Method and apparatus for allocating and identifying frequency resources in a frequency division multiple access system

摘要

A method is provided for allocating and identifying frequency resources to a terminal in a Frequency Division Multiple Access (FDMA) system. The method includes receiving from a base station a scheduling message including frequency resource information; and calculating the allocated frequency resource based on relative information if the scheduling message is a Relative Grant (RG) message including the relative information generated on a basis of a currently used channel. The relative information includes one of an identifier of a terminal, or an identifier of a channel in use by the terminal as a terminal ID, state information indicating number of channel that stands for increase or decrease amount of frequency resources on a basis of the currently used channel, and, direction information indicating a direction of the state information.
