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: This application describes methods and apparatus to allocate uplink (UL) power dynamically across multiple parallel radio frequency links for wireless devices. The wireless device sets an initial maximum transmit power level (MTPL) for each UL radio link of multiple radio links used for UL traffic based on a duty cycle prediction for the respective UL radio link. The wireless device adjusts the initial MTPL for each UL radio link based on a predicted data throughput for the UL radio link relative to a total predicted data throughput for all UL radio links. The adjusted MTPL for each UL radio link can be also reduced when the UL radio link uses UL multiple input multiple output (MIMO) transmission via multiple antenna ports, e.g., by apportioning the adjusted MTPL among the multiple antenna ports of the UL radio link equally.

Abstract: Techniques to manage updates for eSIMs of a secondary wireless device are disclosed. Responsive to a user input, expiration of a timer, receipt of a message from an associated primary wireless device, processing circuitry of the secondary wireless device commands an eUICC to update an eSIM. A secure data connection is established between the eUICC and a network provisioning server, either directly from the secondary wireless device to a cellular wireless network or relayed indirectly via the primary wireless device. The eUICC and the network provisioning server exchange messages in accordance with a BIP process to update the eSIM. The eUICC provides a status to the processing circuitry indicating success or failure for the eSIM update. Upon success, a portion of the secondary wireless device may be placed in a reduced power state. Upon failure, the eSIM update process may repeat up to a maximum number of retries.

Abstract: The described embodiments regard detecting a bandwidth part (BWP) mismatch between a wireless device and a cellular wireless network base station and performing mitigation to correct for the BWP mismatch. The wireless device can detect a BWP mismatch, based on content of a downlink control information (DCI) message indicating to switch BWP configurations, which is inconsistent with a scheduled downlink resource or granted uplink resource indicated in the DCI message occurring before completion of a BWP switching delay time period. The wireless device can monitor for DCI messages, after switching BWP configurations, in accordance with a previous BWP configuration for a monitoring time period to confirm use of the new BWP configuration or to detect a BWP mismatch. Responsive to detecting a BWP mismatch, the wireless device switches back to the previous BWP configuration without waiting to complete the BWP switching delay time period for switching BWP configurations.

Abstract: A processor in a mobile wireless device provisions a user identity module (UIM) card in the mobile wireless device in response to a user command. The processor detects a user command to provision the UIM card and reads a provisioning status of the UIM card from a UIM card provisioning status file in the UIM card. When the provisioning status is “not provisioned”, the processor establishes a bearer independent protocol (BIP) data connection to a server in a wireless network and exchanges provisioning data between the server and the UIM card until the UIM card commands the processor to close the BIP data connection. In representative embodiments, the UIM card provisioning status file includes fields for a UIM card provisioning status, a UIM card software version and a UIM card provisioning date/time, and the processor updates the fields during provisioning.

Abstract: This application sets forth techniques for mitigating radio frequency (RF) interference from wired connections on cellular wireless reception quality, including pre-emptively determining when to perform RF interference mitigation based on various factors. An interference mitigation module in the wireless device determines whether to perform an interference mitigation procedure based on active and/or imminent use of a high-speed wired connection port for data transfer in parallel with a cellular wireless connection that uses a mid-frequency RF band or a high-frequency RF band. The wireless device determines a target cell in a low-frequency RF band and biases measurement reports sent to a cellular wireless network to handover and keep the cellular wireless connection to the target cell in the low-frequency RF band while a high-speed wired connection is active.

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.
