1. A device, comprising:
a receiver configured to: receive a first reference signal and a second reference signal sent over a wireless network from a first transmit and receive point (TRP), the first reference signal corresponding to a quasi-colocation reference signal (QCL RS) of the second reference signal, determine delay-spread and average-delay information for a path from the first TRP to the device based on the first reference signal;
receive a third reference signal from a second TRP, the third reference signal corresponds to a QCL RS of a fourth reference signal transmitted from the second TRP or corresponds to the second reference signal transmitted in a Single Frequency Network (SFN) manner from the first TRP; and
determine Doppler-shift and Doppler-spread information for a path from the second TRP to the device based on the third reference signal.
