Abstract: Systems and methods for sidelink (SL) resource pool resource use by a user equipment (UE) are disclosed herein. In some embodiments, when the UE performs contiguous partial sensing in addition to periodic partial sensing, the UE performs one of resource selection and resource re-evaluation based a size of a time gap between a slot where the UE has SL data and a first slot of periodic-based candidate slots within a resource selection window. In other embodiments, the UE performs contiguous partial sensing without additional periodic partial sensing in the case where a packet delay budget (PDB) for the SL data is greater than a threshold. In some embodiments, the UE performs periodic partial sensing for resource re-evaluation and/or resource pre-emption according to a set of periodicity values Preserve,re-ev (and optionally period definition data Kre-ev). Restrictions on the use of random resource selection by the UE are also described.

Abstract: Systems and methods provide for physical downlink control channel (PDCCH) monitoring adaptation. A user equipment (UE) may monitor a default search space set group (SSSG) for downlink control information (DCI) from a base station in the PDCCH. In response to a first DCI trigger, the UE switches from monitoring the default SSSG to monitoring a first non-default SSSG associated with a first timer. In response to a second DCI trigger, the UE switches from monitoring the first non-default SSSG to monitoring a second non-default SSSG associated with a second timer. The first non-default SSSG may be a non-empty SSSG including a search space set with at least one associated search space. The second non-default SSSG may be an empty SSSG with no associated search space to emulate PDCCH skipping.
