A wireless device, and a method therein, for performing a measurement on a first type of radio signal. The wireless device is comprised in a communications network. The wireless device receives at least two resource specific parameters for the first type of radio signal. The at least two resource specific parameters indicate different transmit power levels of the first type of radio signal and the different transmit power levels relate to two different resources in two different time periods for the first type of radio signal. Further, the wireless device receives a first type of radio signal transmitted at two different transmit power levels, and performs at least one measurement on the received first type of radio signal using the at least two resource specific parameters.
