Abstract: The present invention relates to a reference signal generation method and apparatus. In the reference signal generation method, cyclic shift values of a reference signal for a channel, output in a single frame, are calculated for respective slots constituting the single frame. The calculated cyclic shift values are stored. Base signal sequence phases of the reference signal for the channel, output in the single frame, are calculated for respective slots. The calculated base signal sequence phases are stored. A total phase of the reference signal is calculated based on the cyclic shift values and the base signal sequence phases previously stored for respective slots. A reference signal sequence is generated based on the calculated total phase.
