摘要： Techniques for presenting communication by two or more stations in a WLAN environment are provided. Specifically, methods are presented, that when taken alone or together, provide a device or group of devices with an efficient way for bandwidth adaptation using echo cancellation. Even more specifically, a narrow-bandwidth transmission can be interrupted in favor of a higher-bandwidth transmission upon one or more secondary channels becoming available or going quiet.

摘要： Devices and techniques for out-of-band platform tuning and configuration are described herein. A device can include a telemetry interface to a telemetry collection system and a network interface to network adapter hardware. The device can receive platform telemetry metrics from the telemetry collection system, and network adapter silicon hardware statistics over the network interface, to gather collected statistics. The device can apply a heuristic algorithm using the collected statistics to determine processing core workloads generated by operation of a plurality of software systems communicatively coupled to the device. The device can provide a reconfiguration message to instruct at least one software system to switch operations to a different processing core, responsive to detecting an overload state on at least one processing core, based on the processing core workloads. Other embodiments are also described.

摘要： One exemplary embodiment exploits the non-uniformity of the interference at the downlink STA to maximize the full-duplex MU UL OFDMA transmission throughput performance. A first exemplary technology adjusts the transmit power of the uplink STAs so that the interference caused at the downlink STA is uniform (or substantially uniform) across OFDMA sub-channels. By doing so, the AP can optimize uplink transmission performance (e.g., aggregate link throughput) without degrading downlink transmission performance (e.g., in terms of the MCS used). A second exemplary technology uses OFDMA transmission for downlink, even if there is only one downlink STA, and adjusts the MCS for each downlink sub-channel based on the interference caused by UL STAs on each sub-channel. This allows the DL throughput to be maximized (and higher than a single 20 MHz OFDM transmission).

摘要： Full-duplex communications may incur some inefficiency in spectrum use for many reasons, including traffic asymmetry (e.g., different data sizes for uplink and downlink transmissions), throughput degradation (due to imperfect self-interference cancellation capability), etc. In certain cases, full-duplex communications can be less attractive and efficient, and even underperform the legacy half-duplex communications, for certain communication scenarios. Therefore, full-duplex-capable nodes (e.g., 802.11 AP and STA) should be able to evaluate performance trade-offs between full-duplex and half-duplex operations and be able to dynamically switch between full-duplex and half-duplex modes, instead of statically using full-duplex (or half-duplex) all the time.

摘要： Mobile platform power management is an important problem especially for battery-powered small form factor platforms such as smartphones, tablets, wearable devices, and Internet of Things (IOT) devices. A new low-power wake-up radio (LP-WUR) listens to the wireless medium for a wake-up signal with, for example, below 50 uw power consumption. The LP-WUR allows the mobile platform to completely turn off the main wireless radios, such as Wi-Fi, Bluetooth® (BT), Low-Energy Bluetooth® (BLE), and the like, and then selectively or opportunistically turn them on only when there is data to transmit or receive based on a wake-up signal.

摘要： Mobile platform power management is an important problem especially for battery-powered small form factor platforms such as smartphones, tablets, wearable devices, Internet of Things (IOT) devices, and the like. One exemplary technique disclosed herein defines a method for a fine-grained wake-up mode for Wi-Fi/BT/BLE that utilizes a low-power wake-up radio. For example, the actual data contained in the wake-up packet can be forwarded directly to a memory block of the device without waking-up the Wi-Fi/BT/BLE radio. As another example, if an IEEE 802.11 MAC frame is contained in the wake-up packet, then just the MAC processor of the Wi-Fi/BT/BLE radio can be woken up to process the IEEE 802.11 MAC frame contained in the wake-up packet, and have the PHY module of the Wi-Fi/BT/BLE radio kept powered off or in a low power mode to, for example, save energy.

摘要： The 802.11ax Trigger Frame conveys information for solicited MU UL OFDM(A) transmission information. A full-duplex-capable AP can initiate another DL frame transmission(s) during the UL transmission. However, non-UL-solicited STAs may enter a low-power sleep state right after a Trigger Frame reception, and thus cannot receive the full-duplex DL transmission from the AP. Therefore, to enable OFDMA-based full-duplex communication, the AP needs to explicitly announce both scheduled UL and DL transmission(s) in the Trigger Frame.
