CALIBRATION METHOD AND DEVICE IN TELECOMMUNICATION SYSTEM

摘要

A device [10, 12] system, computer medium and method for calibrating at least one impairment of a signal transmitted from a transmitting unit [10] to a receiving unit [12], the method including receiving at the receiving unit [12] at least two signals [14, 16] transmitted from the transmitting unit [10], estimating at the receiving unit [12], based on the received at least two signals [14, 16], at least one parameter associated with transmit chain links [20, 22] between the transmitting unit [10] and corresponding antennas [18] of the transmitting unit [10], collecting the at least one parameter in a measurement report at the receiving unit [12], and transmitting the measurement report from the receiving unit [12] for correcting the at least one impairment based on the at least one parameter.
