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: An electronic device may be provided with first and second sidewalls, a rear wall, and a display. Multiple antenna panels may be used to convey radio-frequency signals at frequencies greater than 10 GHz. A first antenna panel may radiate through the display while second and third panels radiate through the first and second sidewalls. The second and third panels may be tilted at non-zero angles with respect to the sidewalls. The non-zero angles may be of opposite sign. The non-zero angles may have the same magnitude. The magnitude may be equal to 15 degrees, as one example. Tilting the panels in this way may allow the panels to collectively cover as much of a sphere around the device as possible, including out of coverage areas behind the rear wall caused by conductive material in the rear wall, without requiring additional panels to be disposed within the device.

Abstract: This application describes systems and processes for beam selection performance refinement in static conditions of wireless devices (e.g., user equipment UE). A data processing system of the UE is configured to perform a beam scan for testing multiple high gain candidate beams on a physical downlink shared channel (PDSCH) and link adaptation (LA) channel state information reference signal (LA-CSI-RS) while the UE is not moving and the data processing system of the UE determines that the channel is stable. The data processing system is configured to refine a given beam choice based on a determined capacity of the beams (e.g., from PDSCH signaling and/or LA-CSI-RS signals) to optimize data throughput.

Abstract: Methods and apparatus to manage registration for cellular services of a secondary wireless device associated with a primary wireless device are disclosed. The secondary wireless device can detect entering proximity to the primary wireless device and in response to the detecting deactivate a cellular wireless interface of the secondary wireless device to conserve battery power, and provide an indication to the primary wireless device, via a non-cellular wireless interface, to cause the primary wireless device to perform a deregistration of the secondary wireless device for cellular services. The secondary wireless device can establish connections and communicate via non-cellular wireless interfaces while within proximity of the primary wireless device. Upon leaving proximity of the primary wireless device, the secondary wireless device can activate the cellular wireless interface and register for cellular services to permit establishing connections and communicating directly with a cellular wireless network via the cellular wireless interface.

Abstract: Some embodiments relate to a cellular network which better utilizes packet-switched (PS) voice technologies, such as VoLTE, for roaming user equipment (UE) devices. When a roaming UE associated with a home cellular carrier that does not support PS to CS handover (SRVCC) desires to make a VoLTE call, the cellular network may determine probability of such a handover during the the call. The cellular network may selectively accept or reject the packet-switched wireless voice call based on the handover probability. If the probability of handover is high, the cellular network may reject the packet-switched wireless voice and trigger the UE to fall back to a circuit-switched network and re-originate the wireless voice call on the circuit-switched network. In the case of a mobile terminated call, the cellular network may provide signaling to the UE to perform a fallback to a circuit-switched network in order to receive the mobile terminated call.

Abstract: A method includes a wireless mobile device communicating with a wireless network via an evolved high rate packet data (eHRPD) interface. The wireless mobile device may receive a vendor specific network control protocol (VSNCP) packet such as a terminate-request packet, for example, that indicates the wireless network has requested a PDN disconnection. The VSNCP packet includes a cause code that indicates a reason for the PDN disconnection request. The wireless device may use the cause code to determine the reason for the PDN disconnection request. Accordingly, in response to receiving the VSNCP packet, the wireless mobile device may perform one or more operations in an effort to resolve any issues that may have caused the PDN disconnection request.

Abstract: A user equipment (UE) device may communicate according to a new device category satisfying specified QoS (quality of service) requirements while also satisfying specified link budget requirements, and additional optimization requirements. The new device category may identify the UE device as a wearable device. According to some embodiments, LTE category M may be extended to support non-MTC operations performed by wearable devices. For example, the new device category may support UE mobility and may disallow access barring. Additional extensions may be implemented in response to an indication by the UE that the UE is implementing a specific application, such as VoLTE or a near real-time application, such as audio streaming. In some scenarios, the indication may include the UE indicating a specific QCI value. In some scenarios, the indication may include the UE attaching to a specific APN.

Abstract: In some embodiments, a cellular baseband processor communicates wirelessly and reports cellular metrics for both a first cellular RAT and a second cellular RAT. The cellular baseband processor may be configured to tune away, for a time interval, from the first cellular RAT to monitor for communications on the second cellular RAT. In some embodiments, the cellular baseband processor is configured not to report cellular metrics during the time interval to prevent a RAT manager from setting up a connection for voice calls on a WLAN RAT during the time interval. In some embodiments another processing element the RAT manager is configured to ignore cellular metrics from the cellular baseband processor during the interval. This may reduce signal load and power consumption, in some embodiments.
