    Abstract: Methods and apparatus for dynamic, adaptive scanning of communication channels are provided. A device alternates between scan cycles and rest cycles. A scan cycle includes interleaved intervals of scanning and resting. A scan interval may involve active or passive scanning, and a rest interval may be active or inactive. An active rest interval is spent tending to a communication requirement other than scanning (e.g., an infrastructure connection, a peer-to-peer connection). An inactive rest interval may be spent in a low-power mode of operation. Rest cycles, like rest intervals, may also be active or inactive. Durations of rest cycles and rest intervals increase each time a scan cycle completes without detection of any significant event or signal (e.g., until they reach a maximum). Upon detection of a significant event, they decrease, possibly by being reset to default durations.

    Abstract translation: 提供了通信信道的动态，自适应扫描的方法和装置。 一个设备在扫描周期和休息周期之间交替。 扫描周期包括扫描和休息的交错间隔。 扫描间隔可以涉及主动或被动扫描，并且休息间隔可以是活动的或不活动的。 除了扫描（例如，基础设施连接，对等连接）之外，主动休息间隔用于趋向于通信要求。 不活动的休息间隔可以用在低功率操作模式中。 休息周期，如休止间隔，也可能是活动或非活动。 每次扫描周期完成，休息周期和休息间隔的持续时间都会增加，而不会检测到任何重大事件或信号（例如，直到达到最大值）。 在检测到重大事件时，它们可能会被重置为默认持续时间。

    Abstract: Techniques are described for multi-layer interference detection. The method can include transmitting data to a system using a connection on a wireless network, the system configured to provide access to a functionality of a device. The method can further include accessing at least one of link quality monitoring (LQM) information from a medium access control layer of the user device or transmission control protocol (TCP) information from a transport layer of the device during a presentation of data by the system. The method can further include determining that the wireless network is experiencing interference based at least in part on the LQM information or TCP information. The method can further include generating interference information based at least in part on determining that the wireless network is experiencing the interference. The method can further include transmitting the interference information to the system during the presentation of data by the system.

    Abstract: An interface circuit in an electronic device (such as an access point) may provide a targeted wake-up time (TWT) service period (SP) schedule to a recipient electronic device. During operation the interface circuit may receive a TWT setup request associated with the recipient electronic device, where the TWT setup request includes non-availability information specifying one or more times when the recipient electronic device will be unavailable. For example, the non-availability information may include one or more times when the recipient electronic device has limited ability to transmit and/or receive. The interface circuit may provide a TWT setup response for the recipient electronic device, where the TWT setup response includes information specifying the TWT SP schedule for the recipient electronic device that includes at least one of: a TWT SP start time, a TWT SP duration, or an interval between TWT SPs.

    Abstract: In embodiments, one or more wireless stations operate to configure direct communication with neighboring mobile stations, i.e., direct communication between the mobile 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. In particular, embodiments described herein provide a mechanism for NAN datapaths to support various levels of quality of service (QoS). 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 wireless stations.
