Method and apparatus for controlling reverse link data rate of a mobile station in a communication system with reverse link common rate control
First Claim
1. A method for controlling data rate of reverse link communications by a mobile station in a communication system, comprising:
- determining, by the mobile station, a target traffic to pilot channel power ratio (target-TPR);
determining, by the mobile station, whether to follow a fast-ramp-up behavior in adjusting a value of an authorized traffic to pilot channel power ratio (authorized-TPR) for said reverse link communications, wherein said authorized-TPR corresponds to at least a range of payload sizes and communication data rates for said reverse link communications, and wherein following the fast-ramp-up behavior causes the authorized-TPR to approach said target-TPR based on received TPR commands faster than not following the fast-ramp-up behavior; and
adjusting, by the mobile station, the value of said authorized-TPR in accordance with said determination of whether to follow the fast-ramp-up behavior.

Abstract
An efficient use of communication resources is provided by determining a behavior for selecting the payload size (data rate) of a reverse link transmission from a mobile station to a base station. The mobile station may store a predetermined table including the ratio of the power levels of the traffic channel and pilot channel (TPR), where each entry corresponds to one or more specific sizes of data payload, and consequently a data rate for transmission in a predetermined time frame. The payload size is selected based on an authorized-TPR. The authorized-TPR and a target-TPR are adjusted in accordance with a value of common TPR commands received from the base station. A fast-ramp-up behavior for adjustments of the authorized-TPR is followed when the authorized-TPR is less than the target-TPR. The down TPR commands are ignored in the adjustments of the authorized-TPR to allow following a fast-ramp-up behavior.
