Abstract: 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 accelerated service discovery between peer devices. In some embodiments, a wireless device may broadcast a probe beacon on one or more discovery channels. The wireless device may then scan the discovery channels for an extended period of time. The wireless device may receive a response from a peer device and transmit further service information to the peer device in an availability window indicated in the response.

Abstract: Time, frequency and waveform division multiplex schemes are used to efficiently estimate multiple uplink channels in a Wireless Local Area Network (WLAN). Orthogonal Frequency Division Multiple Access (OFDMA) and multi-user Multiple Input Multiple Output (MU-MIMO) approaches provide efficient uplink data transmission. An Access Point (AP) communicates with multiple Stations (STAs) in the WLAN. In some approaches, two or more STAs are addressed and the two or more STAs respond at the same time. The AP receives a composite signal and separates the responses to estimate the uplink channel from each STA. After the AP learns the uplink channels, the AP triggers data transmission from one or more of the WLAN STAs by sending a synchronizing trigger message. In some embodiments, the STAs respond simultaneously with data transmissions to the AP.

Abstract: A wireless device can perform Out-of-Order packet processing and block acknowledgement. Multiple packets may be received at a lower layer of the wireless device. Identifying information may be determined for the received packets. It may be determined that the packets were received out of sequential order, based at least in part on the identifying information. Despite being received out of sequential order, payload information from the packets may be provided to a higher layer of the wireless device in a non-sequential order, such as the order of receipt.

Abstract: An electronic device that determines a transmission schedule is described. This electronic device may include an interface circuit that communicates with a recipient electronic device. During operation, the electronic device may receive a frame with scheduling-request information that is associated with the recipient electronic device. The scheduling-request information may include a buffer status report for persistent traffic, and the frame may be compatible with an IEEE 802.11 communication protocol. For example, the frame may include a scheduling-request management frame. Alternatively, the frame may include a data frame and the scheduling-request information may be included in a media access control (MAC) frame header, such as a high-efficiency (HE) variant high-throughput (HT) control header. Then, the electronic device may determine the transmission schedule based at least in part on the scheduling-request information.

Abstract: The present disclosure describes an electronic device configured to concurrently transmit wake-up radio (WUR) packets in a duplicated WUR transmission mode, non-duplicated WUR transmission mode, and/or mixed WUR transmission mode in one or more channels of a wideband basic service set (BSS) communication. Receiving electronic devices may be grouped together and assigned to monitor for the WUR packets. For example, the receiving electronic devices may be assigned to a position within the one or more channels to monitor for the WUR packets.

Abstract: In some embodiments, one or more wireless stations operate to configure Neighbor Awareness Networking (NAN)—direct communication between neighboring wireless stations, e.g., without utilizing an intermediate access point. Embodiments of the disclosure relate to NAN datapath configuration. 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, scheduler rank management, and further NAN discovery. The datapath model may be implemented for unicast and multicast communication between wireless stations.

Abstract: An interface circuit in a device, e.g., an access point, may perform link adaptation. During operation, the interface circuit may provide a wake-up frame, e.g., a LP-WUR packet, associated with a channel in a band of frequencies, where the wake-up frame is intended for a wake-up radio in a recipient device. Then, the interface circuit may receive, from the recipient device, feedback information associated with a second channel in a second band of frequencies, where the feedback information is associated with a main radio in the recipient device. Based at least in part on the feedback information, the interface circuit may estimate one or more communication metrics associated with the channel in the band of frequencies. Moreover, based at least in part on the one or more communication metrics, the interface circuit may determine a data rate for use in communication via the channel in the band of frequencies.

Abstract: In embodiments, one or more wireless stations operate to configure direct communication with neighboring mobile stations, i.e., direct communication between the wireless stations without utilizing an intermediate access point. Embodiments of the disclosure relate a mechanism for coexistence of various radio access technologies during peer-to-peer communications. In some embodiments, a first communication may be scheduled in one or more time slots with a peer station according to a first radio access technology (RAT), an end time of the first communication during a first time slot of the one or more time slots may be determined, and a second communication according to a second RAT may be transmitted. At least a portion of the second communication may be performed during the first time slot. In some embodiments, the first and second communications may be transmitted on the same channel.

Abstract: In some embodiments, a wireless station may be configured to transmit a request to one or more access points and receive from at least one access point of the one or more access points, a response. The request may be a GAS or probe request and the response may be a GAS or probe response. The request may include an indication of one or more services sought by the wireless station and the response may include information regarding at least one service of the one or more services sought. In addition, the response may be an indication that the at least one access point has determined a match between a provided service and at least one service sought. The wireless station may be further configured to determine, based, at least in part, on the information, to associate with the access point in order to consume the at least one service.
