  • Publication number: 20180255514
    Abstract: Techniques and apparatus for wake-up radio (WUR) operations are provided. One technique includes communicating with one or more wireless devices via a first radio operating on a first channel. A WUR is operated on a second channel different from the first channel. A wireless device may receive an indication of the second channel to use for monitoring for WUR transmission, and monitor for a WUR transmission on the second channel after receiving the indication.

  • Publication number: 20180249412
    Abstract: Methods, systems, and apparatuses for wireless communications are described. Stations operating within a system may have a primary radio and a wakeup or low-power radio. Access points (APs) may send indications receivable by the wakeup radio to alert a station of a pending data transmission for the station. APs may transmit synchronization beacons for wakeup radios of the stations, and the transmission timing for the synchronization beacons may be adapted based on operating conditions of one or more stations. For example, an AP may skip transmissions of a synchronization beacon or may adapt the frequency of synchronization beacon transmissions based on various operating conditions or factors. Stations may report certain information about operating conditions or capabilities that may be used to adapt synchronization beacon transmissions.

  • Publication number: 20180249413
    Abstract: A method and an apparatus for wireless communication are provided. In one configuration, an apparatus is configured to transmit a wake-up radio (WUR) signal, to determine to transmit a second signal within a SIFS after transmitting the WUR signal to increase medium reuse, and to transmit the second signal within the SIFS after transmitting the WUR signal based on the determination. The second signal may be a data, management, control, ACK, or CF-end frame to enable legacy devices that do not decode the WUR signal to avoid wasted airtime cause by EIFS after the WUR signal. In another configuration, the apparatus is configured to transmit a CTS-to-self frame, to determine to transmit a second signal within a SIFS after transmitting the CTS-to-self frame, and to transmit the second signal based on the determination. The second signal may be a WUR signal or an intermediate signal followed by a WUR signal.

  • Publication number: 20180234918
    Abstract: Methods, systems, and devices for wireless communication are described. An access point (AP) may establish a wakeup radio listen schedule for a station (STA) such that a wakeup radio of the STA is powered on to listen for wakeup messages according to wakeup signals transmitted by the AP (e.g., to power on a primary radio). The AP may identify synchronization information such as clock, interval, and offset information for the wakeup radio listen schedule, and may transmit the synchronization information to the STA, such that the STA may synchronize the wakeup radio for wakeup messages. In some cases, the STA may monitor for the synchronization information using a primary radio (e.g., from periodic beacon signals sent by the AP). In other cases, the STA may receive synchronization information in a wakeup signal (e.g., using the wakeup radio). In some examples, the STA may indicate a preferred synchronization mechanism in advance.

  • Patent number: 10015810
    Abstract: A method for communicating in a wireless sensor network (WSN) is described. Using control logic, a first wireless transceiver is caused to transmit a wireless packet to a node in a wireless sensor network. The control logic bases its causing on a transmission coinciding with a break in transmission for a second wireless network, such that the transmission from the first wireless transceiver does not coincide with transmissions made on the second wireless network. Time synchronized channel hopping (TSCH) slot frames for wireless packet transmission in the wireless sensor network are caused to be time offset if the first wireless transceiver is utilizing TSCH. Wake up sequence transmissions for the wireless sensor network are caused to be time offset if the first wireless transceiver is utilizing coordinated sampled listening (CSL).

  • Patent number: 9629071
    Abstract: A first AP in a wireless network determines that a wireless client device should re-associate from the first AP to a second AP of the wireless network. The first AP communicates an AP coordination message from the first AP to the second AP to share coordination information with the second AP. The first AP coordinates with the second AP to cause the re-association of the wireless client device in accordance with the coordination information. The first and second AP may coordinate directly to synchronize re-association activities. Re-association activities may include the use of a configuration message to the wireless client device, managing transmit power of beacon messages from the first and second APs, or forced disassociation and blocking. The first AP may maintain a record of which re-association activity was successful in causing the wireless client device to re-associate to the second AP.
