Abstract: An electronic device that communicates frames is described. During operation, the electronic device may transmit the frames addressed to a recipient electronic device and associated with multiple links between the electronic device and the recipient electronic device. Then, the electronic device may receive block acknowledgments for at least a subset of the frames, where a given block acknowledgment is associated with the recipient electronic device and indicates received frames on a given link in the links. Moreover, the electronic device may control an amount of traffic conveyed on the links based at least in part on the block acknowledgments. Next, the electronic device may store a remainder of the frames based at least in part on the block acknowledgments, where the frames include the subset of the frames and the remainder of the frames. Note that the frames may have a common traffic identifier.

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: This disclosure relates to methods for conducting multilink communications between a user equipment device (UE) and a wireless access point (AP) over a wireless local area network (WLAN). The UE establishes a connection with an access point through a WLAN, wherein the connection utilizes a plurality of links. The UE transmits an indication to the access point through a first link of the plurality of links, where the indication specifies one or more available links of the plurality of links that are available for the UE to receive downlink (DL) communications from the access point. The UE receives one or more DL communications from the access point through at least one of the one or more available links.

Abstract: In some embodiments, one or more wireless stations operate to configure direct communication with neighboring wireless stations, e.g., direct communication between the wireless stations without utilizing an intermediate access point. Embodiments of the disclosure relate to a mechanism for a device to transmit, via a BTLE (or Bluetooth) interface, a first message indicating an operation associated with a Wi-Fi service (e.g., a service available via a Wi-Fi interface and/or Wi-Fi related interface parameters) to a peer device. The first message may include a service hash that indicates the operation. The service hash may be included in a first data structure. The first data structure may indicate availability of the Wi-Fi service. The device may receive a second message from the peer device indicating that the neighboring wireless station intends to subscribe to or provide the Wi-Fi service, e.g., via Wi-Fi peer-to-peer communications.

Abstract: A method for receiving feedback on a quality of multicast transmissions in a Wireless Local Access Network (WLAN) including a source electronic device (e.g., an access point) and a plurality of electronic devices is disclosed, according to some embodiments. The method can include (i) transmitting a plurality of multicast packets addressed to a subset of the plurality of electronic devices by the source electronic device; (ii) concurrently polling the subset of the plurality of electronic devices by the source electronic device; and (iii) receiving a plurality of block acknowledgements (BAs) from at least the subset of the plurality of electronic devices by the source electronic device. Each BA may include information on a quality of reception of two or more multicast packets received at an electronic device.

Abstract: Disclosed herein are system, method, and computer program product embodiments for enabling a spatial reuse opportunity at a high efficiency (HE) station and a network allocation vector (NAV) reset capability at a legacy station using a Request to Send and/or Clear to Send (RTS and/or CTS) frame. For example, the method can include receiving a RTS frame with a redefined field that specifies spatial reuse information. The NAV can be set based on the RTS frame. The method can determine whether a second frame was received within a threshold time after a Short Interframe Space (SIFS). Finally, the method can reset the NAV based on whether the second frame was received within the threshold time.

Abstract: An interface circuit in an electronic device may receive, from an access point associated with the electronic device, a frame with management information that enables the electronic device to use a spatial-reuse technique, where the electronic device, through the spatial-reuse technique, adjusts a transmit power and a channel-availability sensing threshold. Moreover, the management information may specify parameters for the spatial-reuse technique. Then, the electronic device may transmit, using the spatial-reuse technique, one or more frames to the access point based on the parameters. Furthermore, the electronic device may transmit, to the access point, feedback information that indicates communication performance during the communication between the electronic device and the access point. For example, the feedback information may include a retry rate and, more generally, communication-performance information. This feedback information may be used by the access point to modify the parameters.

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.
