<p>A method for allocating and identifying frequency resources in an FDMA(Frequency Division Multiple Access) system and an apparatus thereof are provided to reduce signaling overhead by providing information indicating the amount of frequency resource available and indicating which frequency resource among the entire frequency resources is to be used, in the FDMA system, such as OFDMA(Orthogonal Frequency Division Multiple Access) and SC-FDMA(Single Carrier Frequency Division Multiple Access) systems, in which a base station schedules data transmission of several terminals by allocating frequency resources. A method for allocating and identifying frequency resources in an FDMA(Frequency Division Multiple Access) system comprises the following several steps. A terminal receives scheduling information from a base station(700). Thereafter, the terminal determines whether the received scheduling message is an AG(Absolute Grant) message or an RG(Relative Grant) message(701). If the scheduling message is the AG message, the terminal discards the existing channel information(702), and sets new channel information as a resource for data transmission(703). However, if the scheduling message is the RG message, the terminal sets a resource for data transmission as an allocated frequency resource using relative information generated on the basis of the existing channel information(705). Thereafter, for both cases, the terminal performs data transmission(704).</p> |
