Abstract: The present invention relates to a method and a transceiver device in a wireless communication system that enable tuning of the polarization generated by a cross- polarized transmitting antenna configuration of an eNB. This is addressed by a solution where the polarization is adjusted (320) based on a quality indicator e.g. received (310) from one or more UEs. The quality indicator indicates the quality of the communication between the eNB and the UEs, and is used to determine if the adjustment of the antenna configuration is improving the quality of the communication or not. The tuning is thus an iteration (330) of the steps of adjusting (320) the polarization and of receiving (310) the quality indicator, and when the quality indicator has reached a pre-determined value, the iteration is stopped.
