1. A method for a wireless communication device comprising a main receiver and a wake-up receiver (WUR) having a channel selective filter, the method comprising:
determining a correlation metric for the WUR, based on the following:
a signal received via the WUR using the channel selective filter configured according to a first one of a plurality of available bandwidths, and
a reference signal that is representative of a wake-up signal (WUS) transmitted by an access point node;
detecting a WUS included in the received signal, based on the correlation metric in relation to a first threshold; and
in response to detecting the WUS, selecting a second one of the plurality of available bandwidths for the channel selective filter, based on the correlation metric in relation to a second threshold different than the first threshold.
