1. A method for forward link power control of transmissions of at least two data streams to a mobile station using a common power control channel, the method comprising:
- determining a first series of power control command data bits for controlling power level of a first data stream of said least two data streams;
determining a second series of power control command data bits for controlling power level of a second data stream of said least two data streams;
multiplexing said first and second series of power control command data bits to form a common series of power control command data bits;
transmitting said common series of power control command data bits over said common power control channel for controlling power levels of transmissions of said least two data streams to said mobile station.

Abstract
A method and apparatus for controlling transmit power levels of a plurality of different data streams transmitted from at least one base station to a mobile station in a mobile radio communication system is described. A stream of power control commands is formed at the mobile station in accordance with either the first or second received data stream. A power control signal is formed at the mobile station from the first stream of power control commands and transmitted to the base station.
