Abstract

A transceiver for a vehicle for communication in a mobile radio system includes one or more interfaces for a plurality of antennas, and a transceiving device configured to communicate via the one or more interfaces and via at least a part of the plurality of antennas in the mobile radio system. The transceiver also includes a control device configured to control the transceiving device and the one or more interfaces, where the control device determines, via a first cluster of the plurality of antennas, information about a radio channel between the first cluster of antennas and a base station of the mobile radio system, and communicates via a second cluster of the plurality of antennas with the base station of the mobile radio system.

Claims

1. A transceiver for a vehicle for communication in a mobile radio system, comprising:

one or more interfaces for a plurality of antennas;

a transceiving device configured to communicate via the one or more interfaces and via at least a part of the plurality of antennas in the mobile radio system; and

a control device configured to control the transceiving device and the one or more interfaces,

wherein the control device is configured to determine, via a first cluster of the plurality of antennas, information about a radio channel between the first cluster of antennas and a base station of the mobile radio system and to communicate via a second cluster of the plurality of antennas with the base station of the mobile radio system.

2. The transceiver as claimed in claim 1, wherein the plurality of antennas comprises antennas having at least one of different orientations, different polarizations, different mounting locations on the vehicle, different antenna gains and different radiation characteristics,

wherein the plurality of antennas corresponds to an antenna system having at least one of decentralized and distributed antennas.

3. The transceiver as claimed in claim 1, wherein the information about the radio channel comprises information about at least one direction of incidence of radio signals.

4. The transceiver as claimed in claim 1, wherein the control device is configured to determine, using the information about the radio channel between the first cluster of the antennas and the base station of the mobile radio system, information about a radio channel between the second cluster of the antennas and the base station of the mobile radio system.

5. The transceiver as claimed in claim 4, wherein the control device is configured to determine the information about the radio channel between the second cluster of the antennas and the base station of the mobile radio system based on at least one of a speed, availability information about the mobile radio system, and a direction of travel of the vehicle.

6. The transceiver as claimed in claim 5, wherein the control device is configured to determine, via the one or more interfaces, information about the at least one of the speed, availability information about the mobile radio system, and the direction of travel of the vehicle.

7. The transceiver as claimed in claim 4, wherein the control device is configured to determine the information about the radio channel between the second cluster of the antennas and the base station of the mobile radio system based on at least one of (i) an assumption that at least one antenna of the first cluster of antennas is arranged in a direction of travel of the vehicle in front of at least one antenna of the second cluster, and (ii) an assumption that an antenna of the second cluster of antennas experiences the same radio channel as an antenna of the first cluster delayed in time.

8. The transceiver as claimed in claim 1, wherein the control device is configured to adaptively match a selection of antennas from the plurality of antennas for the first and the second cluster of antennas.

9. The transceiver as claimed in claim 7, wherein the control device is configured to select the first cluster of antennas based on a direction of travel of the vehicle such that at least one antenna of the first cluster is arranged in front of at least one antenna of the second cluster in the direction of travel of the vehicle.

10. The transceiver as claimed in claim 1, wherein the control device is configured to adaptively match a number of antennas in at least one of the first cluster and in the second cluster of antennas.

11. The transceiver as claimed in claim 1, wherein the transceiving device comprises two or more transceiving modules coupled to the plurality of antennas.

12. The transceiver as claimed in claim 1, wherein the control device is configured to perform beam forming with respect to the base station of the mobile radio system via the antennas in the second cluster.

13. The transceiver as claimed in claim 12, wherein the control device is configured to adaptively match a beam forming via the antennas in the second cluster.

14. A vehicle having a transceiver, wherein the transceiver comprises:

one or more interfaces for a plurality of antennas;

a transceiving device configured to communicate via the one or more interfaces and via at least a part of the plurality of antennas in the mobile radio system; and

a control device configured to control the transceiving device and the one or more interfaces,

wherein the control device is configured to determine, via a first cluster of the plurality of antennas, information about a radio channel between the first cluster of antennas and a base station of the mobile radio system and to communicate via a second cluster of the plurality of antennas with the base station of the mobile radio system.

15. The vehicle as claimed in claim 14 further comprising the plurality of antennas, wherein the first cluster of antennas comprises the same number of antennas as the second cluster of antennas.

16. The vehicle as claimed in claim 15, wherein the antennas of the first cluster have the same geometry with respect to one another as the antennas of the second cluster.

17. The vehicle as claimed in claim 15, wherein the antennas of the first cluster have the same antenna characteristic as the antennas of the second cluster.

18. The vehicle as claimed in claim 15, wherein the first cluster comprises other antennas than the second cluster.

19. A method for a transceiver for a vehicle for communication in a mobile radio system, comprising the acts of:

determining information about a radio channel between a first cluster of antennas of a plurality of antennas and a base station of the mobile radio system; and

communicating with the base station of the mobile radio system via a second cluster of the plurality of antennas.
