Abstract: Systems and techniques are described that are directed to filter frequency response shift compensation, including compensating for shifting in the rejection band of the filter. Compensation for the shifting in the rejection band can include applying a pre-distortion to attenuate edge resource units (RUs), and applying PHY Protocol Data Unit (PPDU) scheduling schemes. For example, a PPDU scheduling scheme reduce bandwidth in the channel, thereby dropping the out of band RUs. Front ends provide feedback to a respective radio, which allows that radio to apply the appropriate pre-distortion. The front ends can include one or more filters enabling frequency domain coexistence between collocated radios operating in the differing Wi-Fi bands, and a coupler that provides the feedback indicating the frequency response shift to a radio. The radio can then apply a digital pre-distortion to compensate for the shifting in the rejection band.

Abstract: Systems and methods are provided for determining, at a beamformee, to transmit data signals from transmitting spatial streams at one or more beamformers. Next, a gain resulting from an uplink transmit beamforming protocol may be determined to exceed an overhead of the transmit beamforming protocol. In response to the determination, the uplink transmit beamforming protocol may be conducted. This protocol includes, transmitting trigger frames to the beamformers to obtain channel data regarding channels between each of the transmitting antennae and the active receiving antennae, receiving responses to the trigger frames from each of the beamformers, generating the channel data based on the received responses, feeding back the channel data to each of the beamformers, scheduling the uplink transmit beamforming protocol based on the channel data, and receiving an integrated data signal from the beamformers based on a processing of the data signals via the uplink transmit beamforming protocol.

Abstract: Systems and methods are provided for synchronizing uplink (UL) and downlink (DL) traffic. In particular, frames associated with Quality of Service (QoS}-sensitive traffic flows to be transmitted in a first direction are prioritized commensurate with frames to be transmitted in a second direction, different/opposite to that of the first direction. For example, UL traffic flows can be prioritized based on DL traffic flows, where the traffic flows belong to the same application flow, and vice versa, where DL traffic flows can be prioritized based on UL traffic flows for the same application flow. In this way, end-to-end QoS can be achieved.

Abstract: Systems and methods are provided by which all APs in a particular deployment can be used to assist in the out-of-band discovery of 6 GHz radios by client devices. That is, a series of iterative operations can be performed to: (I) determine the state of 6 GHz radios in a zone/deployment area; (II) identify what radios can be considered near-neighbors to non-6 GHz radios for purposes of advertising one or more of the 6 GHz radios; (Ill) rank neighboring 6 GHz radios for a given non-6 GHz radio based on certain radio metrics; and (IV) ultimately determine those 6 GHz radios that can be advertised by the given non-6 GHz radio.

Abstract: An access point of a network configured to derive basic service set identifiers (BSSIDs). The access point determines a base media access control (MAC) address associated with an access point. The access point computes an offset for at least one radio of the access point. The access point determines a radio-specific MAC address for the at least one radio of the access point by incrementing the base MAC address by the offset. The access point then derives a plurality of BSSIDs for the at least one radio of the access point based on the radio-specific MAC address. In some cases, the access point determines a radio from which a BSSID is provided based on the BSSID.

Abstract: Systems and methods are provided for using a short data frame sent at a particular rate that can be used to probe a channel on which an access point is operating. The rate can be increased/decreased depending on whether or not transmission of the short data frame was successful or not. In this way, the highest possible rate (which can be impacted by any or all of the following factors: number of spatial streams, modulation and coding scheme, channel bandwidth, guard interval) can be selected to transmit data on the channel. In other words, a transmission rate can be selected dynamically and on a per-packet basis for a spatial reuse data frame that would follow the short data frame based on whether transmission of the short data frame was successful.

Abstract: Systems and methods are provided for transmitting buffer state report poll (BSRP) triggers from a WLAN device with a BSRP frequency that is based on an amount of pending data at the UL buffer of each station associated to the WLAN device. The BSRP frequency can further be based on a priority of the pending data at the UL buffer. The amount of pending data at the UL buffer can be compared to a threshold, the value of which can depend on the priority of the pending data, and the BSRP frequency can be based on the comparison.

Abstract: Systems and techniques are described that are directed to intelligent scheduling of Wi-Fi services for applications, including enhanced dynamic prioritization. A device, such as an access point (AP), can receive data packets from multiple connected devices to dynamically identify an application flow for each data packet, and dynamically identify a user associated with the application flow for each data packet. The AP can generate prioritized candidate lists for selected data packets in queues corresponding to an access category (AC). In response to determining that the identified user associated with the application flow corresponds with a critical user, the AP can select data packets for the prioritized candidate lists based at least in part on priority policies for each of a plurality of applications and based at least in part on dynamic prioritization of applications for each of a plurality of applications; and schedule data packets from the prioritized candidate lists.
