Abstract: Disclosed are a method whereby user equipment operates in a wireless communication system, and a device for supporting same. Disclosed more particularly are: a method whereby, in case a base station which operates multiple analogue beams is connected to user equipment, the user equipment determines a cell-level radio link failure (RLF) and a beam-level RLF through signal transmission and reception to and from the base station and carries out an operation based on the determination; and a device for supporting said method.

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.
