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 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.

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: 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 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: Currently, spatial reuse (SR) is a feature used indiscriminately for/across all traffic classes. However, systems and methods are provided for reducing channel access latency via selective application of SR for latency-sensitive and high-priority traffic. If a radio frequency (RF) signal is detected on a channel used by an access point (AP) or a client device, a determination can be made as to whether the energy of the RF signal relative to SR energy level thresholds permits transmission on that channel used simultaneously by another, e.g., neighboring AP. If so, frames can be transmitted so long as the other neighboring AP is associated with a different basic service set (BSS) color than that of the AP, and so long as the frames to be transmitted belong to a high-priority/low-latency traffic access category.

Abstract: Systems and techniques are described that are directed to filter frequency response shift compensation, including attenuation compensation. Attenuation compensation can apply a pre-distortion to compensate for the magnitude of attenuated resource units (RUs). Additionally, filter frequency response shift can involve applying PHY Protocol Data Unit (PPDU) scheduling schemes. For example, a PPDU scheduling scheme can reduce bandwidth in the channel, thereby dropping the affected RUs. The attenuation compensation is implemented using front ends that provide feedback to a respective radio, which allows that radio to apply the appropriate pre-distortion. The front end 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 then applying a digital pre-distortion to a signal input into the one or more filters to compensate for the attenuated RUs.
