摘要： An electronic device (such as an access point) may provide a management frame, intended for at least a recipient electronic device, that includes slotted-operation information corresponding to a power-save mode of the electronic device for communication with at least the recipient electronic device. The slotted-operation information may include a sequence of temporal slots and associated channel information for the temporal slots. When a channel for a temporal slot comprises a null value, the power-save mode may include transitioning the electronic device into a lower-power-consumption mode during the temporal slot. Alternatively, when a channel for a temporal slot is different than a null value, the power-save mode may include performing another activity than communicating with the recipient electronic device during the temporal slot.

摘要： Some aspects of this disclosure relate to apparatuses and methods for implementing wireless devices. A service is provided by a first application operating on a publisher device to a second application operating on a subscriber device over a first data path between the two devices in a NAN network. The publisher device includes a first recovery manager to receive an indication from a wireless controller of the publisher device or a distress message from a second recovery manager of the subscriber device. The received indication or distress message indicates that the first data path has been interrupted. The first recovery manager stores, in a memory, data generated by the first application. A second data path is established between the publisher device and the subscriber device. The first recovery manager sends the stored data to the second application that operates on a subscriber device.

摘要： An apparatus comprises a memory and at least one processor in communication with the memory. The at least one processor is to detect, during a discovery window, a neighboring client station that is to perform peer-to-peer Wi-Fi communication via a Neighbor Awareness Networking (NAN) protocol and establish, via a negotiation after the discovery window, a datapath with the neighboring client station, wherein the negotiation includes an exchange of NAN data path setup attributes in parallel with an exchange of encryption cipher attributes and the encryption cipher is based on a simultaneous authentication of equals (SAE) protocol. The SAE protocol can be used to generate key material to encrypt the datapath.

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： This disclosure relates to methods for conducting multilink communications between a user equipment (UE) device and a remote device over a wireless local area network (WLAN). The UE device periodically transmits communications to the remote device over a first frequency band on the WLAN using a first radio. The UE device may determine to switch from transmitting communications to the remote device over the first frequency band to transmitting said communications over a second frequency band. The UE device then transmits communications to the remote device over the second frequency band on the WLAN.

摘要： Methods and apparatus for an electronic device to perform a dynamic frequency selection (DFS) proxy function are described. An interface circuit of the electronic device receives, from an access point associated with the electronic device, a frame with DFS information that indicates a presence of interference associated with a higher priority user in a shared band of radio frequencies. The frame can include an action frame with a channel switch announcement (CSA) or a beacon with a CSA. In response to receiving the DFS information, the electronic device forwards, to a third electronic device, the DFS information, where the third electronic device is not associated with and does not have a connection to the access point. In this way, the electronic device functions as a DFS proxy for the third electronic device with respect to the shared band of radio frequencies used by the access point.

摘要： 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 adapting a signal strength metric threshold. In some embodiments, the signal strength metric may be adapted (or adjusted) to establish or maintain data communications with peer devices.

摘要： One or more wireless stations may operate to configure direct communication with neighboring mobile stations, e.g., direct communication between the wireless stations without utilizing an intermediate access point. A mechanism for a wireless station to transmit a paging beacon outside of a paging window may include establishing a paged data link with a peer station, determining that one or more data frames associated with the paged data link are pending transmission, and transmitting a beacon to the peer station outside of a scheduled paging window of the paged data link. The beacon may include a paging attribute indicating there are pending data frames.

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.
