Abstract: The present disclosure provides a method for receiving a channel state information-reference signal (CSI-RS) by a UE in a wireless communication system. Particularly, the method includes receiving information on a measurement bandwidth and cell list information for a plurality of cells, receiving CSI-RSs of the plurality of cells, and measuring reception power for the CSI-RSs within the measurement bandwidth, wherein sequences of the CSI-RSs are mapped to physical resources based on the same reference position configured by a higher layer.

Abstract: The present disclosure discloses a method of receiving a downlink channel by a user equipment (UE) in a wireless communication system. Particularly, the method includes receiving a synchronization signal block (SSB) including a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcast channel (PBCH), obtaining information about the position of a downlink bandwidth from the PBCH, and receiving the downlink channel within the downlink bandwidth determined on the basis of the obtained information about the position of the downlink bandwidth. The information about the position of the downlink bandwidth is an offset from the position of a bandwidth of the SSB to the position of the downlink bandwidth.

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, when a UE transmits a random access preamble, the UE maintains a power ramping counter used for determination of a transmission power equally to a value of previous transmission without incrementing the power ramping counter if a target synchronization signal block is changed differently from a previous random access preamble transmission.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for reporting CSI in a wireless communication system, the method comprising: a step for configuring a plurality of serving cells; and a step for reporting the CSI of only one serving cell in a corresponding subframe, wherein the step for reporting the CSI of only one serving cell comprises: excluding reporting the CSI of a lower priority when CSI reports of the plurality of serving cells in the corresponding subframe collide; and excluding reporting the CSI of serving cells other than the serving cell having the smallest index when the CSI reports of different serving cells having the same priority in the corresponding subframe collide.

Abstract: A user equipment (UE) receives UE group information indicating a first UE group to which the UE belongs, and transmits uplink (UL) data and a demodulation reference signal (DM-RS), which is for demodulating the UL data, on the basis of the UE group information. The DM-RS is transmitted by means of a first uplink demodulation reference signal (UL DM-RS) resource, which corresponds to the first UE group to which the UE belongs, among a plurality of UL DM-RS resources respectively corresponding to one or more UE groups.

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: The present invention discloses a method for a user equipment to receive a PDCCH (Physical Downlink Control Channel) for RMSI (Remaining Minimum System Information). The method comprises: receiving an SS/PBCH block containing an SS (Synchronization Signal) and a PBCH (Physical Broadcasting Channel); obtaining information related to a CORESET (Control resource set) for the PDCCH; and receiving the PDCCH within the CORESET based on the information. The information includes an offset between a frequency position of the SS/PBCH block related to the COPRESET and a frequency position of the CORESET. Values of the offset are defined based on subcarrier spacing of the SS/PBCH block and a minimum channel bandwidth.
