Performance of UMTS high speed downlink packet access for data streaming applications

Abstract

This paper summarises the main principles behind HSDPA (High Speed Downlink Packet Access) for UMTS, as is currently being specified in 3GPP (3rd Generation Partnership Project) (see 3GPP[1]). It considers the performance that may be achieved for streaming services and presents simulation results showing that HSDPA can support real-time streaming. The effects of different packet scheduling algorithms and antenna diversity are also discussed.
