    Abstract: A method of performing, by a user equipment (UE), a sidelink communication in a wireless communication system is disclosed. More specifically, the method comprises receiving a sidelink-synchronization signal block (S-SSB) from other UE; performing a synchronization with the other UE based on the S-SSB; and receiving (i) a physical sidelink control channel (PSCCH) and (ii) a physical sidelink shared channel (PSSCH) based on a result of the synchronization. The S-SSB includes information on a type of the other UE, and the result of the synchronization is determined based on (i) the information on the type of the other UE and (ii) a type of the UE.

    Abstract: A method for performing, by a first device, wireless communication and an apparatus for supporting same are provided. The method includes: receiving a physical sidelink shared channel (PSSCH) from a second device; determining a physical sidelink feedback channel (PSFCH) resource associated with the PSSCH; and transmitting, to the second device, a hybrid automatic repeat request (HARQ) feedback on the PSFCH resource. Here, at least one subchannel for the PSSCH is associated with at least one first PSFCH resource including at least one second PSFCH resource, each second PSFCH resource included in the at least one first PSFCH resource is associated with each slot on the at least one subchannel, and the PSFCH resource may be determined on the basis of information related to the at least one subchannel for the PSSCH, information related to at least one slot for the PSSCH, and a source ID of the second device.

    Abstract: Provided are a method for performing wireless communication by a first device and a device supporting same. The method may comprise the steps of: configuring information on a first sidelink (SL) priority threshold value associated with a first radio access technology (RAT); configuring information on a second SL priority threshold value associated with a second RAT; configuring information on a third SL priority threshold value; and on the basis that uplink (UL) transmission and SL transmission overlap each other in a time domain, performing prioritization for the UL transmission and the SL transmission. For example, on the basis that RATs of the UL transmission and the SL transmission are different, the prioritization for the UL transmission and the SL transmission may be performed on the basis of the third SL priority threshold value.
