Apparatus and method for signaling control information related to transmission scheme in wireless communication system

A second device in a wireless communication system, the second device comprising:

• a transceiver configured to:
• transmit, to a first device, capability information of the second device indicating a signal processing rule required to use an integer forcing (IF) reception algorithm using an effective channel matrix converted into an integer matrix by using an equalization matrix,
• receive, from the first device, control information on a transmission scheme for processing data determined based on the capability information, and
• receive, from the first device, a data signal generated using the transmission scheme,
• wherein the capability information comprises at least one of a rule for combination of channel coding and modulation or a rule for bit-to-symbol mapping.
