Abstract: 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.

Abstract: A method apparatus and system for efficiently transmitting and receiving channels are provided in a wireless communication system based on Orthogonal Frequency Division Multiplexing (OFDM). A multiplexing scheme differs according to a channel when a transmitter transmits a packet data channel, a common control channel and a control channel designated for a particular user. Uncoded 1-bit information is broadly dispersed in frequency and time domains using multiplexing technology for maximizing diversity gain in a channel for transmitting information of at least one bit to a particular user like an acknowledgement (ACK) channel. The transmitter converts a sequence obtained by multiplexing multiple bits to be transmitted to a plurality of users to parallel signals, and broadly disperses the parallel signals in the time and frequency domains.

Abstract: 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.
