FIELD: information technologies.
SUBSTANCE: method is suggested for data transfer in MIMO system of wireless communication, by means of transmitter having multiple antennas, moreover, in transmitter cyclic redundant code (CRC) is added to data unit, which should be transmitted, and mentioned data unit is spatially segmented according to modulator circuit and coding speed of every corresponding transmitting antenna from multiple antennas. In receiver transmitted units are received with the help of multiple receivers, and CRC code is checked to understand whether any mistake occurred during transmission. If it is defined that received data unit contains an error, receiver requests repeated transmission of mentioned data unit, preferably using functions of hybrid automatic repetition query (HARQ).
EFFECT: preservation of integrity in signal transmitted from array of transmitters antennas and confirmation of signal detection accuracy.
