Transmitting uplink control signaling, uplink demodulation reference signal carrier method and apparatus

The present invention discloses a method for transmitting kinds uplink control signaling, comprising: an uplink control signaling channel coding, scrambling, modulation, time-domain spreading and the pre-code conversion, respectively, or each channel coding, scrambling, modulation, pre encoded transform and time domain spreading, mapped to a quadrature for carrying the uplink control signaling transmitted on a frequency division multiplexing (OFDM) symbols. The present invention also discloses a method of demodulating the carrier when transmitting uplink control signaling types of reference signals, comprising: an uplink demodulation reference signal is carried on a subframe k OFDM symbol. The present invention also discloses a device for realizing the method, respectively. Aspect of the present invention effectively solves the problem of uplink control signaling using DFT-s-OFDM transmission structure.
