Abstract: A user equipment (UE) indicates to a network the types of SMS messages that the UE does not support. The network receives an indication from the UE corresponding to one or more types of short message service (SMS) messages that are supported by the UE, receives a SMS that is intended to be delivered to the UE, determines whether to forward the SMS message to the UE based on the indication received from the UE, when the SMS message is a type of SMS message supported by the UE, forwards the SMS message to the UE and, when the SMS message is not a type of SMS message supported by the UE, discards the SMS message.

Abstract: A device and method for a user equipment (UE) to implement power savings mechanisms when operating within a significant location. The UE identifies that the UE is at a significant location. The significant location is a location relative to a currently camped cell of a network. At a first time and at the significant location, the UE performs a type of operation related to the network connection. The UE stores information corresponding to the performance of the type of operation at the first time in a profile associated with the significant location. At a second time and at the significant location, the UE performs the type of operation related to the network connection. The performance of the type of operation at the second time is modified based on the information stored in the profile associated with the significant location.

Abstract: The exemplary embodiments describe devices, systems and methods for implementing various exemplary techniques related to fifth generation (5G) new radio (NR) cell search. A user equipment (UE) selects a frequency band to scan during a cell search procedure and identifies a frequency within the frequency band that is associated with a synchronization signal block (SSB) based on an indication of the frequency stored locally at the UE prior to the cell search procedure. The UE then scans the frequency for the SSB and determines that the SSB has been broadcast by a cell over the frequency.

Abstract: A device, system, and method persists network registration rejection causes. The method is performed at a device connected to a network and comprising a temporary memory and a persistent memory, the device using the data stored in the temporary memory when performing network registration operations. When a power cycle is detected, the method includes determining whether there is persistent data in the persistent memory for a first attempt to register with the network prior to the power cycle, the persistent data including a rejection cause for the first attempt. When there is the persistent data in the persistent memory, the method includes determining whether the persistent data is valid for a second attempt to register with the network after the power cycle. When the persistent data is valid, the method includes generating and storing cause data based on the persistent data in the temporary memory prior to the second attempt.

Abstract: A user equipment (UE) may be configured to reattempt to establish a multiple access (MA) protocol data unit (PDU) session when the UE moves to a new registration area. The UE transmits a request for a MA PDU session to the network, receives a message from the network indicating the request has been rejected, wherein the message further includes a status indication for reattempt requests to establish the MA PDU session, determines, when the UE moves into a new registration area of a PLMN, whether reattempt requests are allowed based on, at least, the status indication and transmits, when reattempt requests are allowed, a further request to establish the MA PDU session.

Abstract: Embodiments described herein relate to managing access to 5G cellular baseband resources for 5G-capable wireless devices. A wireless device can monitor application workloads by analyzing communication network performance requirements for a given application in-use or launching for future use along with system-level indications of overall device usage, battery level, and mobility status to determine whether access to 5G cellular baseband resources is recommended for an application. A 5G cellular baseband resource recommendation is provided for an application indicating a level of bandwidth in current use or expected for future use as well as a confidence metric in the bandwidth level indication. The 5G cellular baseband resource recommendation is used with additional device criteria to determine whether access to one or more 5G radio frequency bands is allowed.

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.
