Abstract: Embodiments are presented herein for adjusting the conduct of routine communications of safety messages in V2X networks in order to conserve resources in participating power-limited devices while satisfying V2X system latency demands. Scheduling (e.g., timing and/or frequency) of safety message communications performed by certain UE devices participating in a V2X network may be dynamically adjusted according to various criteria, such as factors relating to the DRX cycle schedule, motion or mobility, traffic environment, and/or battery or power capabilities of the UE devices, which may conserve UE resources and power consumption. Certain UE devices may efficiently transmit safety messages to the V2X network using one of several proposed RACH-based procedures. In some embodiments, the size of safety message communications may be reduced through various compression techniques, and/or by reducing the amount of contained information, e.g., by omitting certain parameters, which may reduce the resources consumed by performing safety message communications.

Abstract: Apparatuses, systems, and methods for high data mode operation in cellular networks. A UE may determine, for an interface to a high-speed cellular network, a categorization from a plurality of categorizations, determine availability of the high-speed cellular network, and select, based at least in part on the categorization and availability of the high-speed cellular network, the interface for a data connection to the high-speed cellular network. The categorization may be one of expensive or not expensive and/or one of a first level associated with a higher compression codec rate or a second level associated with a lower compression codec rate. The UE may receive, from one of the a low-speed cellular network or the high-speed cellular network, carrier plan information for a cellular data service carrier and analyze the carrier plan information to determine desirability of a switch, e.g., from the low-speed cellular network to the high-speed cellular network.

Abstract: Some embodiments enable low power mode for wireless local area network (WLAN) subsystem of an electronic device to improve power usage at the electronic device and increase response time of the WLAN subsystem to prioritized application(s). For example, a method includes enabling a sleep mode of the WLAN subsystem of the electronic device. The electronic device maintains a connection with an access point of a wireless network during the sleep mode. The method further includes receiving a request from an application to communicate with the wireless network. The application is included in a list of prioritized applications. In response to determining that a metric associated with the sleep mode does not exceed a power budget, the sleep mode of the WLAN subsystem is suspended and the communication between the application and the access point of the wireless network is enabled (after the suspension of the sleep mode).

Abstract: An accessory device may establish a short range link to a companion device, and the accessory device may use the companion device as a proxy to conduct a data session over a cellular network. Based on a latency requirement associated with the data session and/or a signal strength of the short range link, the accessory device may dynamically determine to transition its cellular radio from a powered-off mode to a low power mode.

Abstract: A compressor may obtain information indicative of a transmit delay representative of a time duration that elapses between creation (e.g. by the compressor) of a packet and the transmission of the packet, e.g. over a wireless link. The transmit delay may be determined based at least on information indicative of the uplink capacity of the cellular network. The uplink capacity may be determined/obtained based on the uplink throughput and uplink power headroom. When the compressor receives a negative acknowledgement transmission/packet from the decompressor, if the transmit delay is not greater than a specified threshold value, the compressor may process the received negative acknowledgement packet. If the transmit delay is greater than the specified threshold value, the compressor may first discard the buffered compressed packet scheduled to be transmitted next to the decompressor, and transmit an initialization and refresh (IR) or IR dynamic packet to the decompressor instead.

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: Techniques discussed herein can facilitate power management at a User Equipment (UE) via selection of a power management stage based on a current power status. One example aspect is a UE comprising one or more processors configured to: monitor a temperature of the UE via one or more temperature sensors and a power usage of the UE; determine a power status of the UE based at least in part on the temperature of the UE and the power usage of the UE; select, based at least in part on the determined power status, a power management stage of a plurality of power management stages; and implement one or more power management techniques associated with the selected power management stage. A notification can be triggered to alert a user that the processor is implementing the one or more power management techniques prior to implementation.
