| 1. A method for transmitting/receiving channel quality information (CQI) in a communication system including a base station
(BS) and a subscriber station (SS), the method comprising:
requesting, from the SS by the BS, CQI for downlink resources corresponding to a frequency reuse factor, which is designated
to the SS by the BS;
measuring, by the SS, channel quality of the downlink resources in response to the CQI request; and
transmitting, from the SS to the BS, CQI corresponding to the measured channel quality,
wherein the SS measures the channel quality by measuring a strength of a boosted reference signal and subtracting the strength
of the boosted reference signal from a strength of a reference signal.
