A method includes receiving in a mobile communication terminal signals from a group of cells that cooperate in a Coordinated Multipoint (CoMP) transmission scheme. Signaling information is received from a first cell in the group. The signaling information is indicative of a first pattern of time-frequency Resource Elements (REs) used by the first cell for transmitting reference signals, and is further indicative of a second pattern of the REs used by a second cell in the group for transmitting the reference signals. A third pattern of the REs, which are available for receiving data from the cells, is derived in the terminal from the signaling information that is indicative of the first and second patterns. The data from the cells is received in the terminal in one or more of the REs in the third pattern.
