Abstract
In WCDMA systems the down-link power allocation directly affects the cell deployment capacity, coverage, and system performances. Down-link power should be controlled at minimum but still satisfy the mobile stations' required signal to noise ratio. This paper mathematically proves that the down-link power allocation depends on the number of active mobile stations accessed to the base station. Therefore this paper proposes the dynamic down-link power allocation should be implemented to the WCDMA cellular systems.
