FIELD: electrical communication engineering.
SUBSTANCE: invention relates to communication engineering and can be used in wireless communication systems. Method comprises: determining by a first device a first basic set of parameters used for transmitting a signal; determining, by a first basic set of parameters, by a first apparatus a first degree of precoding detail used for transmitting a signal; and use of first precoding detail for signal transmission between first device and second device.
EFFECT: technical result consists in improvement of efficiency of coding due to balance between gain from preliminary coding and efficiency of channel estimation.
