Method of controlling power on forward link in a cellular CDMA system

摘要

A method of controlling transmission power of a plurality of base stations associated with a mobile unit in a CDMA (code division multiple access) cellular system, is disclosed. The mobile unit communicates with one base station among the plurality of base stations. According to the present invention, power of each of pilot signals respectively transmitted from the plurality of base stations is measured at the mobile unit Following this, information about a measured power value of each of the pilot signals is transmitted to the one base station. Thereafter, a first power control coefficient is determined at the one base station. The coefficient is a ratio of total pilot power values of the plurality of base stations, other than the main base station, to a pilot power value of the one base station. Subsequently, the transmission power of each of the plurality of base stations using the first power control coefficient is controlled. IMAGE IMAGE
