摘要

Topic As for this invention offer the method of solving the fact that power spectral density of the terminal in the OFDMA system cannot be controlled.SolutionsAs for the said method, the topic which cannot control the carrier discharge electric power of the terminal due to the uncertain characteristic of the conveying wave number allotment of the terminal in the OFDMA system was considered, the aforementioned topic was solved by introducing the allotment possible maximum conveying wave number into the terminal combining AMC, power control and scheduling. By using this invention, the fear the problem that occurring carrier power of the terminal it is controlled optimumly by the system, at the carrier it discharges electric power with the possibility the terminal being maximum on the basis of specification completely, originating in being larger than largest entire discharge electric power of the gaso of carrier power, in specification power spectral density of the terminal being suddenly control impossible, it goes down, is greatly decreased, the large quantity in this case occurrence of the error mark is evaded, wastefulness of the electrical resource due to the passing restriction of the carrier is evaded.
