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: Techniques are described for using a dedicated-scan radio to improve scanning and other radio operations performed during wireless communications. The techniques include configuring a dedicated-scan radio to collect and cache scan results without interfering with ongoing wireless communication tasks performed using primary radios. Based on the scan results cached by the dedicated-scan radio, the computing device improves other radio operations in furtherance of wireless communications. Cached scan results enable a primary radio to avoid, or to focus on, scanning certain channels or frequencies during discovering, positioning, or roaming operations. By using the dedicated-scan results as a starting point or seed for functions performed by a primary radio, the computing device may more quickly and more efficiently perform radio functions, minimizing latency to ongoing wireless communications.

Abstract: Methods and apparatus allow a mobile device to proactively switch to a new network by using quality of connection information and the rate of change of the received signal strength indication (RSSI) to proactively switch from a first network, such as a WiFi network, to the new network, such as another WiFi network or a cellular network. For example, the mobile device determines a rate of change of the RSSI for the first network. Based on the rate of change of the RSSI, the mobile device predicts when the RSSI of the network is beyond a quality threshold. Based on the prediction, the mobile device switches from the first network to a second network. In another example, the method and device uses a quality of connection of the first network connection to determine when to switch from a first network connection to a second network connection.

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: This document describes improvements in management of data traffic of user equipment between cellular and non-cellular accesses in fifth generation new radio, 5G NR, wireless networks. An energy-aware traffic manager is introduced to manage data traffic communicated by the user equipment over the cellular access and the non-cellular access, such as a wireless local area network, WLAN. The energy-aware traffic manager enables reporting of energy-related information by user equipment, energy-aware traffic management modes for the user equipment, and access management in response to critical events related to user equipment energy, as well as reporting of changes in the user equipment access management or access management modality to core network entities. By so doing, the energy-aware traffic manager enables data traffic management based on aspects of user equipment energy, which may reduce user equipment energy consumption associated with communicating data over multiple accesses and extend battery life of the user equipment.
