A user equipment, comprising a processor configured to:
- determine a subset of resources from which a MAC layer select for a physical sidelink shared channel/physical sidelink control channel (PSSCH/PSCCH) transmission as part of a re-evaluation or a pre-emption in a slot n for partial sensing if Prsvp_TX≠0, where Prsvp_TX is a resource reservation interval provided by the MAC layer, wherein the MAC layer provides resources subject to the re-evaluation or the pre-emption;
- and
- determine a first candidate slot of the re-evaluation or the pre-emption as a first slot among slots of
