Abstract

Systems and methods for file transfer by mobile user collaboration are provided. In some embodiments, a method of operation of a first wireless device for uploading a data file as multiple pieces to a destination network node in a wireless communications network includes dividing the data file into the multiple pieces; sending one or more pieces of the multiple pieces to one or more second wireless devices to be uploaded to the destination network node; and uploading one or more pieces via a Coordinated Multi-Point (CoMP) set of cooperating nodes in the wireless communication network. In this way, the first wireless device may be able to upload the data file to the destination network node faster than if the first wireless device uploads the entire date file directly.

First claim

What is claimed is:

1. A method of operation of a first wireless device for uploading a data file as a plurality of pieces to a destination network node in a wireless communications network comprising:
dividing the data file into the plurality of pieces;
sending one or more pieces of the plurality of pieces to one or more second wireless devices to be uploaded to the destination network node; and
uploading the one or more pieces of the plurality of pieces via a Coordinated Multi-Point, CoMP, set of cooperating nodes in the wireless communication network.

2. The method of claim 1 further comprising:
prior to sending the one or more pieces of the plurality of pieces, sending an upload assistance message to the one or more second wireless devices;
in response to the upload assistance message sent to the one or more second wireless devices, receiving an upload assistance confirmation message from the one or more second wireless devices; and
sending the one or more pieces of the plurality of pieces in response to the upload assistance confirmation message received from the one or more second wireless devices.

3. The method of claim 2 wherein sending the upload assistance message to the one or more second wireless devices and sending the one or more pieces of the plurality of pieces to the one or more second wireless devices are accomplished using Device-to-Device, D2D, communication.

4. The method of claim 1 further comprising:
creating a Data File Descriptor, DFD, which describes how the data file to be uploaded is partitioned into the plurality of pieces; and
sending an upload request message to a serving base station of the first wireless device.

5. The method of claim 4 further comprising:
in response to sending the upload request message, receiving a handshake message from the serving base station; and
in response to receiving the handshake message, sending a message to the serving base station including the DFD.

6. The method of claim 4 wherein the DFD comprises an indication of a size of each of the plurality of pieces to be uploaded to the destination network node.

7. The method of claim 6 wherein the indication of the size of each of the plurality of pieces in the DFD is an indication that the size of each of the plurality of pieces is a uniform size.

8. The method of claim 6 wherein the indication of the size of each of the plurality of pieces in the DFD is an indication of the size of each of the plurality of pieces where the size of each of the plurality of pieces may be variable.

9. The method of claim 6 wherein the indication of the size of each of the plurality of pieces in the DFD is an indication that the size of each of the plurality of pieces may be dynamic.

10. The method of claim 4 wherein the DFD comprises the size of each of the plurality of pieces that has been determined.

11. The method of claim 1 wherein sending the one or more pieces of the plurality of pieces to the one or more second wireless devices to be uploaded to the destination network node further comprises determining which pieces of the plurality of pieces to send to the one or more second wireless devices based on one or more of the group consisting of:
a number of pieces in the plurality of pieces;
a size of the pieces in the plurality of pieces;
a number of pieces the one or more second wireless devices is willing to upload; an amount of data the one or more second wireless devices is willing to upload; and
an upload bitrate of the one or more second wireless devices.

12. The method of claim 11 wherein retransmission of the one or more pieces of the plurality of pieces uploaded via the CoMP set of cooperating nodes is requested only if the CoMP set cannot correctly decode the one or more pieces of the plurality of pieces uploaded via the CoMP set using a soft combination of signals received at one or more nodes in the CoMP set.

13. The method of 12 wherein using the soft combination of signals received at the one or more nodes in the CoMP set comprises using the soft combination of signals received at more than one node in the CoMP set.

14. The method of claim 1 wherein the size of the pieces in the plurality of pieces is based on a channel quality from the one or more second wireless devices to one or more nodes in the CoMP set of cooperating nodes.

15. The method of claim 14 wherein retransmission of the one or more pieces of the plurality of pieces uploaded via the CoMP set of cooperating nodes is requested only if no node in the CoMP set correctly decoded the one or more of the plurality of pieces uploaded via the CoMP set.

16. The method of claim 1 wherein uploading the one or more pieces of the plurality of pieces via the CoMP set of cooperating nodes comprises receiving an upload grant from one or more cooperating nodes in the CoMP set.

17. The method of claim 1 wherein the destination network node is a serving base station of the first wireless device.

18. The method of claim 1 wherein the destination network node is a node in a core network of the wireless communications network.

19. The method of claim 1 wherein the one or more second wireless devices receive an incentive for uploading the one or more pieces of the plurality of pieces.

20. A method of operation of a second wireless device for uploading a data file as a plurality of pieces to a destination network node in a wireless communications network comprising:
receiving an upload assistance message from a first wireless device using Device-to-Device, D2D, communication;
in response to the upload assistance message received from the first wireless device, sending an upload assistance confirmation message to the first wireless device;
receiving one or more pieces of the plurality of pieces from the first wireless device to be uploaded to the destination network node using D2D communication in response to the upload assistance confirmation message sent to the first wireless device; and
uploading the one or more pieces of the plurality of pieces to the destination network node via a Coordinated Multi Point, CoMP, set of cooperating nodes in the wireless communication network.

21. The method of claim 20 wherein retransmission of the one or more pieces of the plurality of pieces uploaded via the CoMP set of cooperating nodes is requested only if no node in the CoMP set correctly decoded the one or more pieces of the plurality of pieces uploaded via the CoMP set.

22. The method of claim 20 wherein retransmission of the one or more pieces of the plurality of pieces uploaded via the CoMP set of cooperating nodes is requested only if the CoMP set cannot correctly decode the one or more pieces of the plurality of pieces uploaded via the CoMP set using a soft combination of signals received at each node in the CoMP set.

23. A method of operation of a destination network node in a wireless communications network for receiving a data file from a first wireless device as a plurality of pieces comprising:
receiving an upload request message from the first wireless device; and
receiving one or more pieces of the plurality of pieces from a network node that is a serving base station of a second wireless device where the second wireless device received the one or more pieces of the plurality of pieces from the first wireless device;
where the destination network node and the network node that is the serving base station of the second wireless device are part of a Coordinated Multi-Poin
