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).

Abstract: The present disclosure relates to transmission prioritization in wireless communications. According to an embodiment of the present disclosure, a method performed by a wireless device in a wireless communication system comprises: configuring a threshold; creating a media access control (MAC) protocol data unit (MAC PDU) for sidelink comprising a MAC control element (CE); setting a priority value to the MAC CE; identifying a transmission of the MAC PDU for sidelink and an uplink transmission to be performed; determining that the transmission of the MAC PDU for sidelink and the uplink transmission are not able to be performed simultaneously; determining that the priority value of the MAC CE is lower than the threshold; prioritizing the transmission of the MAC PDU for sidelink over the uplink transmission; and performing the transmission of the MAC PDU for sidelink that is prioritized over the UL transmission.

Abstract: According to the present invention, a common control signal via a group common control channel (GCCC) for a new radio access technology (NR) is defined. A user equipment (UE) receives the common control signal from a network via GCCC. The common control signal is for all UEs or a group of UEs in a cell. The UE handles the priority of the common control signal compared to other signals. For example, the priority of the common control signal may be higher than a semi-static UE-specifically configured configuration, and may be lower than a cell-commonly or group-commonly configured configuration.
