The present invention provides a base stationfor receiving vehicle control information and/or traffic state information from a vehicle control unit, preferably connected to the base station. The base station comprises a base band unit, and at least one interface, wherein the base band unitis connected to the at least one interface, and wherein the at least one interfaceis configured to communicate with at least one application processing unitfor processing the vehicle control information and/or the traffic state information in the at least one application processing unit, and to receive a result of the processing from the at least one application processing unit. The base stationis further configured to forward the result of the processing to the vehicle control unit

Base station for receiving and processing vehicle control information and/or traffic state information

The disclosure relates to an antenna device, configured to assign antenna beams to radio cells, the antenna device comprising: a set of radio transceivers coupleable to a set of antenna ports of an antenna array, each radio transceiver being configured to drive a respective antenna port of the antenna array when each radio transceiver is coupled to the respective antenna port, wherein the set of radio transceivers is configured to drive the antenna ports to generate at least two antenna beams, wherein each radio transceiver contributes to the generation of each antenna beam.

Antenna device and method for driving antenna ports of an antenna array

The invention relates to a method for increasing the precision during the determination of system parameters dependent on the propagation delay, e.g. for a positional determination, in a mobile communications system with emission diversity, according to which a subscriber data signal and a reference signal are assigned to a subscriber. The subscriber data signal is emitted by at least two antenna devices on the emission side, whereas the reference signal is emitted exclusively by one antenna device on the emission side. The reference signal is used to precisely determine signal propagation delays, upon which the system parameters depend.

Positional determination of a user in a mobile communications system with emission diversity

The communications system operates at two distinct operating modes. Each of the slave stations, which are controlled by a master station, has a first output circuit and a second output circuit. The two output circuits are connected to one another on the output side. In a first operating mode, the slave stations are identified by the master station, all the first output circuits can be activated and the system operates at a low clock rate. In a second operating mode, a transfer of data takes place, one of the second output circuits can be activated, and the system operates at a higher clock rate.

Slave station with two output circuits commonly and directly connected to a line for serially transmitting data to a master station in two operational modes

The operation of any desired number of initially unidentified slave stations in a communications system is possible. An identification procedure with a subsequent address assignment is carried out by a master station M, in that all the slave stations simultaneously output bit by bit, via open-drain output circuits OC, individual identification codes ID which are stored in them.
