Abstract
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.
