CDMA code based badnwidth request and allocation method for OFDMA multi-hop system

摘要

This invention provides an orthogonal frequency division multiple access using a multi-hop relay scheme (OFDMA; Orthogonal Frequency Division Multiplexing Access ) based wireless connection relates to a resource request and allocation method using a CDMA code (Code Division Multiplexing Access code) in a communication system. ; in accordance with the invention, and a plurality of terminals, and the relay station, the base station comprising A resource request and allocation method in a multi-hop OFDMA based wireless access communication system, the first step with a plurality of terminals requesting the resource allocation to the RS; A second step and that the relay station identifying the number of said plurality of terminals; And a third step for requesting resource allocation of the RS to the multiple of the number of the terminal information and the plurality of terminals to the base station; And a fourth step of allocating the resources the base station to the plurality of terminals in a batch; The resources allocated to the RS in a batch of the plurality of terminals and a fifth step of allocating to each terminal.
