Procedures and mechanisms for narrowband multi-channel transmission for wake up radios
Abstract:
Procedures and mechanisms for narrowband multi-channel transmission for wakeup radio (WUR) operation are disclosed. A station (STA) operating in WUR mode may have its a primary connectivity radio (PCR) turned off and its WUR turned and operating according to previously negotiated WUR operating parameters. The STA may monitor, for WUR beacons and frames over a first WUR channel, and determine that the first WUR channel does not support reliable transmission based on no beacons being received within a first duration. The STA may turn off the WUR, and turn on the PCR to send a first short WUR frame including a wakeup reason, and receive a second short WUR frame with a WUR channel assignment. The STA may turn off the PCR, turn on the WUR, and monitor for WUR signals on a second WUR channel according to the WUR channel assignment and the previously negotiated WUR operating parameters.
