  • Publication number: 20180324701
    Abstract: Methods, systems, and devices for wireless communication are described. An access point (AP) may broadcast or multicast a wakeup transmission to wakeup radios (WURs) of a group of wireless and determine to retransmit the first wakeup transmission (e.g., for redundancy). The AP may transmit a second wakeup transmission to the WURs, the second wakeup transmission including an indication that the second wakeup transmission is a retransmission of the first wakeup transmission. The wireless devices may receive the indication that the second wakeup transmission is a retransmission, and may power up a main radio to receive a beacon based on whether or not the previous or originally wakeup transmission was received (e.g., determined via the indication included in the received wakeup message). In some cases, the AP may identify that some wireless devices failed to receive the first wakeup transmission, and may transmit a second wakeup transmission to those identified stations.

  • Publication number: 20180317245
    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).

  • Publication number: 20180295595
    Abstract: An access point (AP) may determine a time resolution for values indicative of wakeup signal transmission times based on a wakeup schedule of a station (STA) and a clock drift value for the STA and may transmit, to a primary radio of the STA, an indication of the time resolution. The AP may identify a transmission time of a wakeup signal for the STA and determine a value indicative of the transmission time. The AP may transmit, to a wakeup radio of the STA, the wakeup signal as a packet that includes the value indicative of the transmission time. The STA may determine the transmission time of the wakeup signal based on the wakeup schedule, the indication of the time resolution, and the value indicative of the transmission time and may update a local clock timing based on the transmission time.

  • Patent number: 10098083
    Abstract: Methods, systems, and devices are described for dealing with mutual clock drifts for communications over multiple RATs by maintaining a guard interval. A guard interval is a time interval during which no transmissions should occur. For example, the guard interval may be set relative to a scheduled interference interval of a STA so that transmissions to the STA from an AP will not collide with different RAT (e.g., interference) transmissions/receptions even with clock drift (e.g., a guard interval at both sides of the scheduled interference interval). Such an approach may allow the clocks to be re-synchronized (e.g., by the STA notifying the AP of the schedule of interference interval) infrequently to avoid excessive signaling overhead, which would increase with an increase in the number of coexistence STAs being serviced by the AP.

  • Publication number: 20180288703
    Abstract: A wireless device may identify a transition from use of a main radio to use of a wakeup radio (WUR) of the wireless device is to occur. The wireless device may store the power state the main radio is operating in at the time of the transition. The wireless device may then power down the main radio and power up the WUR to perform the transition. Upon a transition back to use of the main radio from use of the WUR (e.g., in response to a wakeup transmission), the wireless device may power down the WUR and power up the main radio to the stored power state. Additionally, the wireless device may further store WUR power state information, such that upon exit and reentry of WUR operation, the wireless device may resume a previously used WUR power mode. Modified or newly defined uplink frames may indicate such power state transitions.

  • Patent number: 10091682
    Abstract: Methods, systems, and devices for wireless communication are described. Methods, systems, and devices provide for determining or identifying a client device that is monopolizing a channel associated with a first basic service set (BSS). Once identified, a second BSS is dynamically created and configured with parameters that are throttled with respect to the first BSS. The client device is steered to the second BSS and is prevented from reassociating with the first BSS until a change in device status.

  • 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: 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: 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.
