摘要： An apparatus and a method for transmitting uplink feedback data in a broadband wireless mobile communication are provided. The method comprises dividing tiles used as a feedback channel into a preset number of groups, selecting one group among the preset number of groups using a downlink channel, selecting a number of tiles, the number of tiles being equal to a number of tiles required for feedback data transmission in the selected group, and mapping feedback data to each selected tile. Thereby, feedback information can be transmitted via a tile selected by a terminal based on a channel state without a process of allocating and reallocating an additional feedback channel, thus enhancing efficiency of uplink wireless resources.

摘要： An apparatus and method for transmitting and receiving Channel Quality Information (CQI) in a communication system. A Base Station (BS) transmits, to a Subscriber Station (SS), a request for CQI of a resource region corresponding to a frequency reuse factor K, which is designated by the BS. The BS then receives, from the SS, the CQI of the resource region corresponding to a channel quality measured by the SS. The channel quality is measured by the SS by measuring a boosted reference signal and compensating the boosted reference signal for a non-boosted signal.
