Abstract: In one aspect, a method includes: transmitting, from a transmitter, a first packet to a device wirelessly coupled to the transmitter; in response to not receiving a response regarding the first packet from the device, retransmitting the first packet until a response is received; transmitting a plurality of second packets to the device, the second packets having a smaller width than the first packet; identifying a periodic polling interval at which the device communicates with another device; and adjusting a transmit clock slot and transmitting one or more third packets to the device according to the adjusted transmit clock slot.

Abstract: This disclosure provides methods, devices and systems for neighbor awareness networking extension to 6 GHz networks. A method is provided that may be performed by a wireless communication device. The wireless communication device discovers one or more peer devices in a neighborhood aware network (NAN) on a first radio frequency band. The wireless communication device discovers a capability of at least one of the one or more peer devices for communicating on a 6 GHz radio frequency band and/or publishes a capability of the wireless communication device for communicating on the 6 GHz radio frequency band. The wireless communication device establishes a NAN device link with the at least one peer device on the 6 GHz radio frequency band.

Abstract: The disclosure relates to techniques to extend the time that wireless devices spend in a sleep state. For example, a first wireless device may transmit a poll message to a second wireless device during a current polling period having multiple polling slots allocated to transmissions by the first wireless device. In response to receiving a null response message while there are one or more remaining polling slots allocated to transmissions by the first wireless device, the first wireless device may terminate the current polling period early. Furthermore, an early termination message may be transmitted to the second wireless device to indicate that the first wireless device will not be sending any further transmissions in the current polling period. As such, both wireless devices may then place one or more electronic circuits into a low-power mode prior to a sleep period scheduled to start when the current polling period ends.

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.

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.

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.

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.

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 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.

Abstract: The listen interval of a WLAN client is selected to have one of a plurality of values, including a start listen interval (SLI) and one or more longer listen intervals (e.g., transient listen interval (TLI), maximum listen interval (MLI)). The listen interval is set to SLI in response to (1) detecting that an applications processor of the WLAN client is in an awake state, (2) detecting transmit/receive activity on the wireless link, and (3) failing to detect an expected beacon signal on the wireless link. If the listen interval is set to MLI (or TLI) and the WLAN client fails to detect an expected beacon signal (beacon miss), the listen interval is temporarily set to SLI. If the WLAN client then detects an expected beacon signal before detecting a predetermined number of consecutive beacon misses, the listen interval is immediately returned to the original listen interval MLI (or TLI).
