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 device, system, and method uses a camp only mode based on a connectivity status. The method is performed at a device that is configured to establish a first connection to a first network and configured to establish a second connection to a second network. The method includes determining the connectivity status of the device. When the connectivity status indicates that the device has established the first connection, the method includes utilizing a camp-only mode to monitor the second network, the camp-only mode reducing a frequency of at least one type of operation associated with the second network, the camp-only mode configured to retain a capability of determining whether an emergency message is being broadcast over the second network.

Abstract: Methods and apparatus for minimizing scheduling collisions between networks. In one embodiment, the networks are substantially unsynchronized, and during hybrid network operation (e.g., LTE and CDMA 1X operation), a mobile device can place CDMA 1X voice calls while registered with the LTE network. However, since the LTE and CDMA 1X networks are not coordinated, the mobile device will experience scheduling collisions. In one variant, the LTE network accounts for predictable behaviors (such as CDMA 1X paging), and schedules low priority tasks during likely time interval conflicts. Consequently, even though the mobile device must tune away from the LTE network to check CDMA 1X pages, overall LTE network performance is minimally affected.

Abstract: A user equipment (UE) determines a transmission power for data transmission to a network. The UE determines a specific absorption rate (SAR) limit associated with the UE and determines a transmission power to be allocated to data transmissions based on one or more applications running on the UE and the SAR limit.

Abstract: Methods and apparatus for dynamic search management in a multi-mode device. In one embodiment, a mobile device performs network search and acquisition by dynamically changing search delays and/or search frequencies. In one implementation, the mobile device adjusts the amount of time allocated for each network search based on e.g., previous network connection history (e.g., previously connected to a home network, previously connected to a roaming network), device conditions, user preferences, geographical information, etc. By focusing search effort on cellular technologies which have a high likelihood of success, the mobile device can greatly improve search time and reduce unnecessary power consumption.

Abstract: Reporting potential impacts of sounding reference signal-switching (SRS-switching) to a base station may include determining that SRS-switching is to be performed by a UE. Based on determining that SRS-switching is to be performed, potential impacts to one or more of a plurality of radio access technologies (RATs) caused by performing SRS-switching while sharing radio frequency (RF) front-ends (RFFE) between at least a subset of the plurality of RATS may be processed. The potential impacts may comprise at least one of transmit-blanking (Tx-blanking) and receive-blanking (Rx-blanking) associated with one or more of the subset of RATs. A communication that indicates the potential impacts of SRS-switching may be encoded for transmission to a base station. The base station may also provide priority configurations for determining how to handle Tx-blanking, Rx-blanking, and SRS-skipping associated with SRS-switching.

Abstract: Apparatus and methods to improve compatibility between a primary wireless device including multiple subscriber identity modules (SIMs) and a cellular capable secondary wireless device are disclosed. The cellular capable secondary wireless device pairs with the primary wireless device, which provides a configurable option to allow mobile terminated connections and/or messages to be received at the cellular capable secondary wireless device for multiple SIMs when the cellular capable secondary wireless device is not within proximity of the primary wireless device and is being worn. The primary wireless device indicates conditional forwarding to a second wireless network associated with a second SIM and adjusts notification alerts to reduce time for forwarding when the cellular capable secondary wireless device is separated from the primary wireless device and in use.

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.
