    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 estimating a carrier to interference and noise ratio (CINR) in a mobile communication system based on a fractional frequency reuse are provided. The method includes receiving a report on CINR information on a common zone from a mobile station (MS) allocated a restricted zone, calculating a received signal power value using a CINR value and an interference level value for the common zone of the MS, and estimating a CINR value for a restricted zone using the received signal power value of the MS and an interference level for the restricted zone.
