摘要： A method includes, in a mobile communication terminal, receiving signals from a group of cells in multiple time-frequency Resource Elements (REs). The signals include a desired signal component and an interfering signal component. A subset of the REs, in which the cells are known deterministically to transmit at least part of the interfering signal component and to not transmit the desired signal component, is identified in the terminal. An interference caused by the interfering signal component to the desired signal component is estimated in the terminal, by measuring the signals in the REs in the subset.
