    Abstract: Provided is a method performed by a user equipment (UE), comprising: receiving, from a network (NW) comprising a master node (MN) and a secondary node (SN), one or more messages comprising pre-configured measurement gap (pre-MG) configurations for at least one pre-MG, wherein the UE is in dual connectivity (DC) with the MN and the SN; and determining, from the pre-MG configurations, respective pre-MG statuses for the at least one pre-MG, wherein the MN comprises a master cell group (MCG) and the SN comprises a secondary cell group (SCG).

    Abstract: Apparatuses, systems, and methods for mitigation of listen before talk conflicts in the unlicensed spectrum. A wireless device may receive one or more synchronization signal blocks (SSBs) from a base station (BS) as part of a measurement procedure with listen before talk (LBT). The wireless device may determine one or more LBT failures associated with one or more receive beams of the wireless device. Furthermore, in response to determining the one or more LBT failures associated with the one or more receive beams of the wireless device, the wireless device may extend a measurement period for the one or more receive beams of the wireless device. The wireless device may then receive one or more additional SSBs on the one or more receive beams of the wireless device.

    Abstract: Methods, systems, and storage media described herein may have the complexity to support simultaneous communications (e.g., transmission/reception to/from) with two or more cells. Therefore, before configuring a handover, the network needs to know if these methods, systems, and storage media can support simultaneous communication with multiple cells or not. Among other things, these methods, systems, and storage media can reduce the interruption time during handovers for when these methods, systems, and storage media are capable of such simultaneous communication.

    Abstract: Systems and methods for networks having user equipment (UE) that can perform measurement/reporting of received signals and a sounding reference signal (SRS) transmission that is part of an SRS antenna port switching procedure are described herein. In some circumstances, the measurement and the SRS antenna port switching procedure overlap on one or more symbols. Across various embodiments, the UE prioritizes one of the measurement and the SRS antenna port switching procedure based on one or more of a scheduling type (periodic, semi-persistent, aperiodic) of the measurement, a scheduling type of a channel state information (CSI) report for a measurement result for the measurement, and/or a scheduling type of the SRS transmission of the SRS antenna port switching procedure. Networks that avoid overlaps by scheduling SRS transmissions away from UE signal measurements, or transmissions of signals to be measured away from UE SRS antenna port switching procedures, are also described.

    Abstract: Provided is a method for a user equipment (UE). The UE obtains a physical uplink control channel (PUCCH) secondary cell (SCell) activation command from a primary cell (PCell) or primary secondary-cell-group cell (PSCell). The PUCCH SCell activation command is used for an PUCCH SCell activation of a target PUCCH SCell for the UE. The UE performs PUCCH SCell activation operations associated with a valid timing advance (TA) and the PUCCH SCell activation command. TA is considered to be a valid TA when the TA meets a preset criterion. The UE generates a channel state information (CSI) report for transmission to at least one of the PCell, PSCell and the target PUCCH SCell. The CSI report indicates that the PUCCH SCell activation is completed.

    IPC: H04L5/00

    Abstract: Techniques discussed herein may better ensure efficient fine time tracking during a second cell (SCell) activation procedure by using a tracking reference signal (TRS) that is User Equipment (UE) specific. A primary cell (PCell) may provide a UE with a TRS configuration that includes a UE-specific reference signal (RS) with aperiodicity. In response to receiving a SCell activation command from the PCell, the UE may perform cell activation in accordance with the UE-specific RS. As the delay time for the UE-specific RS may be less than the delay time for a system synchronization block (SSB) from the SCell, use of the UE-specific RS may expedite the cell activation procedure.
