1. A method for controlling transmit power level of at least two data streams received at a mobile station from one or more base stations, comprising:
- determining a first stream of power control commands for controlling transmit power level of a first of the at least two data streams;
determining a second stream of power control commands for controlling transmit power level of a second of the at least two data streams;
multiplexing at the mobile station the first and second streams of power control commands to form a multiplexed stream of power control commands.

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.
