METHOD AND DEVICE FOR SELECTING PSFCH RESOURCE IN NR V2X

WIPO Patent Application WO/2021/071234

A1

A method by which a first device performs wireless communication is presented. The method can comprise the steps of: receiving a plurality of first physical sidelink control channels (PSCCHs); receiving a plurality of first physical sidelink shared channels (PSSCHs) related to the plurality of first PSCCHs; transmitting a plurality of second PSCCHs; transmitting a plurality of second PSSCHs related to the plurality of second PSCCHs; and performing any one related to a high priority from among the transmission of a plurality of first physical sidelink feedback channels (PSFCHs) and the reception of a plurality of second PSFCHs on the basis of a first priority of the transmission of a plurality of first PSFCHs related to the reception of the plurality of first PSSCHs and a second priority of the reception of a plurality of second PSFCHs related to the transmission of the plurality of second PSSCHs. For example: the first priority can be the highest priority from among a plurality of priorities related to the transmission of the plurality of first PSFCHs; the second priority can be the highest priority from among a plurality of priorities related to the reception of the plurality of second PSFCHs; and the transmission of the plurality of first PSFCHs and the reception of the plurality of second PSFCHs can overlap on a time domain.
