摘要： A method and apparatus for controlling a transmission (Tx) power in a mobile communication system based on fractional frequency reuse are provided. In a method of operating a base station (BS) for controlling the Tx power in the mobile communication system, the method includes receiving from neighboring BSs received signal strength indication (RSSI) information for one or more restricted band allocated, calculating backoff values of the Tx power for the restricted bands by using the RSSI information, and determining the Tx power for each restricted band by using a difference between the backoff value of the Tx power for the restricted band and a maximum Tx power. Accordingly, resources can be further effectively used.

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.
