Method and station for transmitting data in a radio communication system

The present invention relates to the method of transmitting a data row in a radio communications system. By this method, in order that the 1st transmitting station (S1) may transmit a data row, a sending signal (C (t)) is transmitted to the 1st receiving station (R1) through radio interface (V), Before transmission, at least by the 1st transmitting station (S1) and/or the 1st receiving station (R1), A radio interface is inspected about the disturbance signal (I (t)) of a noise source (S2), and only when radio interface (V) is in a state without enough disturbance, transmission is started at a certain time (T0).
