Abstract
A method is provided, 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 the steps of: spatially decomposing channels into spatial subchannels; and selecting a subset of the subchannels for use that at least approximately maximises predicted throughput rate.
Claims15
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 the steps of:
- spatially decomposing channels into spatial subchannels;
- and
- selecting a subset of the subchannels for use that at least approximately maximises predicted throughput rate.
A wireless communications network comprising a source node, a destination node and at least one relay node, the network comprising a processor, the processor comprising a receiver stage operative to receive channel status information, a decomposer stage operative to decompose channels into spatial subchannels, a selector operative to select a subset of the spatial subchannels for use that at least approximately maximises predicted throughput rate, the network being operative to use the selected subchannels for data transmission.
A node for use in a wireless communications network, the node comprising a processor, the processor comprising a receiver stage operative to receive channel status information of channels between a source node, a destination node and at least one relay node;
- a decomposer stage operative to decompose channels into spatial subchannels;
- and a selector operative to select a subset of the spatial subchannels for use that at least approximately maximises predicted throughput rate.
