Abstract
The present invention relates to a method for controlling performance in a radio base station communicating in a Time Division Duplex (TDD) mode in a cellular network. The radio base station has a transceiver comprising a transmitter part, a receiver part, and an antenna, the antenna being alternately connectable to the transmitter part and the receiver part. The method comprises: estimating, at the receiver part, a leakage signal in the receiver part, the leakage signal originating from a local oscillator of the transmitter part; and removing, at the receiver part, the estimated leakage signal from a received uplink signal. The present invention also relates to a corresponding radio base station.
