摘要： In one novel aspect, OFDM RS symbols are configured with zero-power RS occupying either all even subcarrier or all odd subcarriers and the non-zero-power RS occupy all or part of remaining subcarriers. In one embodiment, even component RS symbols and odd component RS symbols are alternatively inserted in data frames with frequency offsets. In one embodiment, the receiver performs a wireless sensing by sampling a final-half duration with phase preprocessing. In one novel aspect, the target distance and velocity are uniquely determined via estimating clustering-range rate during successive CPIs. In one embodiment, the UE performing successive sensing for multiple clusters based on the diamond-shaped RS configuration during N successive CPIs, and a range rate for each cluster, selects a cluster with velocity that matches the calculated range rate, and determines a target distance and velocity based on the selected cluster.
