Reference signal generation method and apparatus

摘要

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.

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.
