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

摘要： An objective problem of the invention is to provide a mechanism for improving the performance of a radio access network. According to a first aspect of the present invention, the object is achieved by a method in a first node for adapting a multi-antenna transmission to a second node over an effective channel. The first node and the second node are comprised in a wireless communication system. The method comprises the steps of obtaining at least one symbol stream and determining a precoding matrix having a block diagonal structure. The method comprises the further steps of precoding the at least one symbol stream with the determined precoding matrix, and transmitting the at least one precoded symbol stream over the effective channel to the second node.
