Abstract [en]

A Fixed Beam (FB) system that uses a beam specific Secondary-Common PIlot CHannel (S-CPICH)  as a phase reference for channel estimation and demodulation in WCDMA is evaluated in a dynamic radio network simulator.  The impact of the angular spread on the DownLink (DL) system performance is analyzed. Furthermore, various scrambling code allocation strategies  and an adaptive load-dependent power tuning algorithm of the common channels are proposed and evaluated. Extensive simulation results have verified that increasing the number of FB from 1 to 2 or 4 beams per sector in a typical urban radio channel yields significant DL capacity gains.
