Abstract
A method and system for open loop power control in a CDMA communication system. The method and system controls the power of a mobile station transmission signal in a CDMA communication system having a base station which transmits a pilot signal. The method includes calculating, in the base station, a base station pilot transmit power value, and a base station receiver sensitivity value. The base station transmits the pilot transmit power value and the receiver sensitivity value to said mobile station. In turn, the mobile station calculates a mean output power in response to the base station pilot transmit power value and the base station receiver sensitivity value.

A method for controlling the power of a mobile station transmission signal in a CDMA communication system having a base station which transmits a pilot signal, the method comprising the steps of:
- calculating, in said base station, a base station pilot transmit power value;
- calculating, in said base station, a base station receiver sensitivity value;
- transmitting said pilot transmit power value and said receiver sensitivity value to said mobile station;
- and
- calculating, in said mobile station, a mean output power in response to said base station pilot transmit power value and said base station receiver sensitivity value.
A system for controlling the power of a mobile station transmission signal in a CDMA communication system having a base station which transmits a pilot signal, the system comprising:
- a base station controller in said base station, for calculating a base station pilot transmit power value and a base station receiver sensitivity value;
- a base station transmitter for transmitting said pilot transmit power value and said receiver sensitivity value to said mobile station;
- and
- a mobile station controller in said mobile station, for calculating a mean output power in response to said base station pilot transmit power value and said base station receiver sensitivity value.
