Apparatus and methods to support power saving in a wireless communication network and more particularly to support discontinuous reception of a wake-up signal receiver at an apparatus comprising a wake-up signal receiver and a main radio receiver are outlined. One aspect provides an apparatus comprising a wake-up signal receiver; a main radio receiver; means for determining that the wake-up signal receiver is a candidate to implement discontinuous reception; means for assessing a signal received by the apparatus from a transmitting network node; and means for requesting, based upon the assessment of the signal received, transmission of a timing synchronisation beacon to support implementation of discontinuous reception by the wake-up signal receiver from at least one transmitting network node. Requesting a beacon allows a transmitting network to assess whether use of power and radio resource to support such a beacon is appropriate.
