Abstract: Proposed is a method for performing wireless communication by a first device. The method may comprise a step of receiving a channel state information reference signal (CSI-RS) through a physical sidelink shared channel (PSSCH) from a second device, measuring a channel state through the CSI-RS on the basis of a reference type associated with the PSSCH, and transmitting information about the channel state to the second device. For example, the reference type associated with the PSSCH may be determined on the basis of whether a slot including a resource associated with the PSSCH includes a resource associated with a physical sidelink feedback channel (PSFCH).

A user equipment (UE) receives multiple PRACH configurations which include a first PRACH configuration for new radio access technology (NR) downlink/uplink (DL/UL) carrier in a NR band and a second PRACH configuration for a supplemental UL carrier in a long-term evolution (LTE) band, and transmits at least one of a first PRACH for accessing the NR DL/UL carrier in the NL band by using a first PRACH power based on the first PRACH configuration, or a second PRACH for accessing the supplemental UL carrier in the LTE band by using a second PRACH power based on the second PRACH configuration. The first PRACH configuration and the second PRACH configuration include different PRACH power configurations.

Abstract: Provided are a method and device for receiving remaining minimum system information (RMSI) in a wireless communication system. User equipment (UE) receives a synchronization signal (SS)/physical broadcast channel (PBCH) block from a network, receives information about an offset between the SS/PBCH block and the RMSI from the network, and receives the RMSI from the network on the basis of the information about the offset between the SS/PBCH block and the RMSI. The offset between the SS/PBCH block and the RMSI can be based on the numerology having a smaller subcarrier interval among the numerology of the SS/PBCH block and the numerology of the RMSI, and, more generally, the numerology having the smaller subcarrier interval among the numerology of the SS/PBCH block and the numerology of the RMSI can be the numerology having the smallest subcarrier interval in each frequency range (FR).

Abstract: Disclosed is a method for a terminal to receive a downlink signal from a base station in a wireless communication system. Specifically, the present invention may include: a step for acquiring a minimum CSI-RS triggering offset that is applicable to a CSI-RS for aperiodic CSI on the basis of the reception of a minimum applicable slot interval for the scheduling of a Physical Downlink Control Channel (PDCCH) and a Physical Downlink Shared Channel (PDSCH); a step for receiving, from the base station, downlink control information (DCI) for triggering the aperiodic CSI in a first slot; and a step for receiving the CSI-RS from the base station at a point in time later than the first slot and a second slot that is set on the basis of a CSI-RS triggering offset larger than or equal to the minimum applicable CSI-RS triggering offset.

Abstract: A method of performing an operation for a first user equipment (UE) in a wireless communication system includes determining a slot for transmitting a physical uplink control channel (PUCCH) based on a value related to the number of slots from a physical sidelink feedback channel (PSFCH) to the PUCCH by the first UE, and transmitting, to a base station (BS), feedback information based on the PSFCH through the PUCCH in the slot by the first UE. The value related to the number of slots is applied based on a last of slots for the PUCCH, overlapped with a slot for the PSFCH on a time axis.
