Abstract: A user equipment (UE) includes first and second subscriber identity modules (SIMs), possibly subscribed to different carriers. When the first SIM is in a connected state and the second SIM is in an idle state, the UE may need to periodically tune away a radio from a first frequency used for communication under the first SIM to a second frequency used for idle mode activity under the second SIM. The UE may provide to the network of the first SIM the second SIMs traffic activity pattern and/or serving frequency so that the network may provide coordinated configuration and/or scheduling for the UE device, e.g., in order to make the action of tuning away (and tuning back) the radio more efficient and/or to decrease the network impact of such radio tune aways (e.g., to decrease wasted uplink scheduling and wasted downlink transmissions for the first SIM).

Abstract: Apparatuses, systems, and methods for using an assistance information framework to perform fast carrier aggregation and dual connectivity configuration. A wireless device may provide assistance information for determining a carrier aggregation or dual connectivity configuration to a cellular base station. The assistance information may be provided while establishing a radio resource control connection. The assistance information may include either or both of carrier aggregation or dual connectivity preference information for the wireless device or service data amount information for the wireless device. The cellular base station may select a carrier aggregation or dual connectivity configuration for the wireless device based on the assistance information, and may provide configuration information for the selected configuration to the wireless device.

Abstract: Methods and systems are disclosed for a UE of a wireless communication network to recover from MCG radio link failures in a MR-DC system when the SCG is deactivated or otherwise not enabled. When a MCG link failure is detected and the SCG is deactivated, the UE may activate the SCG for the UE to use the SCG link to transmit and receive signaling messages or data as part of the MCG failure recovery procedure. When the MCG link failure is detected and the UE is configured to add the SCG upon the satisfaction of certain condition, but the condition has not occurred, the UE may check to determine whether one condition is MCG failure and whether the radio link quality of the SCG exceeds a threshold. If the radio link quality of the SCG exceeds the threshold, the UE may apply the SCG configuration to add the SCG.

Abstract: Apparatuses, systems, and methods for overhead reduction for multi-carrier beam selection and power control. A user equipment device (UE) may receive an uplink beam configuration for a group of component carriers and may communicate using the uplink beam configuration for the group of component carriers. The UE may receive an updated uplink beam configuration for the group of component carriers. The update uplink beam configuration may include a medium access control (MAC) control element (CE) that may update a pathloss reference signal for the group of component carriers. The MAC CE may include an indication of a spatial relation for aperiodic or semi-persistent sounding reference signals for the group of component carriers, an indication of a transmission control indicator for a physical downlink control channel, an indication of an update for a physical uplink shared channel, and/or an indication of an update for a sounding reference signal.

Abstract: A user equipment (UE) is configured to join a standalone non-public network (SNPN). The receives SNPN information from one or more broadcast messages transmitted from a base station serving as an onboarding base station for the SNPN, determines whether the onboarding base station may be used for onboarding by the UE based on the SNPN information and UE SNPN information stored at the UE and onboards the UE to the SNPN when it is determined that the onboarding base station may be used for onboarding by the UE.

Abstract: Apparatuses, systems, and methods for a user equipment device (UE) to perform a method for supporting a periodical radio access network (RAN) notification area (RNA) mechanism when small data transmission (SDT) is enabled for a user equipment device (UE). The method may include the UE receiving, from a base station, an indication enabling an SDT procedure along with an indication of an RNA timer configuration, transitioning, to a radio resource control (RRC) inactive state, and initiating an RNA timer based on the RNA timer configuration. The UE may, upon initiation of the SDT procedure, stop the RNA timer and, upon termination of the SDT procedure, start the RNA timer. During the SDT procedure, the UE may receive any of an SDT termination indication, an SDT subsequent transmission indication, or an SDT subsequent transmission termination indication that may include an updated RNA timer configuration (and/or RNA timer reconfiguration).

Abstract: Reporting potential impacts of sounding reference signal-switching (SRS-switching) to a base station may include determining that SRS-switching is to be performed by a UE. Based on determining that SRS-switching is to be performed, potential impacts to one or more of a plurality of radio access technologies (RATs) caused by performing SRS-switching while sharing radio frequency (RF) front-ends (RFFE) between at least a subset of the plurality of RATS may be processed. The potential impacts may comprise at least one of transmit-blanking (Tx-blanking) and receive-blanking (Rx-blanking) associated with one or more of the subset of RATs. A communication that indicates the potential impacts of SRS-switching may be encoded for transmission to a base station. The base station may also provide priority configurations for determining how to handle Tx-blanking, Rx-blanking, and SRS-skipping associated with SRS-switching.
