FIELD: electrical communication equipment.
SUBSTANCE: invention relates to communication engineering and can be used in wireless communication systems for transmitting and receiving channel state information. To this end, H CSI matrix is decomposed to obtain a vector group, where the vector group contains at least two vector matrices, quantize information of elements of at least one vector matrix from the vector group and transmit the quantised information of the elements.
EFFECT: technical result consists in improvement of accuracy of determining state of transmission channel.
