Abstract
A method in a wireless device (900) of transmitting uplink reference signals from the wireless device (900) in a wireless communication network (100) to enable network-centric measurements comprises obtaining power control information defining a time-dependent power control setting for said uplink reference signals. The method also comprises determining transmit power values for the uplink reference signals according to the time-dependent power control setting, to provide uplink reference signals of different transmit power values at different time instants. The method further comprises transmitting the uplink reference signals with the determined transmit power values according to the time-dependent power control setting.
