Abstract

Apparatus in a wireless telecommunications system comprises at least a first antenna of a first polarization and a second antenna of a second polarization. The apparatus additionally comprises a receiver and a transmitter, and is intended for communication with at least one other device in the wireless telecommunications system. The apparatus is equipped with a polarization estimator for estimating the polarization state of a signal which is received from the one other device, and a polarization controller for adapting the polarization state of signals transmitted from the apparatus to the one other device on the basis of the estimate of the received signal.
