1. A station (STA), the STA comprising:
a transceiver; and
a processor, wherein the transceiver and the processor are configured to:
send in a main radio operating mode, to an access point (AP), a first wakeup radio (WUR) frame including an indication of a request to enter WUR mode, WUR duty cycle information, WUR channel information recommending a WUR channel for the STA, and WUR data rate information;
receive in the main radio operating mode, from the AP, in response to the first WUR frame, a second WUR frame including an indication of a first WUR channel assignment and an indication of a WUR beacon interval; and
switch to a WUR operating mode and monitor a wireless medium for WUR signals, from the AP, on a first WUR channel in accordance with the indicated first WUR channel assignment and the indicated WUR beacon interval.
