In a MIMO communications system a communication device receives one or more receive signals on at least one receiver port. A receiver unit recovers, from the at least one receive signal, at least a first transmit signal transmitted to the receiving communication device via a transmission channel. A multi-link decoder unit decodes the receive signals using a multi-link decoder algorithm with parameters derived from a first channel state information describing the transmission channel and second channel state information describing at least one interference channel via which one or more second transmit signals arrive at the communication device.
