FIELD: radio engineering, communication.
SUBSTANCE: method of transmitting uplink control signals includes: Performing, for uplink control signals, channel coding, scrambling, modulation, time-domain spreading and precoding transform; or respectively performing, for the uplink control signals, channel coding, scrambling, modulation, precoding transform and time-domain spreading; and mapping the uplink control signals to an OFDM symbol used for bearing the uplink control signals; and transmitting the uplink control signals borne in the OFDM symbol. The disclosure also provides a method for bearing a demodulation reference signal during transmission of uplink control signals, which includes: bearing the uplink demodulation reference signal in k OFDM symbols in a sub-frame.
EFFECT: effectively solving the problem of transmitting uplink control signals using a discrete Fourier transform-spread-OFDM structure.
