Abstract: The present disclosure discloses a method of receiving a synchronization signal block by a user equipment (UE) in a wireless communication system. The method includes receiving, in one of two half frames included in a frame, a synchronization signal block including a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcast channel (PBCH), and receiving a demodulation reference signal (DMRS) in a resource region carrying the PBCH. Information about the half frame in which the synchronization signal block is received may be obtained from a sequence of the DMRS.

Abstract: The present disclosure provides a method for receiving a synchronization signal block by a UE in a wireless communication system. Particularly, the method includes receiving at least one SSB mapped to a plurality of symbols, wherein two regions for candidate SSBs in which the at least one SSB can be received are allocated in a specific time duration including the plurality of symbols, and a time between the two regions, a time before the two regions and a time after the two regions are identical in the specific time duration.

Abstract: Disclosed is a method for transmitting a primary synchronization signal (PSS) by a base station in a wireless communication system. In particular, the method may comprise the steps of: dividing one symbol into multiple periods; generating multiple sequences for the PSS, the number of which is identical to the number of the multiple periods; and mapping the multiple sequences to the one symbol divided into the multiple periods, and transmitting the multiple sequences.

Abstract: A method of transmitting a synchronization signal block, which is transmitted by a base station in a wireless communication system, is disclosed in the present invention. The method includes the steps of mapping a synchronization signal block including a PSS (primary synchronization signal), an SSS (secondary synchronization signal), and a PBCH (physical broadcasting channel) to a plurality of symbols, and transmitting the synchronization signal block mapped to a plurality of the symbols to a user equipment. In this case, in a symbol mapped the PSS, in a symbol mapped the SSS, and in a symbol mapped the PBCH, centers of subcarriers to which the PSS, the SSS, and the PBCH are mapped are the same and the number of subcarriers to which the PBCH is mapped is greater than the number of subcarriers to which the PSS and the SSS are mapped.

Abstract: The present invention discloses a method of transmitting a Physical Random Access Channel (PRACH) by a terminal in a wireless communication system. Specifically, the method includes: receiving first information related to a Synchronization Signal Block (SSB) and second information related to PRACH resources; and transmitting the PRACH on a valid PRACH resource among the PRACH resources based on the first and second information. In this case, valid PRACH resource may be a PRACH resource allocated after symbols in which the SSB is received among the PRACH resources included in a PRACH slot related to the second information.
