    Abstract: This disclosure describes systems, methods, and devices related to single-radio multi-channel medium access. A device may detect that a primary channel is occupied by a transmission of a first packet by a neighboring station device in an overlapping basic service set (OBSS). The device may detect that a secondary channel is idle. The device may select the secondary channel for packet transmission while the primary channel is occupied by the first packet. The device may cause to send a second packet to a first station device using the secondary channel.

    Abstract: Techniques have been proposed to transmit a wake-up packet at the central 26-tone resource unit of the IEEE 802.11ax OFDMA structure with a low-power wake-up radio packet within the OFDMA allocation. Prior techniques proposed to multiplex transmission of the wake-up packet with IEEE 802.11ax OFDMA PPDUs; leaving the RUs adjacent to the central 26-tone unassigned to function as guard bands. These guard bands are needed to reduce the impact of the adjacent channel interference on the LP-WUR. One embodiment transmits the 26×20 MHz/256=2.03125 MHz wake-up pulse at the center of (or in general anywhere within) the band (e.g., RU5) without requiring the nulling of the seven DC subcarriers. This moves the wakeup pulse inward leaving larger guard bands between the wake-up packet and the adjacent OFDMA allocations. This at least improves the LP-WUR detection performance and will allow assignment of more RUs to IEEE 802.11ax OFDMA PPDUs—Thereby improving overall system throughput and efficiency.

    Abstract: 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.

    Abstract: 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.

    Abstract: 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.
