Abstract: In some embodiments, a first wireless device initializes a first threshold and sends a first frame transmission to a second wireless device. When the first wireless device determines that the first frame transmission was successful, it adjusts the first threshold to a second threshold that is greater than the first threshold. Additionally, when the first wireless device determines that the first frame transmission was not successful, the first wireless device adjusts the first threshold to a third threshold that is less than the first threshold. The thresholds can be associated with any measure, including carrier sensitivity and/or energy detection.

Abstract: A wireless access point transmits a protocol data unit (PDU) that includes data and signaling for a plurality of user devices. The PDU spans a channel in frequency and an interval in time, and includes a first signaling section, a second signaling section and a traffic action. For each of a plurality of subchannels of the channel: the first signaling section includes (within the subchannel) a corresponding redundant copy of common signaling information for the user devices associated with the access point; the second signaling section includes (within the subchannel) a corresponding set of user-specific signaling information for a corresponding group of one or more of the user devices; and the traffic section includes (within the subchannel) a corresponding set of traffic data for the corresponding group of one or more user devices. Subchannels sizes may be configurable. A signaling set CRC may be included per subchannel.

Abstract: The disclosed embodiments provide a system that enables service-configurable wireless connections. During operation, a local service endpoint of a service runs on a wireless device. The local service endpoint sends a request to establish a datapath with another service endpoint on another device. Meanwhile, the wireless device's service discovery module discovers a remote endpoint for the service on a remote device. In response to the request, the wireless device's service-configurable security entity configures a Wi-Fi connection's security configuration, thereby enabling the local endpoint to establish a datapath between the local endpoint and the remote endpoint over the Wi-Fi connection.

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.

Abstract: Some embodiments of this disclosure include apparatuses and methods for implementing discovery frames and group addressed frames communication. For example, some embodiments relate to a method including generating a first frame to be transmitted to a first electronic device. An association identifier (AID) value of the first frame is set to a first value to indicate that the first frame is an individually addressed frame addressed to the first electronic device. The method further includes generating a second frame to be transmitted to a group of one or more electronic devices. An AID value of the second frame is set to a second value different from the first value. The method also includes transmitting the first frame and the second frame.

Abstract: Some aspects of this disclosure include apparatuses and methods for implementing backup link establishment and operation for multi-link wireless communication networks such as a wireless local area network (WLAN). Some aspects relate to an electronic device including a transceiver configured to communicate over a wireless network and a processor communicatively coupled to the transceiver. The processor receives a message including information associated with a backup link from a second electronic device. The processor further receives data associated with data traffic from the second electronic device on a primary link of the wireless network. In response to a quality of the primary link being below a threshold, the processor receives a notification frame from the second electronic device on the backup link and receives additional data associated with the data traffic from the second electronic device on the backup link or on an other link informed by the notification frame.
