  • Publication number: 20200305006
    Abstract: An access point (AP) station (STA) (AP STA) may be configured to operate as a multi-AP controller in a multi-AP network. A multi-AP group formation message is encoded for transmission to other APs in the multi-AP network. The multi-AP group formation message is encoded to notify the APs of the formation of an extremely-high throughput (EHT) multi-AP group, to designate whether an AP is a member of an EHT multi-AP group, and whether an AP can take the role of a coordinator AP or coordinated AP within the EHT multi-AP group. For multi-AP joint processing, the AP STA is further configured to encode an AP trigger frame for transmission to the APs in the multi-AP network. The AP trigger frame is to trigger physical layer (PHY) and medium-access control layer (MAC) parameter synchronization. The AP trigger frame is to trigger transmission of aggregated MAC protocol data units (A-MPDUs) by the APs that include MAC parameters and PHY parameters.

  • Publication number: 20200296669
    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.

  • Patent number: 10728856
    Abstract: Logic may implement protocols and procedures to suspend a wake-up radio mode. Logic may enter a wake-up radio (WUR) mode suspend with a WUR request indicative of the WUR mode suspend. Logic may enter the WUR mode suspend from a WUR mode with a one-way handshake and may exit from the WUR mode to the WUR mode suspend. Logic may negotiate WUR mode parameters without entering the WUR mode. Logic may default to a WUR mode or a WUR mode suspend in response to receipt of a wake-up packet. Logic may receive the WUR request frame with a WUR mode suspend field to request entry into a WUR mode suspend. Furthermore, logic may maintain negotiated WUR mode parameters during the WUR mode suspend.
