摘要

Provided are a method and device for performing wireless communication in an unlicensed band. The method, for performing wireless communication in an unlicensed band by a terminal, may include: receiving configuration information relating to a synchronization signal block (SSB) burst set in an unlicensed band; receiving transmission interval information in which an SSB is transmitted in the SSB burst set on the basis of a listen-before-talk (LBT) result with respect to the unlicensed band; and detecting the SSB in the SSB burst set on the basis of the transmission interval information.

說明書

In yet still another aspect, according to embodiments, there may be provided a base station performing wireless communication in an unlicensed band. The base station may include a controller performing a listen before talk (LBT) for a synchronization signal block (SSB) burst set in the unlicensed band and a transmitter transmitting configuration information about the SSB burst set in the unlicensed band and transmitting information about a transmission interval in which an SSB is transmitted in the SSB burst set based on a result of the LBT.

Advantageous Effects

According to embodiments, there may be provided a method and device for performing wireless communication in an unlicensed band to minimize the transmission/reception complexity of a synchronization signal block considering the results of an LBT upon transmitting a synchronization signal block for access in an unlicensed band.

Further, according to embodiments, there may be provided a method and device for performing beam estimation and applying an LBT-based beamforming pattern in an unlicensed band.
