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: Systems and methods are provided for defining a split multi-link system. For example, the split multi-link system can define a multi-link device (MLD), where the MLD operates a first radio from a first AP of a plurality of APs and a second radio from a second AP of the plurality of APs through a Media Access Control (MAC) Service Access Point (SAP) of the split multi-link system. The first radio from the first AP and the second radio from the second AP may operate at different frequencies. The split multi-link system may also affiliate the first radio from the first AP and the second radio from the second AP with the MLD, where, using the MLD, the split multi-link system can transmit or receive one or more data frames from the MLD to a non-MLD or MLD client device using the first radio or the second radio.

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: 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: Embodiments are directed to dynamic frequency selection (DFS) for wake up radio (WUR). An embodiment of a storage medium includes instructions to cause operations including select, by a primary access point (AP), a surrogate AP to communicate with a wake up radio of a station that is associated with the primary AP operating on a Dynamic Frequency Selection (DFS) channel; provide, by the primary AP to the surrogate AP, wake up radio parameters negotiated between the station and the primary AP; cause, by the primary AP, the surrogate AP to send a wake up signal to the station, the wake up signal to cause the wake up radio of the station to enable a primary connectivity radio of the station; and exchange, by the primary AP, data with the station via the primary connectivity radio after the primary connectivity radio is enabled.

Abstract: Systems and methods for assigning default an alternative BSS colors in a wireless local area network (WLAN) including a network graph representing radio neighbors include assigning a frequency range and EIRP for each radio represented in the network graph; generating a subgraph of radios operating at the same frequency range; for the subgraph, determining a minimum number of basic service set (BSS) colors required to BSS color the subgraph without BSS color conflict; based on the minimum number of BSS colors, assigning a default BSS color to each radio in the subgraph to avoid BSS color conflict among radios in the subgraph; based on remaining BSS colors, assigning one or more alternative BSS colors to each radio in the subgraph.
