According to the present invention, a user equipment (UE) receives a beam-formed paging message based on a feedback, which is transmitted by the UE to a network. The UE receives, in a first period, a paging indicator via multiple beams from a network node, and selects a beam from the multiple beams. Then, the UE transmits, in a second period, a feedback indicating the selected beam to the network node via the selected beam, and monitors, in a third period, the selected beam to acquire a paging message from the network node.
