Abstract
Systems and methods for wake up signaling in 802.11 DFS channels include enabling a primary connectivity radio of a device responsive to a wake up radio of the device receiving a composite radio signal transmitted by an access point in an 802.11 Dynamic Frequency Selection (DFS) channel, the composite radio signal comprising a wake up radio signal and a time-continuous signal, the time-continuous signal being substantially adjacent in frequency, but not necessarily contiguous in frequency, to the wake up radio signal; and exchanging data with the access point through the primary connectivity radio after the primary connectivity radio is enabled. The wake up radio signal may be an IEEE 802.11ba signal disposed in a center frequency band of a IEEE 802.11ax Physical Layer Convergence Protocol (PLCP) Protocol Data Unit (PPDU). The time-continuous signal may be real or emulated data traffic disposed in at least one IEEE 802.11ax resource unit.
