Abstract
The present invention relates to a method for transmitting data in a wireless communication system, comprising the steps of: allocating, by a base station, a resource for transmitting data modulated by a hybrid frequency shift keying (FSK) and quadrature amplitude modulation (QAM) (FQAM) scheme in which a QAM scheme and a FSK scheme are combined; transmitting, by the base station, a sequence modulated by the FQAM scheme, to a mobile station, via an interference measurement channel; transmitting, by the base station, a reference signal for measuring channel quality information (CQI) to the mobile station; receiving, by the base station, CQI estimated based on an interference characteristic of the interference measurement channel, from the mobile station, and performing scheduling of the mobile station based on the received CQI; and transmitting, by the base station, the data modulated by the FQAM scheme to the mobile station.
