FIELD: information technology.
SUBSTANCE: method for data transmission in "wireless communication system using time division duplex (TDD)" includes steps in which: pilot reference signal is received via uplink; noise and interference for uplink are evaluated based on pilot reference signal; noise and interference asymmetry is determined for downlink and uplink based on link quality indicator information in downlink and evaluated noise and interference for uplink; noise and interference for downlink are evaluated based on evaluated noise and interference for uplink and asymmetry; precoding matrix is determined based on pilot reference signal; at least one modulation and coding scheme is determined based on evaluated noise and interference for downlink; and send data transmission via downlink based on precoding matrix and at least one modulation and coding scheme.
EFFECT: high communication quality.
