Abstract: Systems and methods are provided for opportunistic spatial reuse. In various embodiments, the disclosed systems and methods provide for mechanisms for enabling and disabling spatial reuse in a wireless network as appropriate based on the deployment of the wireless network. In some embodiments, spatial reuse can be enabled and disabled based on various factors, such as channel utilization. In some embodiments, spatial reuse can be enabled and disabled as appropriate for various types of traffic in a wireless network. For example, spatial reuse can be enabled and disabled for downlink traffic (e.g., traffic from an access point to a client device), for uplink traffic (e.g., traffic from a client device to an access point), for multicast or broadcast traffic (e.g., traffic distributed to multiple recipients), or for certain modes of transmission (e.g., single user beamformed transmission, Dual Carrier Modulated transmission).

Abstract: Systems and methods are configured to receive a first request to schedule a Time To Wake (TWT) service period (SP) for a first station. The first request can be based on individual TWT protocol. That the TWT SP satisfies a threshold level of similarity with an existing TWT SP maintained for a group of at least one station scheduled to communicate over the existing TWT SP can be determined. The group can include a second station. The first station can be assigned to the group. A first packet can be transmitted to the first station and a second packet can be transmitted to the second station over the existing TWT SP.

Abstract: Systems and methods are provided for optimizing the scheduling of Orthogonal Frequency-Division Multiple Access (OFDMA) transmissions in the downlink (DL) direction. A two-stage mechanism can be implemented when effectuating DL OFDMA transmission involving multiple modulation and coding schemes (MCS) in a single transmit burst. A first stage of the two-stage mechanism may use radio frequency (RF) boosting/de-boosting of Resource Units (RUs) such that the average input power to an AP power amplifier (PA) may remain under a saturated PA output power to ensure PA linearity. If RF boosting/de-boosting is not supported, an alternative mechanism for OFDMA grouping (to rigid grouping) can be employed to skip higher MCS.

Abstract: Examples described herein provide wake-up of a network device. Examples include receiving, by a network interface of a first network device having a first Media Access Control (MAC) address, a request to wake-up a second network device having a second MAC address that is assigned to a same subnet as the first MAC address, and in response to the request, generating, by the first network device, a first wake-up frame having a destination address of the second MAC address and configured to cause the second network device to transition from operating in the first power mode to operating in the second power mode. Examples include transmitting, by the network interface of the first network device, the first wake-up frame to the second MAC address of the second network device.

Abstract: A system and method for optimizing a channel sounding procedure of a multi-link device (MLD) is disclosed. The improved channel sounding procedure disclosed herein involves an MLD requesting channel sounding information from a group of receivers on a first channel representing a first physical frequency, but receiving channel sounding information from a subgroup of the receivers on one or more other channels representing different physical frequencies. In this manner, the channel sounding procedure on a specific link of an MLD is optimized by offloading some of the sounding process to a different radio link that is also operational for the MLD as part of the same association context.

Abstract: Systems and methods for power save aware resource unit allocation include sending, by an access point to a station, a beacon indicating that the station has data buffered at the access point, wherein the station is in a power-save mode, sending, by the access point after sending the beacon, an Orthogonal Frequency Division Multiple Access (OFDMA) trigger to the station, wherein the OFDMA trigger causes the station in the power-save mode to send PS-POLL using OFDMA, receiving, by the access point and from the station, a PS-POLL frame using OFDMA.

Abstract: Examples described herein mitigate adjacent channel interference for dual radios of a network device. Examples described herein may associate, by a network device, a first client device with a first radio of the network device, associate, by the network device, a second client device with a second radio of the network device, determine that the first and second client devices are within a steering threshold, and based on the determination that the first and second client devices are within the steering threshold, steer, by the network device, the second client device from the second radio to the first radio. Examples described herein may communicate, using the first radio of the network device, with the first and second client devices.

Abstract: Example method includes: allocating, by a main processor of a wireless access point (WAP) comprising at least the main processor and a plurality of co-processors wherein the main processor and the plurality of co-processors both have access to a random-access memory (RAM) co-located within the WAP, a dedicated non-overlapping segment of the RAM to each of the plurality of the co-processors; receiving, by the main processor of the WAP, a notification from one of the plurality of co-processors indicating that an exception previously defined by the one of the plurality of co-processors has occurred; determining, by the main processor of the WAP, the dedicated non-overlapping segment of the RAM allocated to the one of the plurality of co-processors; and saving, by the main processor of the WAP, the dedicated non-overlapping segment of the RAM allocated to the one of the plurality of co-processors to a fast access memory.

Abstract: Systems and methods are provided for aggregating Media Access Control (MAC) Protocol Data Units (MPDUs) destined for different peers, and may have the same or different source address information, e.g., within the same or across different virtual access points (VAPs). For example, trigger frames used to signal to devices which subchannel(s) those devices can utilize, may be aggregated. For example, a multi-VAP/multi-device block acknowledgement for acknowledging packets transmitted to devices belonging to different VAPs can be sent as an aggregated MPDU.
