Abstract: A dual-radio AP including both a high-power (e.g., Wi-Fi) radio and a low-power (e.g., BLE) radio may support an assisted wakeup service for a power-limited dual-radio mobile device (STA). The power-limited STA may register with the AP for the assisted wakeup service, and may then disable its Wi-Fi radio (or otherwise initiate a lower-power mode). The power-limited STA may receive a BLE communication indicating the AP has pending Wi-Fi transmissions or updates applicable to the power-limited STA. In response, the power-limited STA may turn on its Wi-Fi radio and receive the pending transmissions or updates from the AP. If an AP does not include a low-power radio, then a high-power/low-power dual-radio STA that is not power-limited may serve as an assisted wakeup service proxy. The proxy may scan and trace the Wi-Fi beacons from the AP, and generate the BLE communication to the power-limited STA on behalf of the AP.

Abstract: In one set of embodiments, one or more client stations operate to configure Neighbor Awareness Networking (NAN)—direct communication with neighboring client stations, i.e., direct communication between the client stations without utilizing an intermediate access point. Embodiments of the disclosure relate to NAN datapath scheduling and NAN pre-datapath operation setup and scheduling. The NAN datapath embodiments described herein provide a mechanism through which devices can communicate and provide services. Aspects of the datapath development include datapath scheduling, including datapath setup and scheduling attributes, as well as pre-datapath operation triggering and scheduling. Scheduling may include determination of a type of datapath, including paging and synchronized datapaths. NAN data cluster base schedules may be scheduled as equal-sets or subsets of datapath schedules. The datapath model may be implemented for unicast and multicast communication between client stations.

Abstract: Antenna diversity for beacons. An access point device may include multiple antenna arrays. A series of beacons may be transmitted using each of the antenna arrays in sequence. The beacons may include configuration information usable by wireless devices to determine when to respond to the beacons. The access point may receive responses during a series of response periods, using each of the antenna arrays.

Abstract: In some embodiments, one or more wireless stations operate to configure direct communication with neighboring mobile stations, e.g., direct communication between the wireless stations without utilizing an intermediate access point. Embodiments of the disclosure relate to a mechanism for a wireless station to discover a neighboring peer wireless station, e.g., via peer-to-peer Wi-Fi communications, receive a synchronization beacon(s) from the neighboring peer wireless station, and synchronize timing with the neighboring peer wireless station based at least in part on the synchronization beacon(s). In addition, the wireless station may transmit, e.g., via Wi-Fi peer-to-peer communications, a data beacon to one or more neighboring wireless devices stations, wherein the one or more neighboring wireless stations are configured to synchronize timing with the wireless station based on the data beacon.

Abstract: In some embodiments, one or more wireless stations operate to configure direct communication with neighboring mobile stations, e.g., direct communication between the wireless stations without utilizing an intermediate access point. Embodiments of the disclosure relate to a mechanism for a device to trigger, via a first interface, service discovery over a second interface. In some embodiments, the service discovery can involve the exchange of one or more Bloom filters.

Abstract: In embodiments, a wireless device, such as a Wi-Fi device, transmits communication signals on secondary channels within an operational bandwidth of a wireless network, concurrent with a transmission from another wireless device on a primary channel. The wireless device may detect that a first frequency band within an operating bandwidth of a wireless network is occupied by a first transmission transmitted by a second wireless device, and determine that a second, different frequency band within the operating bandwidth of the wireless network is not occupied. In response, the wireless device may transmit a second transmission occupying the second frequency band concurrent with the first transmission. The wireless device may set a duration of the second transmission based at least in part on a determination of whether the second wireless device is configured to assess the state of all frequency bands within the operating bandwidth before beginning a subsequent transmission.

Abstract: Embodiments described herein relate to providing reduced power consumption in wireless communication systems, such as 802.11 WLAN systems. Timing information regarding power save opportunities (PSOPs) may be provided in communication frames, which may inform mobile devices of expected frame exchange periods during which they may transition to a Doze state. Additional PSOP information may be included in beacon frames, which may inform mobile devices of expected multicast periods during which they may transition to a Doze state. This may operate to provide improvements in terms of power consumption.
