1. A method, in a wireless communications network comprising a source node, a destination node and at least one relay node, of selecting spatial subchannels for use, the method comprising:
via a destination node processor, spatially decomposing channels into spatial subchannels, the subchannels into which the channels are decomposed comprising the subchannels from the source node to each relay node and the subchannels from each relay node to the destination node, wherein the subchannels have the same frequency; and via the destination node processor, selecting a subset of the subchannels for use that at least approximately maximises predicted throughput rate; in which the network is a MIMO network in which the source node and the destination node each comprise a plurality of antennas; and transmitting data over the selected subchannels. |
