Abstract  Abstract

Wherein one based on orthogonal frequency division multiple access (OFDMA) wireless communication system used for feeding back channel quality information and application apparatus and method for channel quality information of the scheduling. In the OFDMA wireless communication system reducing reducing the reverse channel quality information flow so as to induce the forward performance further suppressing the increase of the reverse load due to channel quality information feedback. Base station uses the information fed back from the mobile station to control the power of the physical channel. Wherein a moving method of a feedback channel quality information measuring one by one sub-frequency band channel quality information and sending a channel in the order of sub-bands of better channel quality information is channel quality information one by one. Measuring and sending used for average channel quality information for the total band.

An apparatus and method are provided for feeding back channel quality information and performing scheduling using the fed-back channel quality information in a wireless communication system based on Orthogonal Frequency Division Multiple Access (OFDMA). In the OFDMA wireless communication system forward performance degradation due to a decrease in an amount of reverse channel quality information is reduced and also an increase in the reverse load due to channel quality information feedback is suppressed. A base station controls power of a physical channel using information fed back from a mobile station. In a method for feeding back channel quality information from the mobile station sub-band-by-sub-band channel quality information is measured and channel-by-channel quality information of a number of channels is transmitted in order of sub-bands of better channel quality information. Average channel quality information for a total band is measured and transmitted.
