Abstract

A method for simulating a communication system, and simulation system for a communication system and computer program, the communication system having a communication protocol which regulates a communication between at least two transmitter-receivers of the communication system via a common communication channel in such a way that a first transmitter-receiver transmits a data packet only when no use of the communication channel by a second transmitter-receiver is indicated to the first transmitter-receiver, includes sending a data packet by at least the first transmitter-receiver via the common communication channel even when at least the second transmitter-receiver is using the communication channel.

Claims

1. A method for simulating a communication system having a communication protocol which regulates a communication between at least two transmitter-receivers of the communication system via a common communication channel in such a way that a first transmitter-receiver transmits a data packet only when no use of the communication channel by a second transmitter-receiver is indicated to the first transmitter-receiver, comprising:

sending a data packet by at least the first transmitter-receiver via the common communication channel even when at least the second transmitter-receiver is using the communication channel.

2. The method according to claim 1, further comprising:

modifying a return signal to include information about a release of the channel irrespective of an actual usage of the channel.

3. The method according to claim 2, the modifying step further comprising:

modifying the return signal to include a remaining time value until a release of the channel of zero irrespective of an actually remaining time value.

4. The method according to claim 1, further comprising:

damping a direction from the group of an uplink direction of the communication channel and a downlink direction of the communication channel in such a way that no usage of the communication channel by the second transmitter-receiver is indicated to the first transmitter-receiver.

5. The method according to claim 4, wherein a damped representation of an input signal on a first terminal of a circulator through the second transmitter-receiver is provided on a second terminal of the circulator.

6. The method according to claim 4, further comprising:

temporarily damping an additional direction from the group of the uplink direction and the downlink direction in such a way that no usage of the communication channel by the first transmitter-receiver is indicated to the second transmitter-receiver.

7. The method according to claim 6, further comprising:

transmitting a first representation of an input signal originating from the second transmitter-receiver via the uplink direction; and

transmitting a second representation of the input signal originating from the second transmitter-receiver via the downlink direction by way of a signal splitter.

8. The method according to claim 6,

wherein the temporary damping occurs by way of an isolator segment between the first transmitter-receiver and the second transmitter-receiver;

and

wherein a control element provides a control signal to the isolator segment, which effects a modification of the temporary damping such that a usage of the communication channel by a second transmitter-receiver is indicated to the first transmitter-receiver.

9. A system for simulating a communication system having a communication protocol which regulates a communication between at least two transmitter-receivers of the communication system via a common communication channel in such a way that a first transmitter-receiver transmits a data packet only when no use of the communication channel by a second transmitter-receiver is indicated to the first transmitter-receiver, the system comprising:

program code executable on a computer, a processor, or a programmable hardware component, the program code configured to;

send a data packet by at least the first transmitter-receiver via the common communication channel even when at least the second transmitter-receiver is using the communication channel.

10. The system according to claim 9, the program code further configured to:

modify a return signal to include information about a release of the channel irrespective of an actual usage of the channel; and

modify the return signal to include a remaining time value until a release of the channel of zero irrespective of an actually remaining time value.

11. The system according to claim 10, the program code further configured to:

modify the return signal to include a remaining time value until a release of the channel of zero irrespective of an actually remaining time value.

12. The system according to claim 10, the program code further configured to:

damp a direction from the group of an uplink direction of the communication channel and a downlink direction of the communication channel in such a way that no usage of the communication channel by the second transmitter-receiver is indicated to the first transmitter-receiver

13. The system according to claim 12, the program code further configured to:

temporarily damp an additional direction from the group of the uplink direction and the downlink direction in such a way that no usage of the communication channel by the first transmitter-receiver is indicated to the second transmitter-receiver.

14. The system according to claim 13, the program code further configured to:

transmit a first representation of an input signal originating from the second transmitter-receiver via the uplink direction; and

transmit a second representation of the input signal originating from the second transmitter-receiver via the downlink direction by way of a signal splitter.

15. A simulation system for a communication system having a communication protocol which regulates a communication between at least two transmitter-receivers of the communication system via a common communication channel in such a way that a first transmitter-receiver transmits a data packet only when no use of the communication channel by a second transmitter-receiver is indicated to the first transmitter-receiver, comprising:

the at least two transmitter-receivers, including the first and second transmitter-receivers;

wherein at least the first transmitter-receiver is configured to transmit a data packet via the common communication channel even when at least the second transmitter-receiver is using the communication channel.

16. The simulation system according to claim 15, wherein a circulator is connected between the first transmitter-receiver and the second transmitter-receiver, such that a first terminal of the circulator is connected to the first transmitter-receiver and a second terminal of the circulator is connected to the second transmitter-receiver such that the data packet originating from the first transmitter-receiver is provided on the second terminal of the circulator, and a damped representation of an input signal originating from the second transmitter-receiver is provided on the first terminal of the circulator.

17. The simulation system according to claim 16,

wherein the first transmitter-receiver is connected to the second transmitter receiver via an isolator segment;

wherein the isolator segment effects a damping of an input signal originating from the second transmitter-receiver;

wherein the isolator segment is connected to a control element; and

wherein the control element provides a control signal to the isolator segment, which effects a modification of a damping of the additional input signal in such a way that a usage of the communication channel by a second transmitter-receiver is temporarily indicated to the first transmitter-receiver.
