Abstract: A user equipment (UE) employing different radio access technologies (RATs) concurrently or successively provides the UE the opportunity to select a particular RAT to support an access service used by one or more software applications of the UE. A RAT operational control scheme provides for opportunistic enablement and disablement of a RAT and/or intra-RAT configuration so as to provide sufficient uplink and downlink throughput for supported software applications while reducing unnecessary power consumption by the UE, which often is battery powered.

Abstract: This document describes methods, devices, systems, and means for a switching scheme for opting in and out of multi-user orthogonal frequency-division multiple access (MU-OFDMA). In one aspect, an electronic device enters the MU-OFDMA mode to communicate via a wireless network over a shared-channel bandwidth. During the MU-OFDMA mode, the electronic device determines that an uplink-queue size is greater than a first threshold size. Responsive to the determining, the electronic device opts out of the MU-OFDMA mode and enters a single-user mode to contend for a transmit channel for transmitting uplink data.

Abstract: This document describes methods, devices, systems, and means for the provisioning of enrollee Wi-Fi devices to a Wi-Fi network. Many Wi-Fi devices have limited or no user interface capabilities, which presents challenges to connecting and, especially, securely connecting many of these devices to a Wi-Fi network. Techniques are described to enhance the Device Provisioning Protocol to solicit and provide feedback from an enrollee device to indicate band support of the enrollee device and provide the status of the enrollee device after attempting to join a provisioned Wi-Fi network.

Abstract: A user equipment (UE) is configured to request connection to a selected one of a plurality of available network slices of a network system. The UE implements a permission control framework that allows individual applications to request connection to the selected network slice, but establishes the connection only when the framework determines, based on any of a variety of permission criteria, that the application is permitted to access the requested network slice. The UE also supports user selection of the network slice via a graphical user interface that presents a selectable list of available network slices.

Abstract: Methods, systems, and apparatus, including computer-readable media, for enabling a client device to learn characteristics of one or more access points in a wireless network used by the client device. In addition to learning the characteristics of the access point, the client device also can learn its own hardware characteristics, its usage profile, its environmental operation condition, its user preferences, and its computing context. The client devices uses the learned characteristics to realize computing efficiencies based on dynamic configuration of wireless network settings at the client device.

Abstract: An ultra-wideband (UWB) ranging method comprises determining, by a first device, that the first device is within proximity of a second device. Responsive to the determination, the first device negotiates a value to use as a UWB session key for securing UWB communications with the second device. The negotiation occurs via a communication protocol different from a UWB communication protocol. The first device controls a UWB subsystem therein to encrypt information communicated via the UWB subsystem based on the negotiated value of the UWB session key instead of a default value for the UWB session key that is specified in the UWB communication protocol. The information facilitates determining the distance between the first device and the second device.
