Systems and methods for new radio sidelink procedures in unlicensed spectrums

Abstract

A system and a method are disclosed for multi-slot resource reservations in new radio (NR) sidelink (SL) using the unlicensed spectrum. Embodiments include determining, by an NR user equipment (UE), a multi-slot reservation configuration, wherein the multi-slot reservation configuration comprises a plurality of reservation slots corresponding to a time domain and frequency domain; performing, by the NR UE, a listen-before-talk (LBT) operation; and in response to LBT operation, indicating, by the NR UE, a selection of a plurality of multi-slot resources in the time domain and the frequency domain on which to transmit one or more signals, the plurality of multi-slot resources corresponding to the plurality of reservation slots of the multi-slot reservation configuration. Embodiments further include updates to Mode 2 signaling including the plurality of multi-slot resources is further based on an evaluation of a high-layer parameter, and/or selecting a single-candidate resource slot, based on consecutive subsequent slots.
