Abstract:
1. A method of controlling a radio frequency resource between a wireless unit and a base station, the method comprising: receiving at the base station information indicating the radio frequency resource used by the wireless unit, the feedback information being received at a first time during a feedback cycle and wherein the feedback cycle has a duration equal to a predetermined time interval; estimating at the base station said radio frequency resource used by said wireless unit and the base station at a plurality of subsequent times within the feedback cycle using the feedback information indicating a rise over thermal resource at plurality of subsequent times, the plurality of subsequent times being subsequent to the first time and falling at equal intervals within the feedback cycle; and providing a plurality of overload control signals, each overload control signal being provided in response to estimating the radio frequency resource at one of the plurality of subsequent times; causing said base station to issue a command to provide the overload control at each of the plurality of subsequent times, wherein providing said command comprises providing said command to control a data rate of a reverse link between the wireless unit and the base station; and relieving an overload condition, at said base station, in response to issuing the command to provide the overload control at said base station by reducing said data rate to a rate that provides a desired timely rate control based on a target level of the rise over thermal resource using information not limiting to an availability of samples of feedback information.
