Procedures and mechanisms for narrowband multi-channel transmission for wake up radios

A method performed by a station (STA), the method comprising:

• sending, 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, and WUR channel information recommending a WUR channel for the STA;
• receiving, 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
• switching to a WUR operating mode and monitoring 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.

An access point (AP) comprising:

• a transceiver;
• and
• a processor, wherein the transceiver and the processor are configured to:
• receive, from a station (STA), a first wakeup radio (WUR) frame including an indication of a request to enter WUR mode, and WUR channel information recommending a WUR channel for the STA;
• send, to the STA, in response to reception of 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
• send WUR signals, to the STA, on a first WUR channel in accordance with the indicated first WUR channel assignment and the indicated WUR beacon interval.
