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 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: In the present invention, a part of a first demodulation reference signal sequence generated on the basis of a basic subcarrier interval (hereinafter, a first subcarrier interval) is used for a second subcarrier interval which is K times the first subcarrier interval. Values selected one for every K from among values constituting the first demodulation reference signal sequence may be used as values constituting a second demodulation reference signal sequence for the second subcarrier interval.

Abstract: A method for user equipment (UE) to receive a reference signal in a cellular mobile communication system supporting narrowband Internet of Things (NB-IoT) is disclosed. To this end, the UE receives, via at least one first subframe, a narrowband reference signal (NRS) for signal demodulating or measurement in NB-IoT and receiver, via at least one second subframe, a narrowband positioning reference signal (NPRS) for location-based measurement in the NB-IoT, wherein information on the at least one second subframe is received from a base station as configuration information of the NPRS, and, in accordance with the configuration information of the NPRS, the UE operates by assuming that the NRS is not transmitted in a subframe configured with the second subframe.
