1. A method for performing wireless communication by a first device, the method comprising:
transmitting a first sidelink control information (SCI) including information related to a format of a second SCI to a second device through a physical sidelink control channel (PSCCH); and
transmitting the second SCI and data to the second device through a physical sidelink shared channel (PSSCH) related to the PSCCH,
wherein the information related to the format of the second SCI is determined based on whether location information of the first device is available,
wherein the format of the second SCI is different based on whether the second SCI includes a field related to distance-based hybrid automatic repeat request (HARQ) feedback based on a distance between user equipments (UEs), and
wherein, based on the location information of the first device being not available, the second SCI does not include the field related to the distance-based HARQ feedback.
