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 for communication includes modulating data in a wireless communication terminal to produce an aggregated-spectrum signal, which includes at least first and second signals in respective first and second spectral bands. The modulated data is transmitted in the first and second signals at respective first and second power levels. The second power level is adjusted separately from the first power level. In some embodiments, one or more instructions to set the first power level are received at the wireless communication terminal, and the first power level is set separately from setting the second power level based on the instructions.
