摘要： An interface circuit in an electronic device may contend for access to a shared communication channel on behalf of the electronic device and a recipient electronic device, where the access has a duration. Then, the electronic device may provide a schedule frame intended for the recipient electronic device that includes information that specifies one or more time slots during the duration that are associated with the recipient electronic device and one or more communication functions of the recipient electronic device in the one or more time slots. Moreover, the electronic device may provide a data frame with data intended for the recipient electronic device. In response, the electronic device may receive a response frame associated with the recipient electronic device, where the response frame is received during at least one of the one or more time slots.

摘要： Disclosed herein are system, method, and computer program product embodiments for indicating a preference to receive a single-user multiple input multiple output (SU-MIMO) or multi-user multiple input multiple output (MU-MIMO) transmission from an access point (AP). Embodiments include generating a standard action frame that contains an action field that species a preference to receive a SU-MIMO or MU-MIMO transmission from the AP. A station (STA) can transmit the generated action frame to the AP. The STA can receive an acknowledgement frame from the AP that indicates the AP is configured to use the requested transmission method. The STA can then receive data from the AP using the requested transmission method.

摘要： 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.

摘要： An apparatus such as a wireless communication device (UE) may include first circuitry configured to conduct wireless communications according to a first radio access technology (RAT) in a first frequency band and in a second frequency band, where the first RAT is a cellular RAT, the first frequency band is in an unlicensed spectrum, and the second frequency band is in a licensed spectrum. The apparatus may include second circuitry configured to conduct wireless communications according to a second RAT in the first frequency band, wherein the second RAT is a wireless local area network (WLAN) RAT. The apparatus may be configured to determine to perform a scan operation in the first frequency band using the first circuitry and, based on one or more transmissions by the second circuitry using the first frequency band, adjust one or more parameters for the scan measurement by the first circuitry. The cellular communications in the first frequency band may be LAA communications, for example.

摘要： A wireless communication device (UE) includes a cellular processor configured to conduct wireless communications according to a first radio access technology (RAT) in a first frequency band and in a second frequency band, wherein the first RAT is a cellular RAT, the first frequency band is in an unlicensed spectrum, and the second frequency band is in a licensed spectrum. In some embodiments, the apparatus includes a wireless local area network (WLAN) processor configured to conduct wireless communications according to a second RAT in the first frequency band. In some embodiments, the cellular processor and the WLAN processor are configured to couple to a common antenna for communications in the first frequency band. In some embodiments, the cellular processor may notify the WLAN processor when it is scanning and/or when it is assigned secondary component carriers in the first frequency band. In some embodiments, the WLAN processor may notify the cellular processor when it is transmitting. In some embodiments, the WLAN processor and/or the cellular processor may perform one or more actions in response to such notifications to improve coexistence in the first frequency band.

摘要： Embodiments of the present disclosure are directed to, among other things, improving data security with respect to data collection, verification, and authentication techniques associated with obtaining and transmitting identity information. For example, an identification credential may be received (e.g., via a short-range communications protocol such as iBeacon) by a first device from a second device. The credential may be associated with a second user of the second device. The first device may verify the credential and, if valid, an additional option to approve a secure communications channel may be presented at the first device. If the additional option is selected, a secure communications channel may be established between the first device and the second device.

摘要： 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.

摘要： 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.
