Abstract

A cell selection scheme for a CDMA mobile communication system which is capable of reducing an amount of interference power and thereby preventing the degradation of the system capacity. In this scheme, each base station transmits a perch channel which is spread by using a spread code assigned to each base station. Then, a mobile station receives more than one perch channels transmitted from more than one base stations, calculates a transmission attenuation value of each received perch channel, and judges a located cell according to calculated transmission attenuation values of these more than one perch channels.
