Abstract
A method and system for controlling power in a communication system are provided, in which a base station calculates a power control value for an mobile station based on feedback information received from the mobile station, transmits power control information including the power control value to the mobile station, measures the strength of a signal received corresponding to the transmit power control information from the mobile station, determines the status of the mobile station using the signal strength and the power control value, and schedules the mobile station according to the determination.
Claims32
A method for controlling power in a base station in a communication system, comprising:
- calculating a power control value for a mobile station based on feedback information received from the mobile station;
- transmitting power control information including the power control value to the mobile station;
- calculating a signal strength variation equal to a difference between a strength of a first signal received in a previous frame from the mobile station and a strength of a second signal received in a current frame from the mobile station, the first and second signals corresponding to the transmit power control information from the mobile station;
- calculating a racing metric value of the mobile station by dividing the signal strength variation by the power control value;
- determining a status of the mobile station by comparing the racing metric value with a racing threshold;
- and
- scheduling the mobile station according to the determination.
