Apparatuses, systems, and methods for application aware cellular radio activation/deactivation, e.g., in 5G NR systems and beyond. The UE may receive, while operating in a power savings mode in which a cellular modem of the UE is disabled, inputs associated with an application of the UE. The UE may determine, based on the inputs, to activate the cellular modem to support the application of the UE. The inputs may include an indication of an application state or status, an indication of an application category, an indication of a state or status of an AI assistant of the UE, an indication of whether an application is a session application, an indication of network assertions, an indication of proximity information, an indication of a WiFi state or a WiFi status, and/or indications associated with one or more timers.

Methods and procedures for extended battery life

A device executing a low-latency application that uses a Wi-Fi link may switch from the Wi-Fi link to using a second link to a multi-subscriber (MSIM) PHS device. The device may access, via the second link, any one of multiple cellular links, each cellular link corresponding to a different respective cellular subscription of multiple subscriptions used by the PHS device. The application executing on the device may thus use a preferred cellular link from among the multiple cellular links. The preferred cellular link may be determined based on parameters corresponding to the plurality of cellular links for each respective cellular subscription. The parameters may be obtained from a location database. The preferred cellular link (which may presently correspond to a primary subscription) on the PHS device may be switched to be a different cellular link (which may correspond to a non-primary subscription) during execution of the application on the device.

Radio access technology management for wireless communications of multi-subscriber-identification-module (MSIM) low latency hotspot devices

This disclosure relates to techniques for a wireless device to autonomously perform certain cell measurements in a wireless communication system. A wireless device may establish a wireless link with a cellular base station. The wireless link may be established according to a first radio access technology. The wireless device may determine whether at least one cell that operates according to a second radio access technology is available at the current location of the wireless device based on information stored by the wireless device. If at least one cell that operates according to the second radio access technology is available, the wireless device may perform one or more cell measurements on a cell that operates according to the second radio access technology.

Autonomous cell measurements

Techniques described herein may enable a user equipment (UE) to optimize radio access technology (RAT) and radio resources (e.g., bandwidth parts (BWPs)) when communicating with the network. This may be based on one or more factors or conditions, such as whether the UE is currently using 4th generation (4G) RAT or 5th generation (5G) RAT, whether the UE is in an active mode or idle mode, a BWP used by the UE, whether an application or network service requires a certain throughput, a type of application being used by the UE, an amount of network congestion, and so on. RAT optimization may also be based on whether the UE is using a frequency range 1 (FR1) or frequency range 2 (FR2), whether the UE is stationary or moving, whether the UE is experiencing beam failures, uplink (UL) switches, link quality measurements (LQMs), reference signal received power (RSRP) measurements, and so on.

Systems, methods, and devices for optimizing radio access technology and resource selection

A user equipment (UE) configured to establish a multimedia data stream with a further UE, identify a predetermined condition, wherein the predetermined condition indicates a decrease in quality of the multimedia data stream at the further UE and implement a mechanism to mitigate the degradation of the decrease in quality of the multimedia data stream at the further UE.

Mitigating the degradation of quality of a multimedia data stream at a remote endpoint

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.

Smart data mode for 5G wireless devices

A connected car and an onboard user equipment (UE) may establish independent cellular connections and may also establish a connection between each other. The UE establishes a first cellular link between the UE and a first network, establishes a connection with a connected car, wherein the connected car has a second cellular link between the connected car and a second network, evaluates one or more conditions and declares one of the first cellular link or the connection with the connected car a primary network interface for the UE based on, at least, the one or more conditions.

Enhanced network connectivity for a connected car and onboard user equipment

Wireless devices, networks and methods may operate to have a wireless device cause a base station to trigger voice call continuity handovers responsive to the quality of the cellular radio link in addition to the base station triggering such handovers based on location or mobility. Furthermore, wireless communication devices may also perform monitoring of multiple buffers operating within the wireless communication device and associated with different respective communication layers, in addition to monitoring the quality of the cellular radio link, to perform intelligent dropping/discarding and/or scheduling of packets at the wireless communications device. Any one or more of these features may improve the ability of the wireless communications device to achieve stated Voice over Long Term Evolution (VoLTE) performance benchmarks in the context of the realities of current VoLTE networks.

Link quality based single radio-voice call continuity and packet scheduling for voice over long term evolution communications

Techniques are disclosed relating to a mobile device that initiates handovers from short-range networks to long-range networks. In various embodiments, a mobile device includes one or more radios that communicate using a plurality of radio access technologies (RATs) including a cellular RAT and a short-range RAT. In such an embodiment, the mobile device stores an indication that the cellular RAT is a preferred RAT for a communication session. The mobile may establish the communication session using the preferred RAT, and in response to determining that a quality of the preferred RAT fails to satisfy a set of quality criteria, may request that the communication session use the short-range RAT. In some embodiments, the mobile device analyzes average packet error rate for the communication session and in response to the average packet error rate satisfying a threshold, requests that the communication session use the cellular RAT.

Performing handover between short-range and cellular wireless networks

This disclosure relates to transport link selection for an accessory wireless device in association with a companion device. The accessory device may communicate via a short range wireless communication link with the companion device. The companion device may detect an event and, based on the event, transmit assistance information to the accessory device. The accessory device may evaluate various conditions. The accessory device may select a transport link and/or short range link based at least in part on the received assistance information and/or the evaluated conditions.

Companion assistance and efficient link selection for wearable devices

A self-organizing device may include a recovery control module which may monitor different events from various different domains, for example from different layers of the software stack, associated with wireless communications of the device. Upon identifying a specific condition based on the monitored information, the device may execute a corresponding auto-recovery mechanism to mitigate adverse effects of the condition experienced by the device. Devices may provide monitored information to servers, e.g. to cloud servers, which may use expert systems to analyze the information collected from multiple devices, for example from globally dispersed devices, and may define mitigation action responses corresponding to specific scenarios or conditions that include device-specific considerations. The mitigating action responses may be deployed to the devices by the servers as expert system rules in the form of uncompiled code or hot patch code that the devices may later use to implement the necessary mitigation actions as warranted.

Self-organizing device

A system and method for operation of a user equipment (UE) to determine a cellular network bottleneck in a downlink channel, and an apparatus for use in a UE for determining the same. A UE may determine a burst of network traffic from network traffic received from the cellular network during a series of transmission time intervals. The UE may analyze resource allocations to the UE during the burst to determine an extent to which the cellular network is busy. The UE may determine that the cellular network is experiencing a bottleneck based at least in part on the analysis of the resource allocations to the UE in the burst.
