    Abstract: The present disclosure provides a method for transmitting a random access channel (RACH) by a UE in a wireless communication system. Particularly, the method includes receiving information about actually transmitted synchronization signal blocks (SBBs) and RACH configuration information about RACH resources and transmitting a RACH in at least one RACH resource among RACH resources mapped to actually transmitted SSBs on the basis of the information about actually transmitted SSBs and the RACH configuration information, wherein the actually transmitted SSBs are repeatedly mapped to RACH resources by a positive integer multiple of the number of the actually transmitted SSBs in a RACH configuration period based on the RACH configuration information.

    Abstract: Disclosed are a method for transmitting and receiving a synchronization signal in a wireless communication system and an apparatus therefor. Specifically, a method for performing synchronization signal by transmitting and receiving a synchronization signal includes: receiving, from a base station, a primary synchronization signal (PSS) and a secondary synchronization signal (SSS); and performing synchronization by using the received PSS and the received SSS, in which a sequence for the SSS may be generated by a product between a first sequence and a second sequence and the number of first sequences may be configured to be larger than the number of second sequences.
