    Abstract: Various aspects of the disclosure relate to communication using a data unit that includes at least one mid-amble. In some aspects, an apparatus may use mid-ambles for mobility scenarios (e.g., when the apparatus is moving outdoors). The disclosure relates in some aspects to signaling associated with the use of mid-ambles. In some aspects, an apparatus may signal whether it supports sending and/or receiving data with mid-ambles. In some aspects, an apparatus may signal whether a particular data unit includes at least one mid-amble. In some aspects, an apparatus may signal an indication of at least one mid-amble update interval. In some aspects, an apparatus may signal whether a mid-amble includes a short training field.

    Abstract: Techniques are described in this disclosure of a physical layer design for wakeup messages having multiple types of wakeup messages. Such designs may include a standard wakeup message having a first bit duration and a low-sensitivity wakeup message having a second bit duration. During operation, the access point (AP) may select which type of wakeup message to use when communicating with a wireless device or a group of wireless devices. Wakeup intervals during a low-power mode of the wireless device may be adjusted based at least in part on which type of wakeup message is being used. Parameter values for the wakeup messages may be determined based at least in part on proximity of the wireless device relative to the AP.

    Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for an access point (AP) that may identify a pending communication for a wireless device and transmit a wakeup message comprising a device specific identifier to a wakeup radio of the wireless device. The wakeup message may include a preamble, a signal field, and a data field. In some cases, the wireless device may demodulate the wakeup message using a phase modulated on-off keying (PM-OOK) modulation. After awakening, the wireless device and the AP may exchange data using the primary radio, which may be a wireless local area network (WLAN) transceiver or a wireless wide area network (WWAN) transceiver. The wireless device may receive the wakeup message using the wakeup radio, decode the message to obtain a device specific identifier, and activate a primary radio to communicate with the AP.

    Abstract: Methods, systems, and devices for wireless communication are described. A wireless device, such as a device in a wireless local area network, may use a radio frame structure that includes a high efficiency (HE) signal field and an HE data field for communications, for example, over shared radio frequency spectrum. One or more bits or symbols within the HE signal field may be adjusted to avoid a high peak-to-average power ratio (PAPR). In some cases, the adjustment may be to a signal A (SIG-A) or signal B (SIG-B) field. In some examples, a random bit sequence may be used for padding in a signal field. In other examples, bits may be reversed or scrambled. In yet other examples, bits may be modulated and a phase rotation may be applied to the corresponding signal.
