Abstract: An interface circuit in an electronic device (such as an access point) may receive a setup request associated with the recipient electronic device. The setup request may specify a group address for which the recipient electronic device wants to receive associated frames and a proposed transmission interval. Based at least in part on the proposed transmission interval, the electronic device may determine a transmission schedule and/or may assign, based at least in part on the group address, the recipient electronic device to an aggregated group having a flexible multicast service identifier (FMSID). Then, the electronic device may provide a wake-up frame for the recipient electronic device, where the wake-up frame includes an identifier of the aggregated group for which a group-addressed frame will subsequently be transmitted by the electronic device. Moreover, the wake-up frame may be provided at a transmission time based at least in part on the transmission schedule.

Abstract: During operation, an electronic device may encrypt an A-control subfield. Then, the electronic device may provide the frame addressed to a second electronic device, where the frame includes a media access control (MAC) header and the MAC header includes the A-control subfield that is encrypted. Note that the encrypted A-control subfield may be jointly encrypted with data in a payload in the frame. Moreover, the encrypted A-control subfield may be separated from the payload in the frame by one or more additional subfields or may be adjacent to the payload in the frame. Furthermore, the MAC header may include an indicator that indicates whether the A-control subfield is encrypted. Additionally, the frame may include a preamble that indicates whether the A-control subfield is encrypted. The frame may be received by the second electronic device. After receiving the frame, the second electronic device may decrypt the A-control subfield.

Abstract: Embodiments described herein relate to a system and method for providing flexible receiver configuration in wireless communication systems, such as 802.11 WLAN systems. In one embodiment, a wireless device may transmit a first data frame including first configuration information specifying a first configuration of the receiver to notify a remote device that the wireless device intends to configure its receiver according to the first configuration. After receiving an acknowledgement frame confirming the first configuration information, the wireless device may configure the receiver according to the first configuration. In another embodiment, a wireless device may receive a first data frame including first configuration information and further including a request that the wireless device configure its receiver according to the first configuration. In response, the wireless device may configure the receiver according to the first configuration. In either case, the wireless device may receive subsequent communications according to the first configuration.

Abstract: One or more wireless stations may operate to configure Neighbor Awareness Networking (NAN)—direct communication with neighboring wireless stations, e.g., without utilizing an intermediate access point. Scheduling of NAN ranging procedures may include a first wireless station sending first information, including first scheduling preferences and a first ranging role, to a second wireless station. The first wireless station receives second information, including second scheduling preferences and a second ranging role, from the second wireless station. The first wireless station may initiate the ranging procedure based on the scheduling preferences and ranging parameters. Alternatively, the second wireless station and may initiate the ranging procedure based on the scheduling preferences and ranging parameters.

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: 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.
