  • Patent number: 10779236
    Abstract: Embodiments of an AP and wake up radio (WUR) non-AP station (STA) are generally described herein. The AP may transmit a WUR packet to wake up a wireless local area network (WLAN) radio of the WUR non-AP STA. A non-WUR portion of the WUR packet may include legacy fields and a BPSK mark to spoof high throughput (HT) devices receiving the WUR packet. The AP may transmit the BPSK mark in a channel that includes a lower guard band, a transmission bandwidth, and an upper guard band. The AP may encode the BPSK mark in accordance with: on-off keying (OOK) modulation in a center portion of the transmission bandwidth; and orthogonal frequency division multiplexing (OFDM) in a remaining portion of the transmission bandwidth that excludes the center portion.

  • Publication number: 20200267636
    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.
