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: Embodiments described herein relate to dynamic selection of radio access technologies (RATs) available for use by 5G wireless devices. Managing selection of RATs to use by a 5G (and 4G LTE) capable wireless device can improve performance, e.g., when an application requires a higher throughput and a 5G SA connection underperforms a 5G NSA connection or a 4G LTE connection. Wireless devices can provide geolocation tagged cellular wireless network information, e.g., network performance measurements and observed properties, to network-based servers that collate and organize the crowd-sourced cellular wireless network information into a location database. The wireless device can use the cellular wireless network information of the location database for a geolocation at which the wireless device is operating to estimate performance for alternate wireless connections and compare to measured performance of a currently used wireless connection to determine whether to switch wireless RAT connections.

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 user equipment (UE) is associated with a cellular network, the UE and the cellular network are configured with a Discontinuous Reception (DRX) functionality, the DRX functionality including a cycle with a plurality of onDurations. The UE receives an indication of at least one parameter the cellular network is to utilize for the transmission of an emergency message, generates a monitoring schedule based on the indication of the at least one parameter, wherein the monitoring schedule does not include at least one of the plurality of onDurations and activates a mode of operation where the UE monitors for the emergency message based on the monitoring schedule.

Abstract: A method is disclosed where a user equipment (“UE”) determines that the UE is in a connected mode. The UE then determines a connection type of the connected mode and prioritizes a measurement report based on the connection type. The method may also be performed by an integrated circuit of the UE.
