摘要： Methods of reverse link power control are provided. In a first example reverse link power control process, a signal-to-interference+noise (SINR) is measured for a plurality of mobile stations. A power control adjustment is determined for each of the mobile stations based on the measured SINR for the mobile station and a fixed target SINR, the fixed target SINR being used in the determining step for each mobile station and sending the power control adjustments to the mobile stations. In a second example reverse link power control process, one or more signals are transmitted to a base station. A power control adjustment indicator indicating an adjustment to a transmission power level is received. The received power control adjustment is determined based on a measured signal-to-interference+noise ratio (SINR) for the one or more transmitted signals and a fixed target SINR threshold, the fixed target SINR threshold being used for power control adjustment of a plurality of mobile stations.

摘要： A closed loop power control based on receiving a continuous quality feedback is described. A main reverse link (RL) pilot is controlled by the quality feedback of a substantially continuous delay sensitive traffic stream, such as Voice-over-IP (VoIP), when such a stream is enabled. When such a stream is not enabled, the quality of a continuous RL overhead channel is used to control the pilot power. At the same time, the Traffic-to-Pilot Ratios (TPR) of contemporaneously transmitted delay sensitive data streams are independently adjusted based on a quality feedback associated with each such data stream.
