摘要： 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.

摘要： 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.

摘要： 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.

摘要： The present invention provides a method for a terminal and a base station including multiple TRPs to transmit/receive signals, and a device therefor. More particularly, the present invention provides a method whereby, if one or more base stations are present, and multiple TRPs are present in each of the base stations, a TRP for signal transmission/reception by a terminal and a base station is selected by using an uplink signal transmitted by the terminal, and a signal is transmitted/received based on the TRP. The present invention also provides a device for the method.

摘要： Disclosed are methods for transmission and reception of downlink control information between a base station and a terminal, and devices for supporting same. Disclosed more particularly are: methods whereby a base station transmits downlink control information by means of an analogue beam independently determined for every one or more symbols (e.g., a unit of one or more symbols) and, in response to the base station, a terminal receives, by means of a serving beam of the terminal, the downlink control information transmitted by means of the analogue beam, which corresponds to the serving beam; and devices for supporting same.
