Claim:
1. A method, comprising: receiving a signal comprising a two-dimensional signal pattern in a time-frequency representation, wherein the two-dimensional signal pattern comprises 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, wherein the first reference signal comprises cell identification information of a target cell of a cellular radio system and the at least one second reference signal comprises cell identification information of at least one interfering cell of the cellular radio system; further wherein a position of a first part of the at least one second reference signal is spaced apart by a predetermined frequency shift from a position of a first part of the first reference signal, wherein the predetermined frequency shift corresponds to an interfering cell; mitigating interference in the cellular radio system by:
