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). An apparatus of a base station of a first operator in a wireless communication system includes: at least one transceiver; and at least one processor operatively coupled with the at least one transceiver, and the at least one processor is configured to transmit a first signal during a first slot regarding the first operator in a contention duration, and to determine occupancy of a band in an access duration, based on a priority of the first operator, and the priority is determined according to at least one second signal which is detected before the first slot in the contention duration.

Device and method for sharing band in wireless communication system

The present disclosure relates to a pre-5-Generation (5G) or 5G communication system for supporting higher data rates beyond 4-Generation (4G) communication system such as long term evolution (LTE). According to various embodiments in the present disclosure, a method of operating a terminal in a wireless communication system comprises receiving information for indicating a pre-listen interval within an allocated channel occupancy time from a base station (BS), transmitting a reporting signal for indicating that occupancy of an unlicensed band by at least one node is not detected during the pre-listen interval, receiving resource allocation information for indicating uplink resources of the unlicensed band allocated based on the reporting signal, and transmitting uplink data through the uplink resources.

Apparatus and method for channel access in wireless communication system

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). An apparatus of a base station in a wireless communication system is provided. The apparatus includes at least one processor configured to determine a length of a channel occupancy period and a length of a contention period with respect to a band shared with other system, and a transceiver configured to, when detecting no signal of the other system until a time indicated by a back-off value in the contention period, transmit a signal over the band. A method of a base station in a wireless communication system is provided. The method includes determining a length of a channel occupancy period and a length of a contention period with respect to a band shared with other system, and when detecting no signal of the other system until a time indicated by a back-off value in the contention period, transmitting a signal over the band.
