    Abstract: Provided are a method for performing wireless communication by a first device and an apparatus supporting same. The method may comprise: transmitting, to a second device through a physical sidelink control channel (PSCCH), a first sidelink control information (SCI) including information related to a physical sidelink feedback channel (PSFCH) overhead and a beta offset; and transmitting, to the second device through a physical sidelink shared channel (PSSCH) related to the PSCCH, a second SCI, wherein a symbol length related to the PSSCH is obtained based on the information related to the PSFCH overhead, and wherein a number of resource elements (REs) to which the second SCI is mapped is obtained based on the symbol length related to the PSSCH and the beta offset.

    Abstract: A method for a first device to perform wireless communication is proposed. The method may comprise: receiving at least one physical sidelink control channel (PSCCH); receiving at least one physical sidelink shared channel (PSSCH) related to the at least one PSCCH; determining a resource related to at least one physical sidelink feedback channel (PSFCH) based on an index of a slot and an index of a subchannel related to at least one PSSCH; determining N PSFCHs from among the at least one PSFCH based on a sum of power required to transmit the at least one PSFCH being greater than a maximum transmit power of the first device, wherein N is selected from a number of PSFCH transmissions with high priority among a maximum number of PSFCH transmissions, to the maximum number of the PSFCH transmissions.

    Abstract: Provided are a method by which a first apparatus performs wireless communication, and an apparatus supporting same. The method may comprise the steps of: receiving, via a first physical sidelink control channel (PSCCH), first sidelink control information (SCI) including information related to a plurality of sidelink (SL) resources which have been reserved by a second apparatus; receiving, via a second PSCCH, second SCI including information related to a plurality of SL resources which have been reserved by a third apparatus, wherein a first SL resource from among the plurality of SL resources which have been reserved by the second apparatus overlaps a second SL resource from among the plurality of SL resources which have been reserved by the third apparatus; determining a physical sidelink feedback channel (PSFCH) resource related to the first SL resource and the second SL resource; and transmitting, to the second apparatus or the third apparatus, information related to the overlap, on the basis of the PSFCH resource.
