A method performed by a user equipment, UE, in an idle mode for handling inter-frequency cell reselection in a wireless communications network, which UE is camped on a first cell of a radio base station, said first cell having a first frequency, wherein the first frequency has a higher priority than other frequencies, wherein said wireless communications network comprises a second cell having a second frequency, said second cell having at least partly overlapping coverage with said first cell, and a third cell having said second frequency, said third cell having at least partly overlapping coverage with said first cell; said method comprising: receiving cell reselection priority values from said radio base station, wherein said cell reselection priority values are transmitted via system information and/or in a dedicated Radio resource Control, RRC, message, wherein said cell reselection priority values comprise a first cell reselection priority value for said second cell, and a second cell reselection priority value for said third cell, wherein said first cell reselection priority value and said second cell reselection priority value are different, and performing Reference Symbol Received Power, RSRP, measurements on the cell (132, 133) having the highest cell reselection priority value according to the cell reselection priority values received, provided the highest cell reselection priority value is higher than the priority of the first frequency; and reselecting to the second cell or the third cell, if: the RSRP measured on the second or third cell is above a cell reselection threshold, Thresh X,HighP· wherein said wireless communications network comprises a second cell having a second frequency, said second cell having at least partly overlapping coverage with said first cell, and a third cell having said second frequency, said third cell having at least partly overlapping coverage with said first cell; said method comprising: receiving cell reselection priority values from said radio base station, wherein said cell reselection priority values are transmitted via system information and/or in a dedicated Radio resource Control, RRC, message, wherein said cell reselection priority values comprise a first cell reselection priority value for said second cell, and a second cell reselection priority value for said third cell, wherein said first cell reselection priority value and said second cell reselection priority value are different, and performing Reference Symbol Received Power, RSRP, measurements on the cell (132, 133) having the highest cell reselection priority value according to the cell reselection priority values received, provided the highest cell reselection priority value is higher than the priority of the first frequency; and reselecting to the second cell or the third cell, if: the RSRP measured on the second or third cell is above a cell reselection threshold, Thresh X,HighP· receiving cell reselection priority values from said radio base station, wherein said cell reselection priority values are transmitted via system information and/or in a dedicated Radio resource Control, RRC, message, wherein said cell reselection priority values comprise a first cell reselection priority value for said second cell, and a second cell reselection priority value for said third cell, wherein said first cell reselection priority value and said second cell reselection priority value are different, and performing Reference Symbol Received Power, RSRP, measurements on the cell (132, 133) having the highest cell reselection priority value according to the cell reselection priority values received, provided the highest cell reselection priority value is higher than the priority of the first frequency; and reselecting to the second cell or the third cell, if: the RSRP measured on the second or third cell is above a cell reselection threshold, Thresh X,HighP·
