Abstract

Techniques are provided for responding to congestion-sensitive preemptive data download requests in a V2X network. An example method for downloading data on a mobile device includes determining an estimated time of arrival at a station based at least in part on almanac information, generating a data download request based at least in part on the estimated time of arrival at the station, transmitting the data download request, and receiving one or more data packets from the station based on the data download request.

First claim

The invention claimed is:

1. A method for downloading data on a mobile device, comprising:
determining an estimated time of arrival at a first station based at least in part on almanac information;
generating a data download request based at least in part on the estimated time of arrival at the first station and a data transfer rate associated with the first station;
transmitting the data download request to a second station; and
receiving one or more data packets from the first station based on the data download request, wherein the data transfer rate associated with the first station is higher than a data transfer rate associated with the second station.

2. The method of claim 1 further comprising obtaining the almanac information from a network.

3. The method of claim 1 further comprising:
determining a data transfer gap duration based at least in part on the estimated time of arrival at the first station;
determining a data storage requirement based at least in part on the gap duration; and
generating the data download request based at least in part on the data storage requirement.

4. The method of claim 3 wherein the data storage requirement is based at least in part on an amount of data consumed by an application executing on the mobile device.

5. The method of claim 4 wherein the amount of data consumed by the application is based on a bit rate associated with a file type.

6. The method of claim 1 wherein the data download request is transmitted via a cellular network.

7. The method of claim 1 wherein the data download request is transmitted via a Uu interface.

8. The method of claim 1 wherein the data download request is transmitted via a sidelink interface.

9. The method of claim 1 wherein the one or more data packets are received via a PC5 interface.

10. The method of claim 1 wherein the one or more data packets are at least a first portion of a first media file.

11. The method of claim 10 further comprising:
determining an estimated time of arrival at a third station based at least in part on the almanac information;
generating a second data download request based at least in part on the estimated time of arrival at the third station;
transmitting the second data download request; and
receiving one or more data packets from the third station based on the second data download request, wherein the one or more data packets are at least a second portion of the first media file.

12. The method of claim 11 wherein the second data download request is transmitted to the second station.

13. The method of claim 1 wherein the data download request includes a priority value.

14. The method of claim 13 wherein the priority value is based at least in part on an amount of unconsumed media file on the mobile device.

15. The method of claim 1 further comprising:
storing the one or more data packets in a memory; and
displaying an indicator based on the one or more data packets stored in the memory.

16. An apparatus, comprising:
a memory;
at least one transceiver;
at least one processor communicatively coupled to the memory and the at least one transceiver and configured to:
determine an estimated time of arrival at a first station based at least in part on almanac information;
generate a data download request based at least in part on the estimated time of arrival at the first station and a data transfer rate associated with the first station;
transmit the data download request to a second station; and
receive one or more data packets from the first station based on the data download request, wherein the data transfer rate associated with the first station is higher than a data transfer rate associated with the second station.

17. The apparatus of claim 16 wherein the at least one processor is further configured to obtain the almanac information from a network.

18. The apparatus of claim 16 wherein the at least one processor is further configured to:
determine a data transfer gap duration based at least in part on the estimated time of arrival at the first station;
determine a data storage requirement based at least in part on the gap duration; and
generate the data download request based at least in part on the data storage requirement.

19. The apparatus of claim 18 wherein the data storage requirement is based at least in part on an amount of data consumed by an application executing on the apparatus.

20. The apparatus of claim 19 wherein the amount of data consumed by the application is based on a bit rate associated with a file type.

21. The apparatus of claim 16 wherein the at least one processor is further configured to transmit the data download request via a cellular network.

22. The apparatus of claim 16 wherein the at least one processor is further configured to transmit the data download request via a Uu interface.

23. The apparatus of claim 16 wherein the at least one processor is further configured to transmit the data download request via a sidelink interface.

24. The apparatus of claim 16 wherein the at least one processor is further configured to receive the one or more data packets via a PC5 interface.

25. The apparatus of claim 16 wherein the one or more data packets are at least a first portion of a first media file.

26. The apparatus of claim 25 wherein the at least one processor is further configured to:
determine an estimated time of arrival at a third station based at least in part on the almanac information;
generate a second data download request based at least in part on the estimated time of arrival at the third station;
transmit the second data download request; and
receive one or more data packets from the third station based on the second data download request, wherein the one or more data packets are at least a second portion of the first media file.

27. The apparatus of claim 26 wherein the at least one processor is further configured to transmit the second data download request to the second station.

28. The apparatus of claim 16 wherein the data download request includes a priority value.

29. The apparatus of claim 28 wherein the priority value is based at least in part on an amount of unconsumed media file on the apparatus.

30. The apparatus of claim 16 wherein the at least one processor is further configured to:
store the one or more data packets in the memory; and
display an indicator based on the one or more data packets stored in the memory.

31. An apparatus for downloading data on a mobile device, comprising:
means for determining an estimated time of arrival at a first station based at least in part on almanac information;
means for generating a data download request based at least in part on the estimated time of arrival at the first station and a data transfer rate associated with the first station;
means for transmitting the data download request to a second station; and
means for receiving one or more data packets from the first station based on the data download request, wherein the data transfer rate associated with the first station is higher than a data transfer rate associated with the second station.

32. The apparatus of claim 31 further comprising:
means for determining a data transfer gap duration based at least in part on the estimated time of arri
