Abstract: A method of receiving remaining minimum system information (RMSI) by a user equipment (UE) in a wireless communication system is disclosed. The method includes receiving a synchronization signal/physical broadcast channel (SS/PBCH) block in a specific band, obtaining a size of a synchronization raster for the specific band based on the SS/PBCH block, and receiving the RMSI based on the size of the synchronization raster.

Abstract: Provided is a communication method for interference avoidance in an unlicensed band. A transmission node transmits in the unlicensed band a preemption signal to a target reception node. Upon receiving a ready signal from the target reception node, the transmission node transmits in the unlicensed band a data signal to the target reception node. The preemption signal is transmitted by means of a narrow beam having substantially the same width and direction as the data signal.

Abstract: The present invention discloses a method for a terminal to receive a synchronization signal in a wireless communication system. Particularly, the method includes the steps of receiving a synchronization block including a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcasting channel (PBCH) and receiving a DMRS (demodulation reference signal) via resource region in which the PBCH is received. In this case, an index of the synchronization block can be determined in consideration of a sequence of the DMRS.

Abstract: The present disclosure provides a method for performing channel estimation using a demodulation reference signal (DMRS) in a wireless communication system. More specifically, the method, which is performed by a base station, comprises: when a collision between a DMRS symbol and a synchronization signal block (SSB) occurs, shifting a resource block (RB) of the DMRS symbol where the collision occurs, and all REs bundled with the RE of the DMRS symbol where the collision occurs; transmitting information on the shifted REs to a terminal; and transmitting the DMRS to the terminal on the shifted REs.

Abstract: According to one embodiment of the present disclosure, a method and an apparatus for allowing a user equipment (UE) to effectively monitor a control resource set (CORESET) in order to read remaining minimum system information (RMSI) in a wireless communication system are provided. The UE receives a media access control (MAC) control element (CE) indication, performs a random access channel (RACH) procedure, determines a transmission configuration indicator (TCI) state of CORESET 0 on the basis of the most recent of either the MAC CE indication or the RACH procedure, and monitors CORESET 0 on the basis of the determined TCI state.

Abstract: Provided are a method for reporting a power headroom and an apparatus using the same. The apparatus computes and reports a power headroom for a physical uplink shared channel (PUSCH) that is transmitted in a first transmission period of a first band having a first subcarrier interval. The power headroom is computed on the basis of at least one second transmission interval of a second band having a second subcarrier interval which overlaps with the first transmission interval.

Abstract: Disclosed herein are a method and apparatus for transmitting/receiving random access signals. A user equipment (UE) transmits a random access preamble of a random access procedure through a random access channel (RACH) resource associated with a synchronization signal (SS) block. A base station (BS) receiving the random access preamble from a UE can transmit CSI-RSs to the UE. The BS may inform the UE that there will be CSI-RS transmission to the UE, during the random access procedure.
