    Abstract: In some embodiments, one or more wireless stations operate according to Neighbor Awareness Networking (NAN)—direct communication with neighboring wireless stations, e.g., direct communication between the wireless stations without utilizing an intermediate access point. Embodiments of the disclosure relate to triggering a NAN datapath using Bluetooth low energy (BLE) signaling. The NAN datapath embodiments described herein provide a mechanism through which devices can communicate to establish a Wi-Fi connection via non-Wi-Fi signaling and provide services. Aspects of the datapath development include Wi-Fi connection establishment and datapath initiation. The datapath model may be implemented for unicast and/or multicast communication between wireless stations, including mobile stations.

    Abstract: This disclosure relates to techniques for access control operation between devices in a wireless communication system. An access device may store reader group identifier information for one or more reader devices. The access device may receive an advertisement indication from a reader device in a wireless manner. The advertisement indication may include a reader group identifier for the reader device. The access device may determine that the reader group identifier information stored by the access device includes the reader group identifier indicated by the reader device. The access device may attempt to perform access control communication exchange with the reader device based at least in part on determining that the reader group identifier information stored by the access device includes the reader group identifier indicated by the reader device.

    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: Methods and apparatuses for managing coexistence of multiple wireless devices that share a radio frequency band and communicate with a wireless network device. The wireless devices include both wireless personal area network (WPAN) and wireless local area network (WLAN) devices. The wireless network device monitors data activity for WPAN devices to determine whether the WPAN devices are active or inactive, and sets one or more polling intervals for the WPAN devices accordingly. The wireless network device consolidates polling for multiple WPAN devices into a common WPAN polling time period and sends a radio frequency (RF) reservation request to a WLAN access point (AP), the RF reservation request including an indication of a duration for the common WPAN polling time period, during which the multiple WPAN devices are polled. WLAN data packet transmission is delayed during the common WPAN polling time period to mitigate coexistence interference.

    Abstract: In embodiments, one or more wireless stations operate to configure direct communication with neighboring mobile stations, i.e., direct communication between the wireless stations without utilizing an intermediate access point. Embodiments of the disclosure relate a mechanism for coexistence of various radio access technologies during peer-to-peer communications. In some embodiments, a first communication may be scheduled in one or more time slots with a peer station according to a first radio access technology (RAT), an end time of the first communication during a first time slot of the one or more time slots may be determined, and a second communication according to a second RAT may be transmitted. At least a portion of the second communication may be performed during the first time slot. In some embodiments, the first and second communications may be transmitted on the same channel.
