Abstract:
1. A method of transmitting feedback information at a mobile station in a wireless communication system, the method comprising: receiving, at the mobile station, an allocation of a specific frequency partition from a base station by a fractional frequency reuse (FFR) scheme; generating, at the mobile station, first feedback information on the specific frequency partition allocated to the mobile station by measuring a channel quality of the specific frequency partition; generating, at the mobile station, second feedback information on a frequency partition unallocated to the mobile station by measuring a channel quality of the unallocated frequency partition; and transmitting, at the mobile station, the first and second feedback information to the base station, wherein a transmission period of the first and second feedback information is below or equal to an FFR dynamics period for indicating at least a configuration of inter-cell FFR and a number of FFR groups, or a period for changing a bandwidth per FFR group and power level in common.
