Controlling data transmission rate on the reverse link for each mobile station in a dedicated manner
DC CAFCFirst Claim
1. A method for controlling a data transmission rate on a reverse link in a mobile communications system including a plurality of base stations and a plurality of mobile stations, the method comprising:
- determining at a base station a data rate control command for controlling a transmission data rate of each mobile station to consider a channel condition or state of each mobile station;
sending each data rate control command via a forward common channel in a dedicated manner to the mobile stations, the data rate control command being formed of at least one rate control bit that is signal point mapped to at least one symbol of +1, −
1, and 0 to indicate whether the mobile station should increase, decrease, or maintain its current data transmission rate; and
allowing each mobile station to adjust or maintain its data transmission rate based on the data rate control command, wherein a bit received from the mobile station on a reverse packet data control channel indicates whether the mobile station has enough power and data to increase its data transmission rate on a reverse packet data channel.

Abstract
The data transmission rate on the reverse link in a mobile communications system is controlled by determining an interference level at a base station due to signals from all mobile stations served by the base station, and determining a transmission energy level required for each mobile station. The interference level is compared with the transmission energy level to obtain a comparison result for each mobile station, and each mobile adjusts its data transmission rate based upon the comparison result, which is sent via a common channel on a forward link to each mobile station in a dedicated manner. Thereafter, packet data is transmitted on the reverse link in accordance with the adjusting so that data throughput can be maximized.
