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.

File transfer by mobile user collaboration

Various methods, devices and nodes in a wireless system are disclosed for efficiently transferring files (both uploads and downloads) between a wireless device and a network node in a Coordinated Multipoint (CoMP) environment. According to a broad aspect, an upload request message is sent from the wireless device to the cooperating nodes in the CoMP set for uploading the data file to the network node, and based on an upload grant from at least one cooperating node, a plurality of piece messages are sent to the cooperating nodes for transmission to the network node, each piece message containing a particular piece of the data file. In yet another broad aspect, both a coordinating node and non-coordinating nodes in the CoMP set are configured to receive piece messages. Non-coordinating nodes that receive piece messages send acknowledgement messages to the coordinating node indicating which pieces have been received. If at least one piece has not been received at the coordinating node but received at a non-coordinating node, the coordinating node instructs the non-coordinating node to forward the at least one piece received to the network node.
