Claim 0:
1. A method comprising:
generating, by a terminal device, first indication information based on received precoded reference signals of P ports, the first indication information indicating Q ports in the P ports, the P ports corresponding to P angle-delay pairs respectively, and each of the P angle-delay pairs comprising an angle vector and a delay vector, wherein a precoded reference signal of each port of the P ports is a reference signal precoded based on the angle vector and the delay vector of a corresponding port of the P ports, the Q ports correspond to Q angle-delay pairs in the P angle-delay pairs, P>Q≥1, and P and Q are both integers; and
sending, by the terminal device, the first indication information.
