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.
Claims23
In a communication system, a method comprising:
- forming a first stream of power control commands for controlling transmit power levels of a plurality of different data streams;
- controlling a transmit power level of at least a first and second data stream in said plurality of different data streams in accordance with the first stream of power control commands.
In a communication system, a method comprising:
- determining a first stream of power control commands;
- determining a second stream of power control commands;
- interleaving the first and second stream s of power control commands;
- transmitting the interleaved streams of power control commands to a first and second base stations for controlling transmit power levels of a plurality of different data streams.
In a mobile radio telephone communication system, a method comprising:
- forming a first stream of power control commands based on a first data communication from each base station in a first active set of base stations and from each base station in a second active set of base stations;
- transmitting, at a power level based on said first stream of power control commands, a first data stream from the first and second active sets of base stations to a mobile station;
- forming a second stream of power control commands based on the first data communication from each uncommon base station in the first and second sets of active base stations;
- transmitting to the mobile station, at a power level based on said second stream of power control commands, the first data stream from each uncommon base station in the first and second sets of active base stations.
In a communication system, an apparatus comprising:
- a power control command generator for forming a first stream of power control commands for controlling transmit power levels of a plurality of different data streams;
- a controller for controlling a transmit power level of a first and second data stream in said plurality of different data streams in accordance with the first stream of power control commands.
