Abstract
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.

31. 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, characterized by:
-
partitioning a data stream at the transmitting node into at least two data substreams; beamforming and transmitting each said data substream over a first link to a respective of said at least two relay nodes; forwarding at least one restorable representation of its received substream over a second link to the at least one receiving node from each of said at least two relay nodes; and multiplexing the received and decoded restorable/loss-free representations of each substream to form an output signal at said at least one receiving node corresponding to the data stream. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49)
