Abstract
A method for wireless communication at a first wireless device and related apparatus are provided. In the method, the first wireless device communicates a first reference signal with a second wireless device based on a first frequency-modulated continuous wave (FMCW). The first wireless device further communicates a second reference signal with the second wireless device. The second reference signal is based on a second FMCW and has a second frequency bandwidth. The second frequency bandwidth is smaller than the first frequency bandwidth of the first reference signal, and the second reference signal has a frequency location based on the first reference signal. The first wireless device further communicates data with the second wireless device based on a channel estimation for a channel between the first wireless device and the second wireless device based on the second reference signal.
