Patent ID: 7929477

Claim:
A method for data transmission in a radio communication network in which a branch between a source and a sink comprises a number of nodes and each node is designated by a hop number, comprising: setting up a basic frame for the data transmission, wherein the basic frame comprises a number of subframes; determining a hop number of the branch; allocating, consecutively, a transmission resource in a subframe to a link of the branch starting from the link with the lowest hop number; and if the hop number of the branch is greater than the number of the subframes, reusing the transmission resources of the subframes by allocating, consecutively, a transmission resource in a subframe to a link of the branch starting from the link with the hop number greater than the number of the subframes until all the links are allocated with a transmission resource in a subframe; wherein the hop number of the branch is the number of total hops between the source and the sink, and a link with a hop number of N is a link between a node with a hop number of N−1 and a node with a hop number of N in the branch.
