摘要： 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.

摘要： 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.

摘要： A device providing inter-device call continuity facilitated by a wireless audio output device may include a processor configured to initiate, over a peer-to-peer connection with a second device, a communication session between the second device and a third device. The processor may be further configured to establish, over the peer-to-peer connection with the second device, an audio link corresponding to the communication session. The processor may be further configured to determine, based at least in part on the audio link, that a connection quality of the peer-to-peer connection satisfies a connection degradation condition. The processor may be further configured to request, over a wide area network connection, for the communication session with the third device to be handed-off from the second device to the first device, and to establish, over the wide area network connection, the communication session with the third device.

摘要： Embodiments are presented herein of apparatuses, systems, and methods for a user equipment (UE) device to adaptively enhance the quality of service (QoS) configuration of a bearer of communications conducted over a cellular network between a UE application and a server. The UE may use various information, including a QoS profile associated with the application, to determine requested QoS parameters and/or whether the UE is permitted to request or access enhanced QoS functionality. The UE may then send a request to the cellular network indicating the requested QoS parameters, and the network may adjust the QoS configuration of the bearer in response. The UE and the network may perform routine QoS measurements and exchange information in order to adaptively maintain and optimize the QoS configuration. These techniques may tend to provide more appropriate QoS to the application, which may improve user experience.

摘要： Apparatuses, systems, and methods for a wireless device to perform methods to implement mechanisms for performing autonomous and non-autonomous side-link resource management as well as groupcast side-link resource management. A wireless device may perform a method for autonomous (e.g., non-network assisted) side-link resource management, e.g., the wireless device may perform a method to originate a semi-persistent side-link schedule for a side-link resource (e.g., a time domain and/or a frequency domain resource for side-link communications). Additionally, a wireless device may perform a method for groupcast side-link resource management. A network node may perform a method for non-autonomous (e.g., network assisted) side-link resource management, e.g., the network node may perform a method to assist wireless devices to schedule side-link resources.

摘要： 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.

摘要： Systems, methods, and mechanisms for performing ROHC header compression on TCP packets with MPTCP option enabled. A compressor may determine that a first portion of the stream of data packets is formatted according to the transmission control protocol (TCP) with a multipath TCP (MPTCP) option enabled. The compressor may establish context with a corresponding decompressor and may operate in one of three modes of compression based on the context. In some embodiments, when the context indicates that the corresponding decompressor supports decompression of TCP data packets with MPTCP option enabled, the compressor may operate in a first or second mode of compression. In some embodiments, when the context indicates that the corresponding decompressor does not support decompression of TCP data packets with MPTCP option enabled, the compressor may operation in a third mode of compression.
