1. An apparatus for a user equipment (UE), the apparatus comprising:
processing circuitry, wherein to configure the UE for Fifth Generation New Radio (5G-NR) sidelink communications, the processing circuitry is to:
determine a sidelink control information (SCI) format, the SCI format received via a physical sidelink control channel (PSCCH), and the SCI format including priority information for a scheduled physical sidelink shared channel (PSSCH) transmission;
determine first configuration information and second configuration information using configuration signaling, the first configuration information identifying a sensing window, and the second configuration information identifying a resource selection window, wherein a boundary of the resource selection window is based on the priority information;
determine during the sensing window, a set of candidate single-slot resources from a resource pool;
select during the resource selection window, a resource from the set of candidate single-slot resources;
encode control information for a sidelink transmission;
cause the sidelink transmission via the PSCCH, the sidelink transmission using the resource;
encode a resource reservation for a PSCCH transmission in a second SCI format, the resource reservation indicating N resources from a set of resources selected by higher layers with N smallest slot indices; and
cause the PSCCH transmission of the second SCI format; and
memory coupled to the processing circuitry.
