Claim Text:
1. A reference signal generation method in a wireless communication device, comprising: calculating cyclic shift values of a reference signal for a channel, output in a single frame with at least one of a control channel (PUCCH) and a data channel (PUSCH), for respective slots constituting the single frame; storing the calculated cyclic shift values in a memory; calculating base signal sequence phases of the reference signal for the channel, output in the single frame, for the respective slots; storing the calculated base signal sequence phases in said memory; calculating a total phase of the reference signal based on the cyclic shift values and the base signal sequence phases previously stored for the respective slots; and generating a reference signal sequence based on the calculated total phase and transmit the generated reference signal to another wireless communication device over a wireless network, wherein storing the calculated cyclic shift values and the calculated base signal sequence phases for the receptive slots reduce power consumption when generating the reference signal.
