  • Patent number: 11336487
    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.

  • Publication number: 20220110099
    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.

  • Publication number: 20220110052
    Abstract: The full efficiency gains of the Target Wake Time (TWT) mechanism specified in the 802.11ax standard may not be realized when stations associated to an access point (AP) are spread across multiple Base Station Service Identifiers (BSSIDs). In such a scenario, TWT as conventionally utilized/specified in the 802.11ax standard, cannot properly coordinate sleep/wake schedules for stations due to associating to different BSSIDs. Accordingly, various embodiments are directed to grouping stations associated to multiple BSSIDs of an AP to allow for the synchronization (or staggering) of TWT, and facilitate multi-user transmissions, both in the uplink and downlink directions.

  • Publication number: 20210068014
    Abstract: Techniques and mechanisms for offloading of off-channel scanning. Characteristics corresponding to wireless client devices within a wireless network are evaluated. A request is sent from a wireless access point of the wireless network to one or more selected wireless client devices from wireless client devices. The request causes the one or more selected wireless clients to perform off-channel scanning. Reports are received from the one or more selected wireless client devices having information gathered by the off-channel scanning performed by the selected wireless client devices. Information from the reports is utilized to perform network setting modification.
