Method and apparatus for measuring synchronization signal in wireless communication system

A terminal comprising a processor,

• wherein the processor causes the terminal to perform:
• receiving, from a base station, radio resource control (RRC) signaling including measurement gap configuration information (MeasGapConfig) including gap setup information (gapSAT) of synchronization signal blocks (SSBs);
• obtaining transmission position information of first SSBs and second SSBs transmitted from different positions based on gap configuration (GapConfig) of the gap setup information;
• receiving the first SSBs and the second SSBs through different beams from the base station based on the obtained transmission position information;
• and
• measuring reception powers of the received first SSBs and second SSBs.

A method of a base station, comprising:

• transmitting, to a terminal, radio resource control (RRC) signaling including measurement gap configuration information (MeasGapConfig) including gap setup information (gapSAT) of synchronization signal blocks (SSBs);
• transmitting first SSBs and second SSBs through beams respectively corresponding to a plurality of spatially separated regions, based on the measurement gap configuration information;
• and
• receiving a reception power for at least one SSB among the first SSBs or the second SSBs from the terminal,
• wherein a gap configuration (GapConfig) included in the gap setup information includes transmission position information of the first SSBs and the second SSBs transmitted in different positions within an SSB measurement gap repetition periodicity (MGRP).
