A method for use in a wireless transmit/receive unit (WTRU) is disclosed. The method comprises: generating, by a Station Management Entity (SME), a request primitive enabling a wake-up radio (WUR) scanning process for WUR discovery frames transmitted by one or more access points (APs), the request primitive comprising a plurality of first parameters; conducting the WUR scanning process using WUR based on the plurality of the first parameters; generating, at a MAC layer, at least one confirm primitive based on a result of the WUR scanning process and at least a part of the plurality of first parameters; and communicating, from the MAC layer to the SME, the at least one confirm primitive.
