A resource dispatching method for orthogonal frequency division multiplexing communication system

The utility model relates to a resource scheduling method for an orthogonal frequency division multiplex communication (OFDM communication) system, comprising: firstly, dividing all sub-carriers in the system frequency resources into a plurality of resource blocks, and showing the channel status messages of a user from all sub-carriers in the resource blocks by characteristic quantity; secondly, under the request to the quantity of resource blocks, allocating resource blocks according to the channel status messages of users; thirdly, stopping if no resource block conflict occurs; if a resource block conflict occurs, continuing the following step; fourthly, only allocating the resource blocks with conflicts to the users with the best channel status in the resource blocks; fifthly, allocating the undistributed resource blocks in the segment of the undistributed resource blocks together, if a resource block conflict occurs, transferring the conflicted resource block to the resource blocks occurring conflicts; repeating the fourth and fifth step until all resource blocks are allocated. The utility model has the advantages of simplifying allocation process, ensuring higher system performance, and perfectly realizing equity among all users, and guaranteeing real-time transmission with less complexity.
