AI Technical Summary
In existing wireless sensing technologies, improper setting of the frequency domain spacing of the sensing reference signal leads to low spectral efficiency, insufficient power, or timing ambiguity, making it difficult to achieve high-precision distance, azimuth angle, and velocity estimation.
By determining the parameters of the subcarrier positions, two sets of positions indicating the subcarrier positions are generated, and a non-uniformly distributed set of subcarrier positions is generated based on these sets for transmitting and receiving sensing reference signals.
This improves the spectral efficiency of the sensing reference signal and the time-domain resolution of the receiver, reduces resource overhead and total transmission power, and achieves higher sensing accuracy and performance.
