A method and an apparatus for operating a base station and a terminal in a wireless communication system using an unlicensed band are provided. The base station can determine at least one channel in at least one unlicensed band using one of a single channel operation and a multi-channel operation, acquire the at least one channel according to a data transmission request, and transmit a channel preservation signal until a start point of a first subframe transmitted on the acquired at least one channel."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for operating a base station and a terminal in a wireless communication system using unlicensed frequency band","description":"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","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9794899","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
