PROBLEM TO BE SOLVED: To provide a method for communication that comprises configuring a communication system including a transmitter and a receiver.SOLUTION: The communication system has first precoding matrices for mapping up to N data streams onto N transmit antenna ports 52 of the transmitter. Each of at least some of the first precoding matrices are derived from respective second and third precoding matrices. The second and third precoding matrices are configured for mapping data onto respective numbers of transmit antenna ports that are less than N. The data streams are mapped onto the N transmit antenna ports using a precoding scheme based on one of the first precoding matrices. The mapped data streams are transmitted over the N transmit antenna ports to the receiver. |
