Abstract: The present disclosure discloses a method for receiving a downlink signal by a UE in a wireless communication system. Particularly, the method may include receiving a synchronization signal block (SSB) including a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcasting channel (PBCH), and obtaining an indicator indicating a subcarrier spacing for the downlink channel from the PBCH, and receiving the downlink signal on the basis of the subcarrier spacing. The indicator may indicate a different subcarrier spacing according to a frequency band in which the UE operates.

Abstract: There is provided an apparatus for supporting a new radio technology unlicensed (NR-U) based cell. The apparatus may comprise: at least one processor; and at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed by the at least one processor, perform operations. The operations may comprise: receiving at least one synchronization signal block (SSB) from the NR-U based cell; and performing a synchronization with the NR-U based cell, based on the received at least one SSB. A frequency position of the SSB may be defined by a synchronization raster. The synchronization raster may exist at every 20 MHz in a NR-U band, based on that the NR-U based cell operates in a channel bandwidth greater than 20 Mhz.

Abstract: The present invention discloses a method for transmitting and receiving signals between a user equipment and a base station in a wireless communication system and device for supporting the same. More specifically, the invention discloses a method by which, when a base station transmits synchronization signal blocks in various beam directions, a user equipment achieves synchronization with the base station by detecting the index of a received synchronization signal block and then transmits and receives signals with the base station.

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 invention discloses a method for obtaining information for a cyclic prefix (CP) in a wireless communication system by a terminal and a device for the same. Specifically, a method for obtaining information for a cyclic prefix (CP) in a wireless communication system by a terminal includes: detecting a specific synchronization signal received from a base station via a first symbol of a first subframe; detecting the specific synchronization signal received from the base station via a second symbol of a second subframe; and obtaining information for the CP applied to transmission of the specific synchronization signal based on an offset value between an index of the first symbol and an index of the second symbol.

Abstract: A user equipment receives a first multiple access (MA) time resource information indicating static MA time resources in which uplink (UL) grant-free UL transmission is permitted among time resources corresponding to a fixed time length Twindow. If UL data (hereafter referred to as first UL data) to be transmitted in one (hereafter referred to as a first static MA time resource) of the static MA time resources exists, the UE transmits the first UL data in the first static MA time resource by means of a predetermined frequency resource. The UE can monitor downlink control information (hereafter referred to as first DCI) in non-static MA time resources, which are not the static MA time resources, among the time resources, and, if the first DCI is received, can transmit UL data (hereafter referred to as second UL data) to the first DCI or receive DL data.
