Patent number: 10470211Abstract: 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.Type: GrantFiled: April 12, 2016Date of Patent: November 5, 2019Assignees: Samsung Electronics Co., Ltd., Korea University Research and Business FoundationInventors: Chung Gu Kang, Chung Kee Kim, Chan Seok Yang
