Method for transmitting and receiving signal in wireless communication system, and device supporting same
The various embodiments relate to a method carried out by a terminal in a wireless communication system, and a device supporting same, where first and second information is received, and the first information relates to a time domain position of a transmitted synchronization signal/physical broadcast channel (SS/PBCH) block among a plurality of candidate SS/PBCH blocks and the second information relates to a quasi co-location (QCL) relationship for the transmitted SS/PBCH block. A physical downlink shared channel (PDSCH) based on the first information and the second information is obtained; however, it is specifically obtained in a resource region in which the resource for the PDSCH and a resource for a candidate SS/PBCH block which does not have a QCL relationship with the transmitted SS/PBCH block overlap with each other.
