Abstract

A technique for cancelling inter-cell or intra-cell interference in a cellular communication network is described. A method implementation of that technique performed in an interfered terminal comprises receiving a signal, wherein the received signal comprises an interfering signal destined to at least one further terminal different from the interfered terminal. In a next step, control information pertaining to the at least one further terminal is determined and the interfering signal is decoded based on the control information so as to generate decoded information. Then, the interfering signal is re-generated from the decoded information and the control information. Based on the re-generated signal the interfering signal is cancelled from the received signal.
