    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: 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 described for prioritizing channel access to uplink (UL) multi-user (MU) data capable active stations (STAs) by dynamically adapting a MU enhanced distributed channel access (EDCA) parameter set to provide for increased access to the channel by the UL MU data capable active STAs when the total number of active STAs associated to the AP less the number of active UL MU capable STAs exceeds the number of active UL MU data capable STAs; and by dynamically adapting the MU EDCA parameter set to equal a legacy EDCA parameter set to reduce collisions between the UL MU data capable STAs when the number of active UL MU data capable STAs exceeds or equals the total number of active STAs associated to the AP less the number of active UL MU data capable STAs.

    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.

    Abstract: Currently, spatial reuse (SR) is a feature used indiscriminately for/across all traffic classes. However, systems and methods are provided for increasing the reliability of voice traffic and Transmission Control Protocol (TCP) Acknowledgement (ACK) messaging. The result is improved quality of voice calls, and enhanced network capacity. When the length of a data section of a packet suggests that subsequent packets are associated with voice traffic or TCP ACKs, such packets are not transmitted when another transmission(s) is occurring under spatial reuse. When a determination is made that the length of a data section of the packet suggests non-voice traffic or TCP ACKs, they can be transmitted simultaneously with other transmissions occurring under spatial reuse.
