1. One or more non-transitory computer-readable media (NTCRM) having instructions, stored thereon, that when executed by one or more processors of a user equipment (UE) configure the UE to:
receive configuration information for physical downlink control channel (PDCCH)-based paging early indication (PEI) for use by the UE while the UE is in an idle state or an inactive state, the configuration information for the PDCCH-based PEI including a PEI-radio network temporary identifier (RNTI); and
monitor paging occasions for a PDCCH in a common search space based on the configuration information for the PDCCH-based PEI,
wherein the configuration information for the PDCCH-based PEI indicates: one or more paging subgroups, whether paging occasions associated with a respective one or more of the paging subgroups are to be monitored by the UE, and for the paging subgroups that are to be monitored by the UE, respective tracking reference signal (TRS) resources that are indicated to be present during corresponding ones of the paging occasions, and
wherein the UE is configured to use the respective TRS resources that are indicated to be present during corresponding ones of the paging occasions while the UE is in the inactive or idle state for paging reception mode prior to a paging occasion that is to be monitored.
