Method for transmitting/receiving signal in wireless communication system, and device supporting same

1. A method performed by a user equipment (UE) configured to operate in a wireless communication system, the method comprising:

receiving a synchronization signal/physical broadcast channel (SS/PBCH) block among a plurality of SS/PBCH blocks; and

acquiring synchronization based on the SS/PBCH block,

wherein the SS/PBCH block comprises a primary synchronization signal (PSS), a secondary synchronization signal (SSS) and a physical broadcast channel (PBCH),

wherein a plurality of candidate SS/PBCH blocks related to the plurality of SS/PBCH blocks are included in a half frame, and

wherein information related to quasi-co-located (QCL) relation between the plurality of SS/PBCH blocks is received through a system information block (SIB) 4.

2. The method of claim 1 , wherein the information related to QCL relation indicates one of: 1, 2, 4 or 8.

3. The method of claim 1 , wherein the information related to QCL relation being received through the SIB4 corresponds to cell re-selection.

4. The method of claim 1 , wherein an index of the SS/PBCH block is determined based on the information related to QCL relation and the plurality of candidate SS/PBCH blocks.

5. The method of claim 1 , wherein a number of the plurality of candidate SS/PBCH blocks and a number of bits included in the PBCH are determined based on a subcarrier spacing (SCS) for the plurality of SS/PBCH blocks.
