Abstract  Abstract

The present invention relates to an apparatus and method for feeding back channel quality information in a wireless communication system and performing scheduling by using the same. In particular, the present invention feeds back channel quality information in an orthogonal frequency division multiple access (OFDMA) type wireless communication system. An apparatus and method for performing scheduling using


The present invention provides an apparatus and method for reducing backward performance due to a decrease in quality information of a reverse channel in an OFDMA system and at the same time suppressing reverse load due to feedback, and an efficient scheduling apparatus and method. The present invention also provides an apparatus and method for performing power control on a physical channel of a base station using information fed back from a terminal.


The feedback method according to the present invention is a method for feeding back channel quality information in a terminal of an OFDMA wireless communication system. The channel quality information is measured for each preset subband, and the subbands having good channel quality information are pre-ordered. And transmitting the quality information for each channel by the determined number and measuring the average channel quality information for the entire band in the OFDMA wireless communication system.
