Abstract: Disclosed is a 5G or pre-5G communication system for supporting a data transmission rate higher than that of a 4G communication system such as LTE. Disclosed are: a method for transmitting a signal in an unlicensed band channel on the basis of a counter reduction in the unlicensed band channel of a mobile communication system and a clear channel assessment (CCA) of the channel; and a mobile communication system, and according to an embodiment of the present disclosure, the method for transmitting a signal in an unlicensed band channel on the basis of a counter reduction in the unlicensed band channel of a mobile communication system and a clear channel assessment (CCA) of the channel comprises the steps of: reducing the counter and performing a CCA for the channel, during a first period of transmitting a discovery signal and data; storing the reduced counter when a second period of transmitting only the discovery signal without the data is started; reducing the counter by using the stored counter and performing the CCA for the channel when a third period of transmitting the discovery signal and the data is started; and transmitting the discovery signal or the data on the channel on the basis of the counter value.

Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). A method for performing device-to-device (D2D) communication by an in-coverage user equipment (UE) in a cellular communication system is provided. The method includes receiving a scheduling grant through a downlink control channel from a base station (evolved Node B (eNB)) and transmitting a scheduling assignment (SA) message in an SA region of a D2D communication frame and data in a data region of the D2D communication frame, based on the scheduling grant, wherein the scheduling grant indicates a resource pattern for transmission (RPT) corresponding to a set of resource units or a subset of a resource unit in a time domain and a frequency domain that is used for transmission of the data.
