Abstract:
1. A resource allocation method for an uplink packet data transmission in a wireless communication system based on Orthogonal Frequency Division Multiplexing (OFDM), comprising the steps of: allocating uplink resources from a base station to a plurality of terminals on a frequency bandwidth-by-frequency bandwidth basis; mapping the allocated resources to equal-interval sub-carriers or successive sub-carriers depending on a state of at least one of the plurality of terminals; generating resource allocation information for at least one of the terminals from the base station; and transmitting the generated resource allocation information from the base station to at least one of the terminals using a scheduling assignment channel, wherein the resource allocation information comprises an index (I) of a first sub-carrier allocated to at least one of the terminals, an interval (R) between sub-carriers, and the number (N) of sub-carriers.
