1. A method in a wireless communication terminal, the method comprising:
- receiving, at the wireless communication terminal, a subframe that belongs to a first subset of subframes, the subframe including a desired signal from a first base station and an interference signal,wherein the interference signal includes a cell-specific reference signal transmitted by a second base station;
receiving, at the wireless communication terminal, assistance information from the first base station, the assistance information including a number of cell-specific reference signal antenna ports configured in the second base station;
determining a structure associated with the cell-specific reference signal based on the assistance information;
reducing interference from the cell-specific reference signal on the received subframe based on the determined structure of the cell-specific reference signal; and
recovering the desired signal.

Abstract
A method in a wireless communication terminal is disclosed. The method includes receiving a first signal including a desired second signal and an interference component, wherein the interference component includes at least a third signal transmitted in an Almost Blank Subframe (ABS) by a neighbor cell, and configuring the wireless communication terminal to employ interference reduction to process the first signal based on a configuration of the interference component.
