摘要

Method of control of transmission power in a mobile communication sistemaf, base station and mobile station in code division multiple access (CDMA) for a system of mobile communication.When a mobile station transmits a message to access, first with a small power, through a control channel to a base station, and after that,Gradually increases the transmission power until it receives a response of the base station to communicate with the minimum transmission power.A mobile station informs the base station on a message access and the transmission power of the mobile station.And a base station calculates an initial value of the transmission power of the base station.It is necessary for the base station to transmit at the start of the communication through the communication channel assigned to the mobile station.At this point, the initial power is calculated based on the transmission power of the mobile station is added to the message of access from the mobile station.
