METHOD FOR ALLOCATING SUBCHANNEL AND CONTROLLING INTERFERENCE IN THE OFDMA SYSTEM AND APPRATUS OF ENABLING THE METHOD

摘要

PURPOSE: A method for allocating subchannel and controlling interference in the OFDMA system and apparatus of enabling the method are provided to enhance the total throughput. CONSTITUTION: The subchannel allocation coefficient determination unit(311) decides the subchannel allocation coefficient by using the signal to Interference of the queue length of the terminal and terminal and relay and noise ratio. One or more terminal locates in the orthogonal frequency division multiplexing system. The subchannel allocation coefficient determination unit decides the subchannel allocation coefficient at one or more link. The subchannel allocation coefficient is decided based on each subchannel. The subchannel allocation part(312) uses the subchannel allocation coefficient. Subchannel is assigned to one or more link formed in the OFDMA system phase. In order to maximize the sum total of the subchannel allocation coefficient of the links, the subchannel allocation part assigns subchannel to one or more link.
