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 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.

摘要： An apparatus and method for transmitting/receiving channel quality information (CQI) in a communication system having a frame including subchannels corresponding to the same frequency reuse factor or different frequency reuse factors. A base station (BS) allocates at least one of the subchannels in the frame to a subscriber station (SS), and sends a transmission request for a CQI for a subchannel desired to be received, to the SS. The SS measures channel quality for individual subchannels requested by the BS in response to the CQI request, and transmits the measured channel quality to the BS.
