Abstract :
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
