  • Publication number: 20190141620
    Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for receiving scanning information from a second wireless communication device over a wireless link associated with a first wireless communications protocol, the scanning information identifying one or more wireless frequency channels associated with a second wireless communications protocol; selecting a subset of wireless channels associated with the second wireless communications protocol based on the scanning information; and scanning one or more wireless frequency channels of only the selected subset of wireless frequency channels.

  • Patent number: 9807540
    Abstract: Methods, systems, and devices are described for peer-to-peer (P2P) group owner (GO) multi-channel concurrent (MCC) operation and an associated absence period indication for legacy client devices. In some aspects, an absence period during which a peer-to-peer (P2P) group owner (GO) is unavailable to receive transmissions from client devices wirelessly coupled with the P2P GO may be identified. A notice of absence (NoA) may be transmitted by the P2P GO, the P2P NoA indicating the absence period if the client devices wirelessly coupled with the P2P GO include a P2P client device that supports a P2P protocol. A legacy wireless beacon may be transmitted by the P2P GO, the legacy wireless beacon comprising an information element (IE) indicating the absence period if the client devices wirelessly coupled with the P2P GO include a legacy client device that does not support the P2P protocol.

  • Patent number: 9730162
    Abstract: Methods, systems, and devices are described for using low energy (LE) signaling to indicate to a wireless station (STA), prior to transmission of a beacon, whether the beacon will further indicate that an access point (AP) has data to transmit to the STA. In one aspect, a method may include receiving, using a first radio of a wireless STA using a LE communication protocol, a first signal comprising an indication of a traffic indication map (TIM) of a wireless local area network (WLAN) beacon, and selectively powering up a second radio of the wireless STA to receive the WLAN beacon in response to the indication. In one aspect, the wireless STA may power up the first radio at a predetermined interval prior to a target beacon transmission time (TBTT) of the WLAN beacon.

  • Publication number: 20160112947
    Abstract: A method and apparatus are disclosed for reducing power consumption of wireless devices operating in a wireless network. In one embodiment, a first wireless device may establish a BLUETOOTH low energy (BLE) connection and a Wi-Fi connection with a second wireless device. The first wireless device may detect Wi-Fi activity and may operate in a low-power mode when no Wi-Fi activity is detected. The first wireless device may receive a synchronized BLE message and may enter a normal operating mode and leave the low-power mode based, at least in part, on the synchronized BLE message. In another embodiment, the first wireless device may operate a scheduler to schedule communications between the second wireless device and a third wireless device. The first wireless device may suspend operation of the scheduler based, at least in part, on a received synchronized BLE message from the second wireless device.

In one embodiment, a first wireless device may operate in low-power mode and receive a BLUETOOTH low energy (BLE) message from a second wireless device. The first wireless device may leave the low-power mode and enter a normal operating mode based, at least in part, on the BLE message. In some embodiments, the BLE message may include informational elements that the first wireless device may use to determine whether to remain in or leave the low-power mode. In some other embodiments, the BLE message may be synchronized to a Wi-Fi message, such as a Wi-Fi beacon. In at least one embodiment, the first wireless device may stop scanning for wireless networks when in the low-power mode.
