    Abstract: Systems and methods disclosed herein describe the use of synchronization signal/physical broadcast channel block measurement time configuration (SMTC) 2 low power (SMTC2-LP) configuration(s). For cell measurements, a UE may determine that an SMTC2-LP configuration for one or more carriers of one or more target cells is known, determine a periodicity of SMTC occasions of the carrier(s) based on data found in the SMTC2-LP configuration(s), and cancel a cell measurement of an inter-frequency cell based at least in part on the periodicity of the SMTC occasion(s). For cell re-selection, a UE may determine that an SMTC2-LP configuration for a carrier being used at a target cell is known and that a physical cell identity (PCI) of the target cell is found in data of the SMTC2-LP configuration, determine a maximum paging interruption time using this periodicity, and perform a cell reselection to the target cell within this time.

    Abstract: Systems and methods for utilizing inter-UE coordination regarding reserved resources of a sidelink (SL) resource pool are described herein. A first user equipment (UE) may identify that a first SL resource pool on a first radio access technology (RAT) overlaps with a second SL resource pool on a second RAT, sense for reservation signaling on the second SL resource pool to determine reserved resources on the second SL resource pool, and transmit resource reservation information indicating those reserved resources on SL on the first RAT. A second UE may receive the resource reservation information on the SL, identify, within the first SL resource pool, corresponding resources that overlap with the reserved resources of the second SL resource pool, select, from the first SL resource pool, transmission resources to use for a SL transmission by prioritizing resources other than the corresponding resources; and perform the SL transmission using those transmission resources.

    Abstract: Systems and methods for user equipment (UE) capable of performing sidelink (SL) communications that account for overlapped SL resource pools of multiple radio access technologies (RATs) are disclosed. A UE may select, based on prioritizing non-overlapped resources over overlapped resources, one or more candidate resources and/or one or more transmission resources; may determine a power control configuration without considering SL pathloss corresponding to a first RAT when a second power control configuration determination for a second RAT does not consider SL pathloss; may select physical sidelink feedback channel (PSFCH) locations for PSFCH use from first PSFCH locations of resources of a first SL resource pool on a first RAT that do not overlap with a second SL resource pool on a second RAT according to a bitmap; and/or may select one of a PSFCH transmission and PSFCH reception using a data priority rule and/or a pool sharing rule.
