Abstract:
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, wherein the step of determining the number of bits comprises the steps of determining the number of the available data rates less than or equal to the maximum data rate among a set of given data rates, and determining the number of bits of the reverse data rate indicating information according to the number of the available data rates, and wherein if the number of the available data rates is m and the number of bits is k, k is the minimum integer equal to or greater than log
