  • Patent number: 11765698
    Abstract: An electronic device that communicates with a second electronic device is described. During operation, an electronic device communicates first messages with the second electronic device in time slots corresponding to first channels in a first band of frequencies using a peer-to-peer communication protocol (such as neighbor awareness networking or NaN), where, in a given time slot, a given first channel in the first band of frequencies is used in the communication of the first messages. Moreover, the electronic device communicates second messages with the second electronic device in the time slots corresponding to second channels in a second band of frequencies using the peer-to-peer communication protocol, where, in the given time slot, a given second channel in the second band of frequencies is used in the communication of the second messages. Note that the communicating of the first messages and the second messages may at least partially overlap in time.

  • Patent number: 11765707
    Abstract: 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.

  • Patent number: 11743714
    Abstract: 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.

  • Patent number: 11700603
    Abstract: Some embodiments include an apparatus and method for enabling concurrent peer-to-peer (P2P) communications via a scheduled resource unit (RU) allocated by an access point (AP). For example, the AP may use a trigger frame to schedule uplink (UL) multi-user (MU) access for a first station of a plurality of stations by allocating an RU to the first station. Instead of using the allocated RU for UL infrastructure communications with the AP, the first station may utilize the allocated RU for a P2P communications with a second station. In some embodiments the AP facilitates RU utilization for P2P communications between stations. In some embodiments, the first station uses the allocated RU and the AP may be unaware of the P2P communications.

  • Patent number: 11671259
    Abstract: 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.

  • Publication number: 20220353682
    Abstract: 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. A wireless station may enter an unsynchronized discovery mode, transmit, in response to receiving a subscribe message from a neighboring device, a publish message to the neighboring device, perform authentication and trusted device cluster provisioning with the neighboring wireless device, and protect transmissions using the security credentials. In the unsynchronized discovery mode, the wireless device may monitor a discovery channel for subscribe messages, e.g., from neighboring peer devices. Additionally, the trusted device cluster provisioning may provide security credentials to the wireless device.

  • Publication number: 20220007281
    Abstract: 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.

  • Patent number: 11212806
    Abstract: 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. A wireless station may determine a further availability window schedule for a first time period, including specifying availability for particular channels at particular time slots at a first time slot increment. The wireless station may specify availability at a second time slot increment for a subset of the time slots specified at the first time slot increment. The second time slot increment may be less than the first slot time increment. The wireless station may negotiate, with a neighboring wireless station, a peer-to-peer communication schedule for the peer-to-peer communication application based on the further availability window schedule, including specifying a portion of the peer-to-peer schedule using the second time slot increment.
