Abstract
A method for obtaining uplink calibration values in a terminal of a wireless communication system is provided, in order to enable a Base Station (BS) having a number of antennas to determine a respective hardware chain value for each antenna of the number of antennas, said method comprising calculating, by the terminal, an uplink calibration value for each antenna on the basis of a downlink channel estimate value for each antenna and a normalization value obtained from said downlink channel estimate values, and sending transmitting, by the terminal, the calculated uplink calibration value for each antenna to the BS. A corresponding terminal for a wireless communication system, adapted to obtain uplink calibration values, is also provided.
