Summary:Embodiments include methods for a wireless communication device comprising a main receiver and a wake-up receiver (WUR) having a channel selective filter. Such methods include 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. Such methods include 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 available bandwidths for the channel selective filter, based on the correlation metric in relation to a second threshold. Other embodiments include complementary methods for an access point node, as well as apparatus configured to perform such methods.
