  • Publication number: 20230061407
    Abstract: An access point station (AP) configured for wideband channel operation may communicate with non-access point stations (STAs) over channel bandwidths that include one or more primary channels. For channel bandwidths that include more than one primary channel, the AP may communicate with the STAs within those channel bandwidths even though the NAV of one of the primary channels within the channel bandwidth has not expired. In these embodiments, the AP does not need to wait for the NAV of a primary channel to expire to transmit a wideband transmission when another primary channel is the channel bandwidth is available.

  • Publication number: 20230028874
    Abstract: Embodiments disclosed herein are directed to communicating time-critical ultra-low latency (ULL) data using one or more dedicated resource units (RUs). A station (STA) decodes a trigger frame received from an access point station (AP) encoded to indicate resource units (RUs) of an UL PPDU for an uplink multi-user orthogonal frequency division multiple access (UL MU OFDMA) data transmission by a first and a second station STA. The trigger frame may also be encoded to indicate configuration information for a dedicated RU for time-critical ultra-low latency (ULL) UL data. The dedicated RU may be one RU of one or more RUs of the UL PPDU that are reserved for time-critical communications. The STA may encode time-critical ULL UL data for transmission to the AP on the dedicated RU during the uplink MU OFDMA data transmission by the first and second STAs. The time-critical ULL UL data may start at any time during transmission of the UL PPDU.

  • Publication number: 20220416964
    Abstract: Embodiments disclosed herein are directed to communicating time-critical ultra-low latency (ULL) data. An access point station (AP) communicates time-critical ULL data using aggregated MAC Protocol Data Unit (A-MPDU) preemption. When time-critical ULL data for a second associated STA (STA2) becomes available at a medium access control (MAC) layer of the AP during transmission of a physical layer protocol data unit (PPDU) to a first associate station (STA1), the AP may encode the time-critical ULL data in a new A-MPDU subframe for insertion before one of the A-MPDU subframes of the PPDU that has not yet been transmitted. The new A-MPDU subframe may be encoded to include zero-padding to set a size of the new A-MPDU subframe equal to a size of the A-MPDU subframe that has been preempted. The A-MPDU subframes 606 for STA1 may be encoded include a MAC address of the STA1 and the new A-MPDU subframe 608 may be encoded include a MAC address of the STA2.

  • Publication number: 20220400503
    Abstract: An access point station (AP) communicates with a plurality of non-AP stations (STAs) within a synchronized transmission opportunity (S-TXOP). The S-TXOP may comprise an S-TXOP trigger followed by a plurality of S-TXOP slots. The S-TXOP slots may be configured for communication of synchronous data. For communication of small time-critical (TC) packets within the S-TXOP with one or more of the STAs, the AP may configure the S-TXOP for asynchronous ultra-low latency (ULL) transmissions by providing a low-latency channel access opportunity within the S-TXOP.

  • Patent number: 11516757
    Abstract: Systems, methods, and devices related to an EHT multi-AP group are described. The coordinated APs of the EHT group are synchronized to the coordinator AP using a periodic or non-periodic frame. Each coordinated AP then synchronizes STAs associated with the coordinated AP. In response to an MPDU, either triggered by a trigger frame from the coordinator AP or initiated by the STA, an ACK frame or NDP response is sent by each AP receiving the MPDU. The response to the MPDU is dependent on whether frame aggregation is used, as well as whether the trigger frame triggers transmission of MPDUs from multiple STAs.

  • Publication number: 20220286947
    Abstract: An access point (AP) may be configured by processing circuitry to operate as a coordinator AP for performing BSS channel level coordination. The coordinator AP is configured to assign non-overlapping channels to one or more coordinated APs of overlapping BSSs to schedule time-sensitive traffic to help ensure bounded latency, jitter and reliability per BSS. In some embodiments, the AP may be configured for performing transmission level coordination and may initiate a coordinated transmission opportunity (TXOP) for resource assignment to control contention access among managed BSSs. To perform the BSS channel level coordination, the coordinator AP is configured to encode a multi-AP trigger frame (M-TF) to initiate the coordinated TXOP. The M-TF may be encoded to include a time-sensitive operation IE indicating how each STA is to access the channel within the coordinated TXOP.
