    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.

    Abstract: The present disclosure relates to apparatus, methods, computer-readable storage medium and computer program product for high speed train measurements and signaling. A wireless device, comprising: at least one antenna; at least one radio coupled to the at least one antenna; and a processor coupled to the at least one radio; wherein the processor is configured to: receive, via the at least one radio, at least one Radio Resource Control (RRC) signaling from a cellular base station, the at least one RRC signaling at least comprises one or more information element (IE) of a group of IEs, wherein, the group of IEs at least includes a first IE indicating to enable or disable enhancement on a Secondary Cell (SCell) in Frequency Range 2 (FR2), and a second IE indicating to enable or disable enhancement on a Primary Secondary Cell (PSCell); and perform enhancement on one or more corresponding cells in response to the received at least one RRC signaling, wherein, the enhancement comprises determining a reduced time period for Primary Synchronization Signal (PSS)/Secondary Synchronization Signal (SSS) detection and/or determining a reduced time period for intra-frequency measurements.

    Abstract: Techniques described herein include solutions for utilizing dual port synchronization signal block (SSB) transmissions for multiple receive (Rx) beam selection. In some aspects, a base station transmits a first SSB with a first polarization on a first antenna port, and transmits a second SSB with a second polarization on a second antenna port. The first and second SSBs may be transmitted, for example, using a first transmission reception point (TRP). A user equipment (UE) receives the first and second SSBs, and identifies one or more optimal Rx beams for multiple-input multiple-output (MIMO) communication based on the first and second SSBs.
