MOBILE COMMUNICATION SYSTEM AND COMMUNICATION METHOD THEREOF

摘要

A mobile communication system for making communication between a mobile station and a plurality of base stations. A user data signal having its transmission power controlled is transmitted from a selected one of a plurality of base stations to a mobile station. A control data signal having its transmission power controlled similarly to the user data signal is transmitted from each of the plurality of base stations to the mobile station. The mobile station determines the qualities of the control data signals from the respective base stations, and selects, based on the determined qualities, a base station. The mobile station transmits the identification information of the selected base station to the plurality of base stations. The base station, identified by the identification information, controls the transmission powers of the user data and control data signals to transmit
