Abstract
A power control method of the invention may be applied to downlink power control, uplink power control, or both to support different quality of service levels for multiple channels per a mobile station. The power control method transmits control data between a base station and a multi-channel mobile station on a single communications channel or sub-channel to minimize or reduce overhead traffic from the control data.

A method for controlling power in a wireless communications system that supports multiple communication channels per mobile station, the method comprising the steps of:
- recognizing a first quality of service target for a first communications channel and a second quality of service target for a second communications channel;
- measuring a first quality of service parameter and a second quality of service parameter at a mobile station;
- transmitting control data over at least one of said first communications channel and said second communications channel to control downlink transmit power based upon the first quality of service parameter and the first quality of service target and incremental offset data for the second communications channel.

- recognizing a first quality of service target for a first communications channel and a second quality of service target for a second communications channel;
- measuring a first quality of service parameter and a second quality of service parameter at a mobile station;
- transmitting control data over a single control channel to control downlink transmit power based upon the first quality of service parameter and the first quality of service target and incremental offset data for the second communications channel.
A method for controlling power in a wireless communications system that supports multiple communication channels per subscriber, the method comprising the steps of:
- setting a first quality of service target for the first communications channel and a second quality of service target for the second communications channel;
- measuring a first quality of service parameter and a second quality of service parameter at a base station;
- transmitting control data over one of said first communications channel and said second communications channel to control uplink transmit power based upon a first difference between the first quality of service parameter and the first quality of service target and incremental offset data.
