Performing Duty Cycled Listening In a Receiver
23 Nov 23
In one aspect, a method includes: enabling, via a controller of a network device, a receiver of the network device for a plurality of receive fragments during a receive duration; analyzing a signal fragment received during at least one of the plurality of receive fragments to identify possible presence of a wake-up frame sent by a coordinator device; and in response to the identification of the possible presence of the wake-up frame, enabling the receiver to receive and detect another wake-up frame.
