description A method and controlling node (500) to control a signal combining operation performed on uplink radio signals transmitted from a User Equipment, UE, in a combined cell served by multiple radio nodes (502). Signal quality information (SQ) is received from the UE indicating a signal quality measured by the UE on a node-specific probing pilot signal (PS1-PS4) transmitted from each of the multiple radio nodes, and a subset (RN2-RN3) of the multiple radio nodes is selected based on the received channel quality information. The signal combining operation is then performing (204) on the uplink radio signals received by the selected subset of the multiple radio nodes. Thereby, the performance of the signal combining operation can be improved.
