP capacity gain achieved with the proposed enhancement when compared to the conventional even share resource allocation.Keywords
