Abstract: A method and apparatus for transmission based on QoS requirement in a wireless communication system is provided. A wireless device sets a priority level of a logical channel. A wireless device detects that Quality of Service (QoS) requirement of the logical channel is not met. A wireless device de-prioritizes the priority level of the logical channel. A wireless device performs the SL transmission and/or the UL transmission for the logical channel with the de-prioritized priority level.

Abstract: Proposed is a method for performing wireless communication by a first device. The method may comprise the steps of: receiving a plurality of sidelink-synchronization signal blocks (S-SSBs) from a plurality of synchronization sources, wherein each of the plurality of S-SSBs includes a sidelink primary synchronization signal (S-PSS), a sidelink secondary synchronization signal (S-SSS), and a physical sidelink broadcast channel (PSBCH); selecting any one of the plurality of synchronization sources on the basis of a reference signal received power (RSRP) associated with each of the plurality of S-SSBs and a sidelink synchronization signal (SLSS) ID associated with each of the plurality of S-SSBs; performing synchronization on the basis of the S-SSB associated with the selected synchronization source; and transmitting a PSCCH or PSSCH to a second device on the basis of the synchronization. For example, the SLSS ID associated with each of the plurality of S-SSBs may be a criterion for selecting any one of the plurality of synchronization sources, on the basis of the fact that a RSRP value associated with each of the plurality of S-SSBs is greater than or equal to a minimum RSRP threshold value.
