Title: METHOD AND ACCESS NODE FOR SUPPORTING UE AS WELL AS A UE AND CORRESPONDING METHOD CARRIED OUT BY THE UE IN A WIRELESS COMMUNICATION SYSTEM
Abstract:
The present invention relates to a method and access node for supporting one or more UEs as well as to a method carried out by a UE and the UE itself which enable to use resource and energy efficiently. The method for supporting one or more user equipments, UEs, in a wireless communication system, comprises transmitting from an access node a first reference signal in a beam; determining whether the access node received at least one indication about a UE's presence in the coverage area of the beam; and switching from transmitting of the first reference signal to transmitting a second reference signal if the access node received at least one indication about a UE's presence in the coverage area of the beam.
