Effects of user distribution on the delay performance of downlink packet access in 3GPP WCDMA networks

Abstract

SUMMARYThis paper is concerned with the effects of user distribution on the delay performance of packet access in wideband code division multiple access (WCDMA) downlink networks. The characteristics of a packetswitched data traffic model which mimics internet web browsing is presented. The cellular system model is based on the release 4 configuration of the third Generation Partnership Project (3GPP) technical specification. The investigation incorporates traffic channel power allocation, fast power control, data traffic characteristics, data activity factor, different user distributions, hot-spot scenarios, base station sectorization schemes and antenna beam patterns. Two types of system level Monte-Carlo simulations are proposed and a performance comparison is given. The results include the overall delay performance and their sensitivities to a diverse set of parameters.
