Common rate control method for reverse link channels in CDMA networks
First Claim
1. A method of dynamically adjusting the transmission rate of a mobile station, comprising:
- receiving periodic load indications from a radio base station indicative of the reverse link load at the radio base station;
changing transmission rate probabilistically if the load indication indicates that the reverse link load is within a first predetermined range;
changing transmission rate deterministically if the load indication indicates that the reverse link load is in a second predetermined range outside said first predetermined range.

Abstract
A radio base station transmits periodic load indications based on the measured reverse link load to a plurality of mobile stations transmitting on a reverse link channel. If the measure reverse link load is within a first predetermined range, the radio base stations transmits a load indication instructing mobile stations transmitting on the reverse link to change their transmission rate probabilistically. If the reverse link load is within second predetermined range outside the first predetermined range, the radio base station transmits a load indication instructing mobile stations transmitting on the reverse link to change their transmission rate deterministically.
