    Abstract: Measurement modeling and filtering may include configurable cell quality derivation method is used for multi-beam based NR networks; a common measurement model that considers different characteristics of the two measurement signals, NR synchronization signal and additional reference signal; and a multi-level measurement filtering approach that handles different mobility scenarios in an NR network. Measurement configuration and procedures may include a measurement gap design during which UE may use to perform measurements for beam sweeping based NR networks; a group of triggering events that may be used to trigger UE mobility management in an NR network; a content format that may be used for the transmission of UE measurement report; a measurement object design (the object on which a UE may perform the measurements) to reduce UE measurement overhead and cost; and a downlink measurement based inter-cell handover procedure that may be used in an NR network.

    Abstract: Downlink Control Information (DCI) may be expanded, or enhanced, to allow nodes such as UEs, eNBs, NR-nodes, gNBs, and TRPs in M2M, IoT, WoT networks to coordinate activities on PHY, MAC, and RRC layers. For example, DCI fields may be added or enhanced to include, for example, information regarding time resource allocation, frequency resource allocation, mini-slot allocation, and or Code Block Group (CBG) transmission. Such information, or similar information, may be used in operations such as mini-slot operations, Code Block Group (CBG) transmission, group common Physical Downlink Control Channel (PDCCH), grant-free and grant-less operations, response to Beam Failure Recovery Request (BFRR), UL Transmit (TX) beam change, Quasi-Co-Location (QCL) operations, aperiodic CSI-RS transmission and interference measurement, Band Width Part (BWP) operations, and Multi-Transmission and Reception Point (TRP)/Multi-Panel.

    Abstract: Multiple mobility sets are maintained for nodes of radio networks. The sets comprise information such as: transmit and receive point identities; cell identities; beam identities; frequency channels; channel bandwidth; and black lists. The sets may be defined at different levels, such as network and physical (PHY) level. A network mobility set, e.g., a new-radio (NR) mobility set may, be determined by the gNB, the cell, the UE, or another device. Multiple radio access network nodes and UEs may exchange mobility set information to achieve a distributed mobility solution. A UE may monitor its orientation relative to a TRP, e.g., via use of an onboard MEMS gyroscope, and alter its beamforming parameters in response to changes in orientation and/or changes in TRP connection strength. Cell selection and reselection for beam based networks may use Single Frequency Network (SFN) broadcast of initial access signals without beam sweeping.

    Abstract: Techniques for improved wake-up signal (WUS) operation in a wireless communication system are described. In accordance with one embodiment, a wireless communications device may receive, from a gNB, information indicating parameters associated with a wake-up signal time window and may power down its first receiver and second receiver based on a discontinuous reception (DRX) cycle. The wireless communications device may wake up the second receiver to receive, from the gNB, a wake-up signal during a configured WUS time window and determine whether a wake-up or a non-wake-up condition is indicated. If a wake-up condition is indicated, then the wireless communications device may wake up the first receiver before an on duration of the DRX cycle to synchronize timing with the gNB, detect a new radio physical downlink control channel (NR-PDCCH) during the on duration of the DRX cycle, and reset a size of the wake-up signal time window.
