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.

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.
A communication system comprising at least one transmitting node capable of communicating a data stream to at least one receiving node via at least two relay nodes, characterized by:
- means for partitioning the data stream at the transmitter node into multiple data substreams;
- means for beamforming and transmitting each said data substream over a first link to a respective of said at least two relay nodes;
- and
- means for receiving and forwarding restorable representations of each said data substream over a second link to the receiving node;
- means for receiving and multiplexing said restorable representations of each said substream to an output signal corresponding to the transmission data stream.
An transmitter node capable of communicating a data stream to at least one receiving node via at least two relay nodes, characterized by:
- means for partitioning the data stream into at least two data substreams;
- means for beamforming and transmitting each said at least two data substreams over a first link to a respective of said at least two relay nodes.
A relay node enabling relaying deployment in a wireless communication system, said system comprising a transmitting node with multiple antennas communicating with at least one receiving node via at least two relay nodes, characterized by:
- means for forwarding a restorable representation of a received substream over a second link to the at least one receiving node;
- and
- means for providing channel state information for at least one of said first and said second link to the transmitting node.
A receiver node capable of receiving a partitioned data stream from a transmitting node with multiple antennas over a first link via at least two relay nodes, characterized by:
- means for receiving restorable representations of at least one data substream over a second link from each of the at least two relay nodes,
- means for multiplexing the received and decoded restorable representations to form an output signal corresponding to the data stream at the transmitting node.
