Abstract: A method of a user equipment (UE) performing cell re-selection in New Radio (NR) unlicensed (NR-U) idle mode includes performing cell re-selection associated with a selected public land mobile network (PLMN) in New Radio (NR) unlicensed (NR-U) idle mode. Performing cell re-selection in NR-U idle mode further comprises determining a best cell associated with the selected PLMN based on one or more measurements. At least one of the one or more measurements may comprise a channel occupancy measurement. Performing cell re-selection in NR-U idle mode further comprises camping on the best cell and periodically searching for cells that are determined to be better than the best cell based on the one or more measurements.

Abstract: A UE may estimate the power headroom value when using shortened Transmission Time Intervals (sTTI). In one implementation, the power headroom value may be calculated based on an estimation of the UE transmission power over two or seven OFDM symbols. Alternatively or additionally, the power headroom value may be calculated based on an estimation of the UE transmission power over the period of an sTTI. Alternatively or additionally, the power headroom value may be calculated based on an average of the UE transmission power over multiple sTTI periods in a subframe. Alternatively or additionally, the power headroom value may be calculated based on a maximum or minimum of the UE transmission power measured over multiple sTTI periods in a subframe. Alternatively or additionally, the power headroom value may be calculated based on UE transmission power measured in the first or the last sTTI period in a subframe.

Abstract: The present application relates to devices and components including apparatus, systems, and methods to provide DRX groups for licensed and unlicensed bands. For example, a first DRX group can be used in association with an NR licensed band of FR1, a second DRX group can be used in association with NR-U of FR1, and a third DRX group can be used in association with FR2. In this way, power savings of DRX groups can be granular to the level of licensed and unlicensed bands.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE) and/or cellular network to perform downlink control information (DCI) mode signaling and control resource set (CORESET) selection. A DCI mode may be signaled based on a predefined rule, media access control (MAC) control element (CE), and/or group based beam reporting. One or more CORESETs may be selected based on configuration of an active bandwidth part (BWP), CORESET identifier, higher layer index, periodicity, type of search space, and/or MAC CE.

Abstract: Beamforming measurement techniques based on PSS/SSS are disclosed. An apparatus of a user equipment (UE) can include processing circuitry configured to decode a configuration message from a source serving cell, the configuration message indicating signal selection criteria for cell measurement reporting. A synchronization signal (SS) burst set associated with one or more transmission/reception points (TRPs) within a neighboring cell is decoded, the SS burst set including a plurality of SS blocks. A cell beamforming measurement signal associated with the neighboring cell is generated, based on signal measurements of the SS blocks and the signal selection criteria. A radio resource management (RRM) measurement report message is encoded for transmission to the serving cell, the measurement report message including the cell beamforming measurement signal. A handover command message for initiating a handover to the neighboring cell is decoded, the handover command based on the cell beamforming measurement signal.

Abstract: Embodiments of the present disclosure describe methods, apparatuses, storage media, and systems for adequately measuring reference signals while a user equipment (UE) uses beamforming for optimal receiving. Embodiments describe how a UE may measure received-beamformed reference signals as well as how to determine a reported value while multiple beams are measured or a receiver diversity is in use by the UE. Other embodiments may be described and claimed.

Abstract: In embodiments, a UE may measure system frame number (SFN)/subframe timing differences between a master eNB (MeNB) and secondary eNB (SeNB) for dual connectivity (DC). When network-based reporting on the SFN/subframe timing offset is used, no new radio access network (RAN) signaling may be needed. However, in the case of multi-vendor deployments, no network coordination via different Operations, Administration, and Maintenance (OAM) for DC may occur. In this case, the network may not be able to obtain SFN/subframe timing offset information. To address this issue, various embodiments disclosed herein include UE-based reporting on SFN/subframe offset between an MeNB and an SeNB.

Abstract: Systems and methods provide for beam detection in a wireless communication system. An apparatus for a UE may be configured to identify a plurality of CSI-RS resources corresponding to different Tx beams configured for measurement by the UE, measure an L1-RSRP for the plurality of CSI-RS resources, determine a selected Tx beam of the different Tx beams based on measured L1-RSRP values for the plurality of CSI-RS resources, and determine a measurement accuracy of a first L1-RSRP value corresponding to the selected Tx beam based on successful beam detection probability.
