Abstract:
1. A method in a first base station for calculating a first location parameter (α) of a user equipment in order to improve beamforming accuracy within a Coordinated Multiple Point (CoMP) communication system, which communication system comprises the first base station, the user equipment and a second base station, the method comprising: measuring a signal received from the user equipment; determining a first estimate (α′) of the first location parameter, based on the measured signal; obtaining a second estimate (α″) of the first location parameter, based on a second location parameter of the user equipment, estimated at the second base station, said second location parameter is different from said second estimate of the first location parameter; calculating the first location parameter based on the first estimate of the first location parameter and the obtained second estimate of the first location parameter.
