Abstract: An electronic device (such as an access point) that receives one or more block acknowledgments is described. This electronic device may transmit an extremely high-throughput (EHT) physical layer convergence protocol (PLCP) protocol data unit (PPDU) to a recipient electronic device, where the EHT PPDU is transmitted in multiple non-contiguous sub-bands that are separated by a punctured sub-band. Moreover, the electronic may receive the one or more block acknowledgments from the recipient electronic device, where the one or more block acknowledgments exclude the punctured sub-band. Note that the EHT PPDU may exclude transmitted energy in the punctured sub-band. Moreover, the punctured sub-band may have a bandwidth of at least 20 MHz and may be different from a primary sub-band.

Abstract: An electronic device (such as an access point) that performs a remedial action is described. This electronic device may transmit, using a first radio in the electronic device, a physical layer convergence protocol (PLCP) protocol data unit (PPDU) to a recipient electronic device on a first link between the electronic device and the recipient electronic device, where the PPDU includes a PPDU preamble and a set of media access control (MAC) protocol data units (MPDUs). Then, the electronic device may receive, using a second radio in the electronic device, feedback from the recipient electronic device on a second link between the electronic device and the recipient electronic device. Next, the electronic device may perform the remedial action based at least in part on the feedback. For example, the electronic device may abort the PPDU transmission and/or retransmit one or more of the set of MPDUs.

Abstract: An interface circuit in an electronic device (such as an access point) may provide a targeted wake-up time (TWT) service period (SP) schedule to a recipient electronic device. During operation the interface circuit may receive a TWT setup request associated with the recipient electronic device, where the TWT setup request includes non-availability information specifying one or more times when the recipient electronic device will be unavailable. For example, the non-availability information may include one or more times when the recipient electronic device has limited ability to transmit and/or receive. The interface circuit may provide a TWT setup response for the recipient electronic device, where the TWT setup response includes information specifying the TWT SP schedule for the recipient electronic device that includes at least one of: a TWT SP start time, a TWT SP duration, or an interval between TWT SPs.

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: Some embodiments are directed to grouping electronic devices into contention groups to reduce uplink Orthogonal Frequency-Division Multiple Access (OFDMA) random access (OFDMA-RA) collisions. An access point may explicitly assign an electronic device to a contention group, or the electronic device may implicitly determine an assignment to the contention group. To explicitly assign a device to a contention group, the access point may randomly assign or assign based on a criteria of the electronic device. Examples of criteria include an association identifier (AID), a traffic type/quality of service (QoS) category, a power saving preference, and an association status. The electronic device may implicitly determine a contention group assignment based on the total number of contention groups. The electronic device may use the explicitly or implicitly assigned contention group number to determine whether the electronic device may contend for a given trigger frame random access (TF-R) frame.

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 a mechanism for peer NAN devices to assist one another in receiving communications from an access point common to the peer NAN devices. In some embodiments, a wireless station may establish a communication link with a Wi-Fi access point and establish a peer-to-peer communication link with one or more neighboring wireless stations. In addition, the wireless station may receive transmissions intended for at least one neighboring wireless station of the one or more neighboring wireless stations from the Wi-Fi access point and relay the transmissions to the at least one wireless station on behalf of the Wi-Fi access point.

Abstract: Methods and devices for implementing enhanced probe messaging over a wireless local area network. A user equipment (UE) may transmit a probe request message to a wireless access point (AP) through a wireless local area network (WLAN), wherein the probe request message requests one or more parameters of a response message. The UE may receive the response message as a probe response message or a beacon message from the first AP, and the response message may include information related to one or more basic service sets (BSSs). The information related to the one or more BSSs is determined at least in part based on the requested one or more parameters of the probe request message. The UE may establish a connection with a first BSS of the one or more BSSs based at least in part on the information comprised within the probe response message or the beacon message.

Abstract: An access point may receive, from a set of electronic devices, one or more buffer status reports that indicate that at least a subset of the electronic devices have uplink data associated with one or more access categories. In response, the access point may create a group of uplink virtual queues for one or more electronic devices in the subset based on the one or more buffer status reports, where a given uplink virtual queue corresponds to a particular access category and a given electronic device. The access point may start one or more backoff counters with a one-to-one correspondence to uplink virtual queues in the group of uplink virtual queues. When a backoff counter for the given uplink virtual queue reaches zero, the access point may transmit a trigger frame to an electronic device in the subset that corresponds to the given uplink virtual queue.

Abstract: During operation, an interface circuit in an electronic device may receive, from a second electronic device (such as an access point in a WLAN), an uplink trigger frame that may specify an access category. In response to the uplink trigger frame, the electronic device may first include data associated with the specified access category in one or more frames, and then may transmit the one or more frames to the second electronic device. Moreover, when all the data associated with the specified access category has been transmitted or when there is no data associated with the specified access category, and when there is leftover time in an allocation associated with the uplink trigger frame, the interface circuit may transmit the one or more frames to the second electronic device with additional data associated with another access category that is different from the specified access category.
