Abstract
A base station monitors mobile station response to rate grants by the base station to determine rate control violations by the mobile station. A rate control violation occurs when the mobile station fails to transmit at an expected rate after indicating a need to increase its transmit rate, or when the mobile station increases its transmit rate to the expected rate but transmits an unacceptable number of erroneous frames at the increased rate. The base station uses the observed rate control violations by the mobile station in making rate grant decisions.
Claims41
A method of controlling the data transmission rate of a mobile station on a reverse packet data channel, comprising:
- tracking rate control violations by the mobile station;
- and
- controlling the data transmission rate of the mobile station based on said rate control violations.
A base station comprising:
- a rate controller to detect rate control violations by a mobile station transmitting on a reverse packet data channel, and to generate rate control commands to control the data transmission rate of a mobile station.
