Method of reverse link dynamic power control in a wireless communication system using per-flow quality feedback for multi-flow data traffic
First Claim
1. A method in a wireless communication system in which an access terminal (AT) communicates with a base transceiver station (BTS) over a reverse link (RL) and a forward link (FL), the method comprising:
- at the AT;
dynamically controlling a traffic-to-pilot ratio (TPR) of a non-delay sensitive data flow being transmitted on the RL in response to a quality indication feedback received on the FL of the non-delay sensitive flow received by the BTS.

Abstract
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.

17. A method in a wireless communication system in which an access terminal (AT) communicates with a base transceiver station (BTS) over a reverse link (RL) and a forward link (FL), the method comprising:
-
at the AT; dynamically individually controlling a traffic-to-pilot ratio (TPR) of each of a plurality of non-delay sensitive data flows being transmitted on the RL in response to an individual quality indication feedback received on the FL of the associated non-delay sensitive flow received by the BTS. - View Dependent Claims (18)
