Abstract: A method of operating a user equipment for measuring non-contiguous carriers comprises: changing a position of a local oscillator to be in the middle of the non-contiguous carriers; measuring the carriers simultaneously; estimating a power level of an interferer in a gap in the non-contiguous carriers which creates image interference; and compensating the measurement dependent on the interferer power level and an image rejection factor.

Abstract: A method of setting a Radiofrequency, RF, signal level in a RF receiver comprising: estimating an error of the signal level due to signal level reaching a condition of jamming or clipping by correlating the signal level with a point of a characterization curve of jamming condition or with a point of a characterization curve of clipping condition (300), respectively; correcting the RF signal level based on the error; and, wherein: each of the characterization curves comprises a plurality of points comprising first points determined in a previously performed characterization at a point of measurement and groups of second points stepped between pairs of adjacent first points, said plurality of first points including at least three points defining at least two sections of the characterization curve.
