Abstract
Disclosed are: a communication technique for merging, with IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4G system; and a system therefor. The present disclosure can be applied to intelligent services (for example, smart home, smart building, smart city, smart car or connected car, healthcare, digital education, retail, security, and safety-related services, and the like) on the basis of 5G communication technology and an IoT-related technology. The present invention relates to a method and an apparatus for channel access in a wireless communication system operating in an unlicensed band. More particularly, disclosed are a method by which a node for transmitting a signal through an unlicensed band determines a channel occupation state of the unlicensed band, and a method for transmitting the signal to the unlicensed band according to the determined channel occupation state of the unlicensed band.
