<p>The invention discloses a method for transmitting uplink control signalings, which includes: respectively performing, on the uplink control signalings, channel coding, scrambling, modulation, time-domain spreading and pre-coding transform, or respectively performing channel coding, scrambling, modulation, pre-coding transform and time-domain spreading; then, mapping the uplink control signalings to Orthogonal Frequency Division Multiplexing (OFDM) symbols which are used for bearing the uplink control signalings for transmission. The invention also discloses a method for bearing demodulation reference signals during the uplink control signaling transmission, which includes: bearing the uplink demodulation reference signals in k OFDM symbols of a sub-frame. The invention also discloses apparatuses respectively implementing the methods. The technical solutions effectively solve the problem that the uplink control signalings are transmitted using the structure of Discrete Fourier Transform-Spread-OFDM (DFT-s-OFDM).</p> |
