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 for performing wireless communication by a first device and a device for supporting same are provided. The method may include receiving, from a second device, a Physical Sidelink Control Channel (PSCCH) and a Physical Sidelink Shared Channel (PSSCH), based on information on a first transmission power for the PSCCH and the PSSCH, included in the PSCCH or the PSSCH, determining a first Reference Signal Received Power (RSRP) of a DM-RS (Demodulation-Reference Signal) received through the PSSCH, and performing sidelink communication based on the determined first RSRP. For example, the information on the first transmission power is based on a maximum transmission power and an allowable threshold.

Abstract: Provided are a method for managing a beam performed by a terminal in a wireless communication system and a device using the method. According to the method, the terminal performs a power saving operation on a first cell and receives a PDCCH through a second cell, wherein the PDCCH requests to measure a reference signal transmitted aperiodically in the first cell. The reference signal is received at a particular time for a DRX cycle related to the power saving operation. The terminal generates beam related information to be used in the first cell by measuring the reference signal in the first cell.
