Abstract: A base station for a radio communications systems contains at least one carrier-related transceiver device and at least one central unit for controlling the base station. The transceiver device and the central unit each contain at least one interface device which are connected by at least one individual line in accordance with a point-to-point connection for transmitting traffic data. Therefore, point-to-point connections with individual lines for each transceiver device that do not need to satisfy the requirements of identical lengths are used instead of a bus structure. In this way, an essentially more cost-effective implementation of the transmission of traffic data between the central unit and transceiver device is possible because the data rate can also be increased in accordance with the length of the individual line. A logic bus structure is mapped onto physical point-to-point connections. Traffic data, o&m data and also synchronization data are transmitted using the bus structure.

Abstract: In a radio station for mobile communication systems, the reception branches of at least two antenna units having different polarization are monitored in order to acquire statements about the polarization direction of the incident wave. Corresponding to the polarization direction of the incident wave, an adaptive fashioning of the radiation characteristic ensues, this fashioning the polarization direction of the emitted wave according to the weighting of the reception signals of the reception branches for the same communication connection. The connection from a base station to a mobile station in a mobile communication system therefore can be improved with an inventive radio station.
