Abstract
A method and controlling node (400) of a cellular network, to control measurements on signals to or from a User Equipment, UE, engaged in a radio communication in a cluster cell served by multiple transmission points (404). A set of conditions potentially affecting performance for the UE in the cluster cell, is identified. At least one type of reference signals and corresponding radio measurement(s) are then selected based on the identified set of conditions. The controlling node obtains measurements made on the selected type(s) of reference signals according to the radio measurement(s), and configures a UE-specific measurement set of transmission points (406) for the UE, out of the transmission points (404) serving the cluster cell, based on the obtained measurements. The UE is then instructed to perform and report measurements on UE-specific downlink signals transmitted from the transmission points of the UE-specific measurement set.
