FIELD: radio engineering, communication.
SUBSTANCE: invention is allocated for transmitting a sounding reference signal in accordance in accordance with antenna pattern in which a sounding reference signal is transmitted over the entire bandwidth of the uplink data transmission system for each terminal antenna without additional overhead to this medium. A terminal using the multiple antenna method is equipped with a plurality of antennas and the base station receives a sounding reference signal transmitted from these antennas and estimates the uplink channel state of each antenna. In addition, the sounding reference signal jumps in frequency so that the base station determines the channel conditions for the entire bandwidth in which data is transmitted in the uplink system.
EFFECT: increasing the transmission speed.
