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

This invention provides an orthogonal frequency division multiple access using a multi-hop relay scheme; relates to resource request and allocation method using a CDMA code (Code Division Multiplexing Access code) on the (OFDMA Orthogonal Frequency Division Multiplexing Access) based wireless access communication system. A plurality of terminals and a relay station and a multi-hop orthogonal frequency division having a base station multiple access-based wireless connection resource request from the communication system and the allocation method according to the invention, a number of the mobile station requesting resource allocation to the RS a first step with; A second step in which the relay station identifying the number of said plurality of terminals; And a third step of the RS requests a resource allocation to the plurality of terminals to the number information of the plurality of terminals to the base station; And a fourth step of the base station collectively to allocate resources to the plurality of terminals; The relay station includes a fifth step of allocating the resources allocated collectively to the plurality of terminals to the respective nodes.
