Abstract: A network component communicating with a user equipment (UE) and a server. The network component receives a first packet from the UE, wherein the first packet indicates to the network component that the network component is to perform operations on behalf of the UE to maintain a persistent connection, receives a second packet from the server and determines whether to transmit a signal to the UE based on the second packet received from the server. A UE having a transceiver and a processor. The UE transmits a first packet to the network component, wherein the first packet indicates to the network component that the network component is to perform operations on behalf of the UE to maintain a persistent connection, identifies an out of service (OOS) event, receives registration information from the network component and registers with the server based on the registration information received from the network component.

Abstract: Systems, methods, and apparatuses disclosed herein can compensate for imbalances between multiple transport streams of an uplink (UL)-multiple-input and multiple-output (MIMO) transmission. These systems, methods, and apparatuses can adjust one or more signal metrics of multiple recovered transport streams of the UL-MIMO transmission that are received in the presence of imbalances between the multiple transport streams of the UL-MIMO transmission. As an example, these systems, methods, and apparatuses can inject noise into one or more of the multiple recovered transport streams to adjust the one or more signal metrics of the multiple recovered transmission streams to lessen the imbalances between the multiple transmission streams. As another example, these systems, methods, and apparatuses can attenuate and/or amplify transmit powers of one or more the multiple transport streams for the UL-MIMO transmission to adjust the one or more signal metrics of the multiple recovered transmission streams to lessen the imbalances between the multiple transmission streams

Abstract: Apparatus and methods to support parallel access to services of multiple subscriber identity modules (SIMs) and/or electronic SIMs (eSIMs) by a wireless device are disclosed. The wireless device is a single-radio wireless device that includes wireless circuitry that supports an active voice or video connection via a single radio access network of a cellular wireless network at a time. To send or receive data for a second SIM/eSIM, when an active voice or video connection for a first SIM/eSIM uses the wireless circuitry, the single-radio wireless device can i) establish parallel, linked protocol data unit (PDU) sessions for different SIMs, ii) multiplex traffic for different SIMs over a common radio connection with SIM information embedded in protocol headers for routing by network equipment, and/or iii) use an additional dedicated bearer using a first, active SIM for each data network name (DNN) over which to route for a second, suspended SIM.

Abstract: Systems and methods provide secondary cell group (SCG) activation and deactivation. A user equipment (UE) in a wireless network may determine bandwidth part (BWP) configurations for a carrier of a primary secondary cell (PSCell) of an SCG for dual connectivity (DC). The UE may move between an SCG activation state and an SCG deactivation state based on the BWP configurations. SCG deactivation modeling may be based on a separate BWP configuration or may be modeled via a separate configuration in radio resource control (RRC) that is applicable to the BWPs in a serving cell.
