description A method includes receiving a signal including a two-dimensional signal pattern in a time-frequency representation, wherein the two-dimensional signal pattern includes a first reference signal at a predetermined first position in the two-dimensional signal pattern and at least one second reference signal at a predetermined second position in the two-dimensional signal pattern. The first reference signal includes cell identification information of a target cell of a cellular radio system and the at least one second reference signal includes cell identification information of at least one interfering cell of the cellular radio system. The method further includes determining a first noise covariance measure based on the first reference signal, determining at least one second noise covariance measure based on the at least one second reference signal, and mitigating an interference included in the received signal based on the first noise covariance measure and the at least one second noise covariance measure.
