摘要： A base station using multiple antennas receives channel quality information from a terminal so as to allocate uplink/downlink resources to the terminal. Herein, the channel quality information is measured on the basis of a downlink preamble or pilot signal, and may include a received CINR or received signal strength. In addition, the base station predicts a received SINR by using a channel response and channel quality information between the multiple antennas and the terminal, and allocates a resource to the terminal according to the received SINR.

摘要： Disclosed is an apparatus for transmitting feedback information to a base station. The feedback information transmitting apparatus receives channel allocation information, generates a plurality of payloads regarding feedback information, and multiplexes the plurality of payloads in terms of a plurality of classes so as to generate a plurality of multiplexed payloads. Subsequently, the plurality of multiplexed payloads are code multiplexed so as to generate a code division multiplexing symbol, and a channel code is applied to the code division multiplexing symbol. Then, the code division multiplexing signal applied with the channel code is transmitted to a base station through a wireless resource. Accordingly, a feedback channel that is adaptive to a channel condition is configured, such that a wireless resource for a feedback channel can be efficiently used.
