The present disclosure relates to a pre-5-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4-Generation (4G) communication system such as Long Term Evolution (LTE). A method of operating a terminal in a wireless communication system includes receiving control information for grant-free communication from a base station, generating a reference signal by using one sequence among sequences included in sequence set information for the reference signal included in the control information, and transmitting the reference signal and a data signal to the base station by using grant-free resource region information included in the control information. The one sequence may be used to allow the base station to identify the terminal.

Device and method for grant-free communication in wireless communication system

The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). A method of operating a receiving terminal in a wireless communication system may include: transmitting, to a transmitting terminal, information on capabilities of the receiving terminal in relation to an independent component analysis (ICA) technique; receiving, from the transmitting terminal, a signal generated based on the capabilities; and decoding the signal using the ICA technique in consideration of the amount of change in the channel for the signal.
