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: Disclosed herein is a method of transmitting a reference signal for channel state change measurement and an apparatus therefor. The method includes receiving, from a transmitter, a first type reference signal of a first resource mapping pattern and a second type reference signal of a second resource mapping pattern. The receiver receives the first type reference signal under an assumption that the first type reference signal is associated with the second type reference signal, when a specific condition is satisfied.

Abstract: A method for measuring a Synchronization Signal Block (SSB) by a terminal in a wireless communication system. In particular, the method may include: receiving a cell list including information of at least one first cell, first SSB transmission periodicity information for the at least one cell, and second SSB transmission periodicity information for a second cell that is not included in the cell list; measuring Reference Signal Received Power (RSRP) for an SSB of the at least one first cell based on a first SSB measurement window, which is set up by using the first SSB transmission periodicity information; and measuring RSRP for an SSB of the second cell based on a second SSB measurement window, which is set up by using the second SSB transmission periodicity information.

Abstract: A default subcarrier spacing for use in transmission/reception of a broadcast channel is defined for each frequency range. A base station transmits a broadcast channel in a frequency band, using the default subcarrier spacing defined for a frequency range to which the corresponding frequency band belongs. A user equipment attempts to detect a broadcast channel in the frequency band where a cell search is being attempted, using the default subcarrier spacing defined for a frequency range to which the frequency band belongs.

Abstract: A method for a user equipment to receive a PDCCH (Physical Downlink Control Channel) for RMSI (Remaining Minimum System Information). The method comprises: receiving an SS/PBCH block containing an SS (Synchronization Signal) and a PBCH (Physical Broadcasting Channel); obtaining information related to a CORESET (Control resource set) for the PDCCH; and receiving the PDCCH within the CORESET based on the information. The information includes an offset between a frequency position of the SS/PBCH block related to the CORESET and a frequency position of the CORESET. Values of the offset are defined based on subcarrier spacing of the SS/PBCH block and a minimum channel bandwidth.
