FIELD: communications.
SUBSTANCE: method and device for transmission of upstream communication line acknowledgement information (ACK) in communication system which uses multiple access scheme with orthogonal frequency division multiplexing (OFDMA) includes data bit receiving for upstream communication line ACK; output of code words corresponding to data bit; modulation execution by quadrature phase shift keying (QPSK) on characters for ACK vector indices matching to code words for received data bit; execution of inverse fast Fourier (IFFT) on transmission signal containing subcarrier groups to which modulated transmission characters are assigned; and transmission of processed by IFFT transmission signal.
EFFECT: reliability enhancement for transmission of upstream communication line acknowledgement information (ACK) and reduction of service protocol data portion.
