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: 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.

Abstract: Techniques for grouping multiple serving component carriers (CCs) are disclosed. In one example, a frequency separation that defines a frequency range from a lower bound frequency to a higher bound frequency for each CC group of a plurality of CC groups may be determined, wherein a difference between the lower bound frequency and the higher bound frequency of each CC group may be equal to the frequency separation. A frequency of a first CC from a collection of CCs may be determined. The first CC may be assigned to a first CC group, of the plurality of CC groups, wherein the first CC group may have a frequency range that includes the frequency of the first CC.

Abstract: Systems and methods provide Layer 1 reference signal received power (L1-RSRP) measurement and transmission configuration indication (TCI) state switching. A cellular communications network determines a plurality transmission reception points (TRPs) configured for high speed train (HST) communication using millimeter wave (mmWave) signals, and generates a synchronization signal block (SSB) index configuration for the plurality TRPs. The SSB index configuration uses non-adjacent SSB indexes between the plurality of TRPs. A user equipment (UE), in response to entering a HST mode, performs L1-RSRP measurement sharing for SSBs received from different TRPs. A scheduling restraint may be used for TCI state switching. Autonomous UL TA adjustment timing may also be used.

Abstract: A user equipment (UE) is configured to communicate with a base station using a set of component carriers (CCs) configured for a carrier aggregation (CA) mode, in accord with a first common transmission configuration indication (TCI) identifier (ID) applied to the set of CCs. The UE is also configured to receive, from the base station, a command to switch from applying a first common TCI ID to the set of CCs to applying a second common TCI ID to the set of CCs; transmit, to the base station, an acknowledgement of the command to apply the second common TCI ID to the set of CCs; and transmit data to or receive data from the base station, using the set of CCs and in accord with the second common TCI ID, after an action delay including a first time period in which the acknowledgement is transmitted. The first time period is based on a smallest subcarrier spacing of the set of CCs.
