Information about a set of cells potentially taking part in coordinated multipoint transmission (COMP) is obtained by a UE(S21). Information about at least one of reference signal configuration and data region size configuration for each of the set of cells is obtained (S22). An indication of which of the reference signals configuration and the data region size configuration should be assumed in resource mapping for data is obtained (S23), and data according to the resource mapping is received (S24) by the UE. In S22, the UE may detect PCFICH to get the PDCCH region size. Alternatively the UE is signaled the PDSCH starting position for the CSI-RS resource corresponding to the serving cell. In S23 the UE receives the downlink grant containing the proposed control information field. |
