Method and device for transmitting/receiving data rate information in a mobile communication system
First Claim
1. A method of generating reverse data rate indicating information in a mobile station after information about a maximum data rate available to the mobile station is received from a base station in a mobile communication system, the method comprising the steps of:
- determining the number of available reverse data rates less than or equal to the maximum data rate based on the maximum data rate information;
determining a number of bits to be assigned to the reverse data rate indicating information according to the number of available data rates; and
generating reverse data rate indicating information with the number of bits, mapped to the available data rates on a one-to-one basis.

Abstract
There are provided a method and device for transmitting/receiving reverse data rate information in a mobile communication system supporting multimedia service applications including voice and data services. According to the present invention, upon receipt of information about the maximum data rate of an SCH, a mobile station determines the minimum number of bits to be assigned to the reverse data rate information according to the number of data rates less than or equal to the maximum data rate and then transmits the reverse data rate information with the minimum number of bits to a base station.
