Abstract

Downlink Shared Channel (OSCH) is used for high-speed packet service transmission in WCOMA. The power-controlled performances of the OSCH are studied through simulation works. Under various channel conditions and mobile speeds, the simulation results show that current power control scheme in WCDMA, especially for the OSCH power control, has some problems. In this paper, cause of problems is revealed. Also, the quantitative result related to the OSCH power control problem is analyzed.
