1. A method for performing, by a first device, wireless communication, the method comprising:
selecting a first resource and a third resource within a selection window, based on sensing and resource selection procedure;
performing re-evaluation related to the first resource, based on triggering of the re-evaluation related to the first resource;
selecting a second resource, based on the re-evaluation related to the first resource;
transmitting, to a second device, sidelink control information (SCI) including a first value related to resource reservation period of the second resource, through a physical sidelink control channel (PSCCH), based on the second resource,
wherein the first value is determined equal to a second value related to resource reservation period of the third resource included within a first period, based on the second resource being included within the first period, and
wherein the first value is determined to be a value equal to the second value or different from the second value, based on the second resource being included within a second period after the first period; and
transmitting, to the second device, a medium access control (MAC) protocol data unit (PDU) through a physical sidelink shared channel (PSSCH), based on the second resource.
