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: A station, a method performed by a station and a corresponding method performed by an access point (AP) of a network to allow the station to operate a wireless local area network (WLAN) radio in a sleep state until the WLAN radio is ready to receive a beacon from the AP. The station includes a low power (LP) radio configured to receive a wake up signal from an AP of a network to which the station is connected. The station further includes a WLAN radio configured to operate in a sleep state until the WLAN radio receives an indication from the LP radio that the wakeup signal has been received, wherein WLAN radio is further configured to operate in a fully awake state after receipt of the indication to receive a beacon from the AP indicating a data transmission is pending for the station.

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: 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: An electronic device that transmits a frame to a second electronic device is described. In particular, during operation, an interface circuit in the electronic device (such as an access point in a WLAN) may transmit the frame to the second electronic device using a Wi-Fi communication protocol. The frame may include information cancelling a previously specified NAV protected time in a preamble of the frame. For example, the information may include a CF-End indication. Moreover, the information may be included in a MAC header of the frame and, more generally, in a preamble of a high efficiency (HE) physical layer convergence protocol (PLCP) protocol data unit (PPDU). Furthermore, the electronic device may transmit the frame in response to a block acknowledgment (BA) from the second electronic device.

Abstract: 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 wireless stations to learn preferred channels of neighboring wireless stations and to schedule channel sequences within a time period based on the learned channels may include advertisement of preferred channels and adaptation of channel sequences, based on the preferred channels, to maximize bandwidth utilization.

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.
