Abstract: Disclosed are techniques for differentiating between licensed and unlicensed bands in a common portion of frequency spectrum to facilitate initial access in a fifth generation (5G) new radio (NR) wireless communication system having an NR node. The techniques include an NR generating and UE processing frequency configuration information indicating whether the common portion of frequency spectrum is allocated as a licensed band or an unlicensed band to enable a determination that the frequency spectrum is configured as the licensed band or unlicensed band and thereby facilitate initial access.

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: Techniques for channel state information reference signal (CSI-RS) configuration in wireless communications are disclosed. A user equipment (UE) may decode a message including a CSI-RS configuration that indicates a CSI-RS window associated with one or more CSI-RS, with respect to one or more mobility related measurements. The UE may determine one or more mobility related measurements using the CSI-RS configuration, and measure the one or more CSI-RS using the determination of the one or more mobility related measurements. The UE may generate a report for the base station corresponding to the measurement of the one or more CSI-RS.

Abstract: Apparatuses, systems, and methods for beam indication latency reduction via symbol level beam sweeping capability reporting. A wireless device may transmit, to a base station, a report associated with symbol level beam sweeping. The wire wireless device may receive, from the base station, a symbol level beam sweeping configuration. The symbol level beam sweeping configuration may be based, at least in part, on the report. The wireless device may perform synchronization signal block (SSB) measurements according to the report and the symbol level beam sweeping configuration.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE) to perform PUCCH repetition based on signaling from at least one base station. The UE may connect to at least one base station. The UE may receive signaling from the at least one base station configuring physical uplink control channel (PUCCH) transmission. The signaling may indicate a plurality of PUCCH resources for PUCCH repetition. The signaling may indicate a plurality of beams for PUCCH repetition. Based on the signaling from the at least one base station, the UE may transmit the PUCCH a plurality of times using the plurality of PUCCH resources and the plurality of beams.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE) to perform beam failure detection. The UE may establish communication with a base station. The UE may determine one or more beams to perform downlink communication from the base station. The UE may receive, from the base station, an indication of a first type of downlink reference signals to perform beam failure detection. The UE may perform signal quality measurements for the one or more beams using the first type of downlink reference signals. The UE may determine beam failure of at least one beam of the one or more beams based on said performing signal quality measurements.

Abstract: The present application relates to devices and components including apparatus, systems, and methods to provide SCell activation. In one example, an SCell activation procedure may be extended by a duration based on cancelation of CSI-RS reception. In another example, a base station may use particular configuration parameters to avoid cancelation of CSI-RS reception. In yet another example, a UE and a base station may use particular information for a CSI-RS reception/transmission on an SCell that is being activated.

Abstract: The present application relates to wireless devices, and more particularly to apparatus, systems, and methods for radio link monitoring beam management in 5G-New Radio (NR) for Ultra-Reliable Low-Latency Communication (URLLC). In one embodiment, a method for signal quality monitoring in a wireless system is disclosed, comprising: determining, by a user device, to connect to the wireless system in a high reliability mode, and determining, based on the determination to connect to the wireless system in the high reliability mode, to use, by the user device, a first pair of out-of-sync (OOS) and in-sync (IS) block error rate (BLER) threshold values and/or a first set of transmission parameters for radio link monitoring (RLM), rather than a second pair of OOS and IS BLER threshold values or a second set of transmission parameters that are configured for use in a non-high reliability mode.
