The present invention relates to a method in a RN node of a communications system operating on multiple carrier frequencies. The RN node hosts a first cell operating on a first carrier frequency and a second cell overlapping with the first cell and operating on a second carrier frequency. The method comprises broadcasting (501) information comprising a cell reselection priority for each of the first and the second carrier frequency in the first cell, where the priority of the first carrier frequency is the highest. The method also comprises broadcasting (502) information comprising a cell reselection priority for each of the first and the second carrier frequency in the second cell, where the cell reselection priority of the second carrier frequency is the highest. Thereby a UE will primarily perform intra-frequency cell reselection.
