Abstract: Disclosed is a method of receiving a synchronization signal block (SSB) by a user equipment in a wireless communication system. The method includes receiving a first SSB from a serving cell, receiving a second SSB from a neighbor cell, obtaining time information of the first SSB based on a physical broadcasting channel (PBCH) included in the first SSB, and obtaining an index of the second SSB using the time information of the first SSB.

Abstract: The user equipment transmits a scheduling request by means of a scheduling request channel resource configured in the user equipment for beam recovery when uplink data is generated in the user equipment or when paging data is received therefor from a base station while the user equipment is in a discontinuous reception (DRX) mode. The user equipment receives an uplink grant in response to the scheduling request.

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: 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: Provided are methods and devices for transmitting/receiving downlink signals in a Wireless communication system. Carrier information is provided to user equipment, the carrier information including cell identifier information which indicates Whether a first cell identifier related to a first carrier operating on one resource block (RB) and a second cell identifier used for a cell-specific reference signal (CRS) on the first carrier are the same or different. If the second cell identifier is the same as the first cell identifier, the user equipment assumes that the number of antenna ports for the CRS on the first carrier is the same as the number of antenna ports for a reference signal defined for NB-IoT (reference signal for NB-IoT, NRS). If the second cell identifier is different from the first cell identifier, the carrier information further includes antenna port number information, and the user equipment assumes that the number of the antenna ports for the CRS is the same as the number of antenna ports based on the antenna port number information.

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.
