Claim 10:
11. A communications apparatus, comprising:
at least one processor; and
a memory configured to store a computer program that, when executed by the at least one processor, causes the at least one processor to:
generate 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
send the first indication information.
