Abstract

A method for organizing the communication between mobile radio network subscriber stations in a mobile radio cell, wherein a mobile radio network management unit, especially the scheduler of a base station, in the mobile radio cell performs the allocation of the radio resources. The mobile radio network management unit defines for the mobile radio cell a number of subradio areas in which a number of mobile radio subscriber stations are allowed to use the same radio resources for direct communication with one another in parallel operation.

First claim

The invention claimed is:

1. A method for organizing communication between mobile radio network subscriber stations in a mobile radio cell, the method comprising:
performing allocation of radio resources by a mobile radio network management unit in the mobile radio cell by:
measuring characteristics of interference by obtaining a signal from potential mobile radio network subscriber station interferers;
defining by the mobile radio network management unit subradio areas based on the measured characteristics;
allowing mobile radio subscriber stations within a defined subradio area to use the same radio resources for direct communication with one another in parallel operation; and
utilizing map data to correlate the subradio areas to shielded geographic areas.

2. The method of claim 1 , the geographic areas correspond to individual street routes.

3. The method of claim 1 further comprising determining subradio areas based on the subscriber stations disturbed by the parallel operation of subscriber stations which perform the direct communication.

4. The method of claim 3 further comprising determining conditions at the disturbed subscriber stations by allocating a measurement interval during which measurements performed by the disturbed subscriber stations and a corresponding uplink test signal from subscriber stations which are tested for the parallel operation are sent out to the mobile radio network management unit.

5. The method of claim 3 , wherein the measurements relate to measurements of the received signal strength or the interference power of the uplink test signal.

6. The method of claim 3 , further comprising conveying to a base station by a subscriber station that is planning a direct communication information with respect to the direct communication.

7. The method of claim 6 wherein the information about the radio characteristics of interference correspond to position of, transmitting power of, antenna type and/or the operation used by the potential mobile radio network subscriber station interferers.

8. The method of claim 1 , wherein the direct communication between two subscribers corresponds to a direct vehicle communication between at least two vehicles or to a communication between a vehicle and an infrastructure component.

9. The method of claim 8 , wherein an antenna technology with beam alignment possibility is used for the direct vehicle communication, the method further comprising receiving by the base station information with respect to a setting of the beam alignment to the base station from the vehicles which perform the direct vehicle communication.

10. The method of claim 9 , further comprising using lookup tables are for the information with respect to the setting of the beam alignment and during the transmission of the information with respect to the setting of the beam alignment, and transmitting an index value for the corresponding entry in the lookup table.

11. A mobile radio network subscriber station for use in a method for organizing communication between mobile radio network subscriber stations in a mobile radio cell, comprising:
a mobile radio network management unit in the mobile radio cell configured to perform allocation of radio resources by:
measuring characteristics of interference by obtaining a signal from potential mobile radio network subscriber station interferers;
defining by the mobile radio network management unit subradio areas based on the measurement characteristics;
utilizing map data to correlate the subradio areas to shielded geographic areas;
allowing mobile radio subscriber stations within a defined subradio area to use the same radio resources for direct communication with one another in parallel operation;
determining subradio areas based on the subscriber stations disturbed by the parallel operation of subscriber stations which perform the direct communication; and
determining conditions at the disturbed subscriber stations by allocating a measurement interval during which measurements performed by the disturbed subscriber stations and a corresponding uplink test signal from subscriber stations which are tested for the parallel operation are sent out to the mobile radio network management unit.

12. The mobile radio network subscriber station of claim 11 further comprising:
a radio communication module, the radio communication module being an equipment component of a vehicle, wherein the vehicle is equipped for the direct vehicle communication with an antenna technology with beam alignment possibility; and
wherein the radio communication module is configured to convey the information with respect to setting of the beam alignment to a base station.

13. The mobile radio network management unit of claim 12 , wherein the mobile radio network management unit is configured to receive information with respect to the setting of the beam alignment from a vehicle equipped for direct vehicle communication with an antenna technology having beam alignment possibility and specify the subradio areas based on the beam alignment setting information.
