摘要： 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.

摘要： 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). Embodiments of the present disclosure provide a method and an apparatus for efficiently controlling a handover process and a Radio Link Failure (RLF) process. According to embodiments of the present disclosure, an operating method of a User Equipment (UE) includes starting a first timer while a second timer regarding a radio link failure (RLF) is running, and if one of the first timer and the second timer expires, performing a radio resource control (RRC) connection re-establishment. When the handover and the RLF concurrently occur in the mobile communication system, the embodiments of the present disclosure can minimize the service interruption time by conducting the handover instead of the Radio Resource Control (RRC) connection re-establishment due to the RLF.
