Patent ID: 8817687

Claim:
A method for operations at a first communications device, the method comprising: transmitting a first pilot signal; receiving, on a channel from a relay node, a first combined signal comprising a retransmission of the first pilot signal, and comprising first non-pilot data information relayed from a second communications device; buffering the first non-pilot data information; transmitting second non-pilot data information; receiving, on the channel from the relay node, a second combined signal comprising a retransmission of the second non-pilot data information, and comprising a second pilot signal relayed from the second communications device; computing an estimate of the channel between the second communications device and the first communications device in accordance with the second combined signal; removing self-interference from a composite transmission relayed to the first communications device from the relay node, wherein the composite transmission comprises first data transmissions from the first communications device and second data transmissions from the second communications device; detecting transmitted data information contained in the second data transmissions from the second communications device from the composite transmission in accordance with the estimate of the channel: and detecting buffered data information contained in the buffered first non-pilot data information in accordance with the estimate of the channel, after computing the estimate of the channel.
