METHOD AND DEVICE FOR TRANSMITTING RANDOM ACCESS PREAMBLE

WIPO Patent Application WO/2020/101330

A1

Provided are a method for transmitting a random access preamble in an unlicensed band and a device using same. The device determines a clear channel assessment (CCA) scheme for a transmission resource which is selected from a dynamically indicated transmission resource candidate set. The device transmits a random access preamble from the selected transmission resource according to the determined CCA scheme.
