Abstract: A method for communication includes configuring a communication system that includes a transmitter and a receiver with first precoding matrices for mapping up to N data streams onto N transmit antenna ports 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 from the transmitter to the receiver.

Abstract: A method for communication includes, in a transmitter having a first number of transmit antenna ports, setting an upper limit on a second number of spatial layers to be used by the transmitter to be less than the first number. An actual number of the spatial layers, which does not exceed the upper limit, is allocated for transmission to a given receiver. One or more streams of modulated symbols are mapped onto the allocated actual number of the spatial layers. The actual number of the spatial layers are transmitted from the transmitter to the given receiver.

Abstract: A method includes, in a receiver, receiving a signal carrying data using multiple antennas, so as to produce multiple respective input signals. The input signals are divided into two or more subsets. The input signals within each of the subsets are combined in a first diversity-combining stage, to produce respective intermediate signals. In a second diversity-combining stage, the intermediate signals are combined to produce an output signal. The output signal is decoded so as to reconstruct the data carried by the received signal.
