The method includes when a position of an active tone hits a position of a pilot tone of an adjacent cell, the active tone corresponding to a tone boosted through an application of a hybrid Frequency Shift Keying (FSK) and Quadrature Amplitude Modulation (QAM) Modulation (FQAM) scheme among tones included in an FQAM symbol based on the FQAM scheme in which a QAM scheme and a FSK scheme are combined, detecting two or more tones, which do not hit the position of the pilot tone among the tones included in the FQAM symbol, and transmitting signals by using the detected two or more tones."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for transmitting/receiving signal by using multiple modulation and coding schemes in wireless communication system","description":"A method of transmitting a signal using a plurality of modulation and coding schemes by a transmitter in a wireless communication system is provided.
