    Abstract: A user equipment (UE) is served by a serving cell of a network and is configured to measure channel state information reference signals (CSI-RS) from a target cell. The UE receives, from the serving cell, a measurement configuration message indicating the UE is to measure CSI-RS from a target cell of the network, wherein the measurement configuration message does not include Synchronization Signal Block (SSB) information for the target cell but further comprises an indication of whether the target cell transmits SSBs. The UE determines, based on at least the measurement configuration message, a time and frequency resource on which the CSI-RS of the target cell are to be transmitted and measures the CSI-RS of the target cell.

    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: A user equipment (UE) is connected to a 5G New Radio (NR) network via a serving cell. The UE performs radio resource management (RRM) measurements on the serving cell, determines whether the UE satisfies power saving criteria for a first, second, or third mobility scenario while in a Radio Resource Control (RRC) idle state or RRC inactive state, wherein, when the UE is in the first or second mobility scenario, the UE performs RRM measurements with longer intervals relative to RRM measurements performed in a non-power-saving mode and wherein, when the UE is in the third scenario, the UE performs RRM measurements for neighbor cells with longer intervals relative to RRM measurements performed in a non-power-saving mode and determines a UE RRM configuration when the UE transitions from any of the power saving scenarios or the non-power-saving mode to any other power saving scenarios or the non-power-saving mode.

    Abstract: Techniques discussed herein facilitate generation of uplink control information for Enhanced Physical Uplink Control Channel (PUCCH) Format (s) (EPF (s) ). One example embodiment employable in a User Equipment (UE) is configured to: determine Hybrid Automatic Repeat reQuest-Acknowledgment (HARQ-ACK) information; generate a PUCCH for a BandWidth Part (BWP) based at least in part on the HARQ-ACK information, wherein the PUCCH has an EPF; determine a PUCCH resource for the PUCCH and a first PRB index for the PUCCH, wherein the PUCCH resource is determined based at least in part on an index of a first Control Channel Element (CCE) of an associated Physical Downlink Control Channel (PDCCH) and a number of CCEs in a Control Resource Set (CORESET) of the associated PDCCH; and map the PUCCH to at least one PUCCH interlace based on the PUCCH resource and the first PRB index for the PUCCH.
