Abstract

An access node, user equipment, an apparatus, method, and computer program for determining a delay-Doppler-resolution for a transceiver of a mobile communication system. The method for determining a delay-Doppler-resolution (DDR) for a transceiver of a mobile communication system includes determining information on properties of the transceiver, selecting the DDR from a database based on the information on the properties of the transceiver, and using the DDR for radio communication with the transceiver in the mobile communication system.

First claim

What is claimed is:

1. A method for determining a delay-Doppler-resolution (DDR) to provide adaptive radio performance for a transceiver of a mobile communication system, the method comprising:
determining information on properties of the transceiver;
selecting the DDR from a database based on the information on the properties of the transceiver;
using the DDR for radio communication with the transceiver in the mobile communication system, wherein the radio communication uses orthogonal time frequency and space (OTFS) multiplexing;
determining information on transceiver communication performance of the radio communication that uses OTFS multiplexing; and
tracking transceiver communication performance to determine how to adapt the DDR to further improve the transceiver communication performance to provide adaptive radio performance.

2. The method of claim 1 , further comprising improving the DDR based on the radio performance and updating the database.

3. The method of claim 2 , further comprising using artificial intelligence for improving the DDR based on the radio performance.

4. The method of claim 1 , wherein the information on the communication performance comprises information on a quality of service on a radio link.

5. The method of claim 1 , wherein the information on a communication performance comprises information on a diversity gain on the a radio link for the DDR.

6. The method of claim 1 , wherein the information on the properties comprises information on a velocity of the transceiver.

7. The method of claim 1 , wherein the information on the properties comprises information on a geographical position of the transceiver.

8. The method of claim 1 , wherein the information on the properties comprises information on a predicted trajectory of the transceiver.

9. The method of claim 1 , wherein the information on the properties comprises information on a transmitter and/or receiver setup of the transceiver.

10. The method of claim 1 , further comprising scheduling time and frequency resources to the transceiver, and wherein the selecting further comprises selecting the DDR based on the time and frequency resources.

11. The method of claim 1 , further comprising receiving user data from the transceiver, the user data at least partly comprising the information on the properties.

12. A non-transitory computer readable medium including a computer program having a program code for performing the method claim 1 , when the computer program is executed on a computer, a processor, or a programmable hardware component.

13. An apparatus for determining a delay-Doppler-resolution (DDR) to provide adaptive radio performance for a transceiver of a mobile communication system, the apparatus comprising:
a transceiver module for communicating in the mobile communication system; and
a processing module determine the DDR for the transceiver by determining information on properties of the transceiver, selecting the DDR from a database based on the information on the properties of the transceiver, using the DDR for radio communication with the transceiver in the mobile communication system, wherein the radio communication uses orthogonal time frequency and space (OTFS) multiplexing, determining information on transceiver communication performance of the radio communication that uses OTFS multiplexing, and tracking transceiver communication performance to determine how to adapt the DDR to further improve the transceiver communication performance to provide adaptive radio performance.

14. The apparatus of claim 13 , wherein the processing module improves the DDR based on the radio performance and updates the database.

15. The apparatus of claim 14 , wherein the processing module uses artificial intelligence to improve the DDR based on the radio performance.

16. The apparatus of claim 13 , wherein the information on the communication performance comprises information on a quality of service on a radio link.

17. The apparatus of claim 13 , wherein the information on a communication performance comprises information on a diversity gain on a radio link for the DDR.

18. The apparatus of claim 13 , wherein the information on the properties comprises information on a velocity of the transceiver.

19. The apparatus of claim 13 , wherein the information on the properties comprises information on a geographical position of the transceiver.

20. The apparatus of claim 13 , wherein the information on the properties comprises information on a predicted trajectory of the transceiver.

21. The apparatus of claim 13 , wherein the information on the properties comprises information on a transmitter and/or receiver setup of the transceiver.

22. The apparatus of claim 13 , wherein the processing module schedules time and frequency resources to the transceiver, and wherein the selection selects the DDR based on the time and frequency resources.

23. The apparatus of claim 13 , wherein the processing module receives user data from the transceiver, the user data at least partly comprising the information on the properties.
