Abstract: A method for transmitting a signal in a communication system includes transmitting a signal using pre-generated matrix, wherein the pre-generated matrix is generated by repeating one matrix including zero elements by a predetermined number of times and a particular sequence is allocated to non-zero elements included in the pre-generated matrix. An apparatus for receiving a signal in a communication system includes at least one processor configured to make a control to receive a transmitted signal based on a pre-generated matrix and to receive the signal, wherein the pre-generated matrix is generated by repeating one matrix including zero elements by a predetermined number of times and a particular sequence is allocated to non-zero elements included in the pre-generated matrix.

Abstract: The present invention relates to a method for operating, by a base station, multiple modulation schemes in a wireless communication system, the method comprising the steps of: calculating the number of terminals, among the terminals in a cell managed by the base station, of which a channel state is included in a state that is lower than a preset state; reporting information related to the calculated number of terminals to an upstream entity of the base station; receiving information about a band, assigned by the upstream entity, for a hybrid frequency shift keying (FSK) and quadrature amplitude modulation (QAM) (FQAM) scheme on the basis of a QAM scheme and a FSK scheme; and transmitting downwardly the information about the band for the FQAM scheme to the terminals of which a channel state is included in a state that is lower than the preset state. Other modified embodiments on the basis of the technical concept of the present invention are also possible.
