Abstract
A technique for measuring Reference Signal Received Power (RSRP) is provided. The RSRP is measured based on Cell-specific Reference Signals (CRSs) provided by cells () of a mobile telecommunications network (). The CRSs of at least two of the cells overlap in time and frequency. As to a method aspect of the technique, a time offset for sub-frames received from the at least two cells is determined. The overlapping CRSs are received for a group of sub-carriers. A coarse channel state is estimated for each of the at least two cells by multiplying the received overlapping CRSs with a function of phase-shifted CRSs. The phase-shifted CRSs of different sub-carriers in the group include a phase-shift that corresponds to the determined time offset. The RSRP is measured for each of the at least two cells based on the estimated coarse channel state.
