METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING WIRELESS SIGNAL IN WIRELESS COMMUNICATION SYSTEM

WIPO Patent Application WO/2021/029737

A1

The present invention relates to a wireless communication system and, particularly, to a method comprising the steps of: receiving information related to interval Q between SS/PBCH blocks in a QCL relationship in an unlicensed band, through a PBCH; and estimating a downlink path loss for uplink transmission on the basis of a plurality of SS/PBCH blocks having the same modulo (X, Q) value as a specific SS/PBCH block index within a time window in the unlicensed band, and an apparatus therefor.
