FIELD: radio engineering, communication.
SUBSTANCE: method comprises: obtaining channel state information by the terminal, performing joint coding of PMI1 information and rank indicator (RI) information by the terminal to a 4-bit or a 5-bit feedback report, or performing joint coding of PMI1 information and PMI2 information to a 4-bit feedback report, or PMI2 information using a 2-bit feedback signal; and transmitting a feedback report by the terminal by feedback on a physical uplink control channel.
EFFECT: precision transmission of precoding matrixby feedback with reduced costs and improved performance of precoding.
