METHOD AND ARRANGEMENT FOR COOPERATIVE RELAYING

摘要

In a method for relaying deployment in a wireless communication system comprising a transmitting node with multiple antennas for communicating with at least one receiving node via at least two relay nodes, a data stream at the transmitting node is partitioned into at least two data substreams, each of which is beamformed and transmitted over a first link to a respective of the relay nodes; subsequently at least one restorable representation of each received substream is forwarded over a second link to the receiving node from the two relay nodes; and finally the received and decoded representations are multiplexed to form an output signal at the receiving node corresponding to the original data stream.
