Abstract:
An access point (AP) that supports the IEEE 802.11ba protocol may transmit a frame including a physical layer (PHY) preamble to one or more stations (STAs) over a channel. The PHY preamble may include a plurality of repeated modulated legacy signal (L-SIG) fields to spoof a recipient of the frame and protect a wake up signal (WUS) to be subsequently transmitted by the AP. The AP may transmit the WUS to at least a first STA of the one or more STAs, wherein the at least the first STA is a IEEE 802.11ba compliant STA.
