Method and apparatus for determining reverse data rate in mobile communication system
First Claim
1. A method of controlling reverse data rates in a mobile communication system having an AN (Access Network) and a plurality of ATs (Access Terminals) in one cell, comprising the steps of:
- determining, in the AN, rate control information according to a reverse link load for each of the plurality of ATs; and
sending, from the AN, the determined rate control information to each of the plurality of ATs.

Abstract
A reverse data rate determining method in a mobile communication system for high data rate transmission such as an HDR system, wherein an AN (Access Network) within a cell calculates a total load of a reverse link by measuring a total energy of a reverse link from ATs (Access Terminals) within the cell. The AN calculates the share of each AT in the total reverse link load. If the load share of an AT is greater than a threshold predetermined individually for the AT, the AN determines that the AT should reduce its data rate.

2. A method of controlling reverse data rates in a mobile communication system having a AN (Access Network) and a plurality of ATs (Access Terminals) in one cell, comprising the steps of:
-
receiving, in each of the plurality of ATs, rate control information that is determined by a reverse link load of each of the plurality of ATs; and
transmitting, in each of the plurality of ATs, packet data with a data rate corresponding to the received rate control information.
