Abstract: Provided herein are a method for performing wireless communication by a first apparatus and an apparatus for supporting the same. The method may include the steps of receiving a configuration related to a Uu bandwidth part (BWP) from a base station, and receiving a configuration related to a sidelink (SL) BWP from the base station. Herein, based on a numerology of the Uu BWP and a numerology of the SL BWP being different, the first apparatus may not perform SL communication on the SL BWP.

Abstract: A method of transmitting an uplink (UL) signal by a user equipment (UE) in a wireless communication system, where the method includes: receiving, through a physical downlink control (PDCCH) signal, downlink control information (DCI) regarding a semi-persistent scheduling (SPS) physical uplink shared channel (PUSCH); and periodically transmitting an SPS PUSCH signal based on the DCI. Periodically transmitting the SPS PUSCH signal based on the DCI includes: in a state in which (i) the SPS PUSCH signal is subslot-based, (ii) a demodulation reference signal (DMRS) pattern field included in the DCI is set to a first value, and (iii) simultaneous transmission of a physical uplink control channel (PUCCH) and the PUSCH is configured for the UE: transmitting uplink control information (UCI) through the SPS PUSCH signal, without simultaneously transmitting a PUCCH signal.
