    Abstract: 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.

    Abstract: Systems, methods, and other embodiments associated with processing wireless signals. According to one embodiment, a wireless receiver includes at least one antenna configured to receive a wireless signal. The wireless signal comprises pilot symbols dispersed irregularly throughout a two-dimensional grid.

The wireless receiver includes a pattern logic including hardware configured to generate additional pilot symbols in the two-dimensional grid. The additional pilot symbols generated by the pattern logic along with the pilot symbols dispersed irregularly throughout the two-dimensional grid form a regular distribution of pilot symbols in the two-dimensional grid. The wireless receiver is configured to estimate the wireless channel at each point in the two-dimensional grid based on the regular distribution of pilot symbols in the two-dimensional grid.
