1. A method in a first base station serving a first cell having a first coverage area at least partly overlapping with a second coverage area of a second cell served by a second base station, the first base station operating within a first transmission power range and the second base station operating within a second transmission power range, the first transmission power range having transmission power levels being higher than transmission power levels of the second transmission power range, the method comprising the steps of:

  • determining radio link quality of a user equipment (UE1) connected to the first base station and being located in an adjustable extended coverage range of the second base station,requesting from the second base station, interference related measurements for unused physical channels or for physical channels at least partially overlapping with physical channels used by the user equipment (UE1) connected to the first base station and having the radio link quality falling below a threshold value thus indicating poor radio link quality to the first base station, anddeciding for the user equipment (UE1) connected to the first base station, based on the interference related measurements, whether a handover to the second base station should be performed.
