Abstract:
The invention relates to a method 10 performed in a user equipment 3, 4 of a communication system 1 for determining a beam-forming gain parameter, the communication system 1 comprising a base station 2 serving the user equipment 3, 4. The method 10 comprises: receiving 1 a cell-specific reference signal and a dedicated reference signal from the base station 2; measuring 12 a received power, PRSRP, of the cell-specific reference signal and a received power, PDRSRP, of the dedicated reference signal; and determining 13 a beam-forming gain parameter, GBF, based on the measured received power, PRSRP, of the cell-specific reference signal and on the measured received power, PDRSRP, of the dedicated reference signal. The invention also relates to user equipment, methods in base station, base station, computer programs and computer program products.
