摘要： 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.

摘要： Methods and apparatuses are provided for transmitting feedback information in a communication system supporting multiple transmission methods with multi antenna transmission. Information for a default Multiple Input Multiple Output (MIMO) mode is received. It is determined whether the default MIMO mode is a Single-User MIMO mode or a Multi-User MIMO mode based on the information for the default MIMO mode. First Channel Quality Indicator (CQI) feedback information is calculated for one of the Single-User MIMO mode and the Multi-User MIMO mode determined as the default MIMO mode. The first CQI feedback information and DELTA CQI feedback information, which is a differential value between the first CQI feedback information and second CQI feedback information for a non-default MIMO mode, are transmitted.

摘要： An apparatus and method for transmitting/receiving data in a mobile communication system using multiple antennas are provided. A receiver estimates a fading channel of received data, selects a weight set relative to a maximum data transmission rate from at least one weight set with elements of a plurality of orthogonal weight vectors, and transmits feedback information including the selected weight set and channel-by-channel state information to a transmitter. The transmitter demultiplexes data to be transmitted on a basis of the feedback information into at least one sub-data stream, multiplies each sub-data stream by an associated weight, and transmits the data.
