Reverse data transmission apparatus and method in a mobile communication system
First Claim
1. A method of transmitting reverse data to a base station in one of a plurality of mobile stations in a mobile communication system, comprising the steps of:
- receiving information about a maximum allowable data rate (MADR) from the base station in a first predetermined frame period;
determining a data rate equal to or lower than the MADR and requesting the determined data rate to the base station; and
starting data transmission if an MADR received from the base station in a second frame period following the first frame period is higher than the requested data rate.

Abstract
A reverse data transmission apparatus and method in a mobile communication system. A mobile station receives information about an MADR (Maximum Allowable Data Rate) from a base station in a first predetermined frame period, determines a data rate equal to or lower than the MADR, and requests the determined data rate to the base station. If an MADR received from the base station in a second frame period following the first frame period is higher than the requested data rate, the mobile station starts data transmission. Then, the mobile station measures a traffic to pilot ratio (T/P) from the base station and controls the data rate according to the T/P during data transmission.
