摘要： A method is disclosed for use in a heterogeneous telecommunications system of the kind comprising a macro base station and a low-power base station, the low-power base station having a coverage which is extendible by range expansion, RE, to serve a user equipment which would otherwise have been served by the macro base station. According to the method, which is performed in either of the macro base station or the low-power base station, information about radio conditions of the user equipment at least with respect to the macro base station is obtained (310). Based on the obtained information, it is determined (320) whether a criterion for conditional range expansion is satisfied, said criterion being related to the uplink transmission power of the user equipment to the macro base station. Accordingly, range expansion is applied (330) for the user equipment only when the criterion is satisfied. A corresponding base station, telecommunications system and computer readable storage medium are also disclosed.
