Classification: CPC H | IPC H

Claim 15:
16. A communications apparatus, comprising:
at least one processor;
a memory configured to store a computer program that, when executed by the at least one processor, causes the at least one processor to:
receive first indication information, wherein the first indication information is based on precoded reference signals of P ports sent by the communications apparatus and the first indication information indicates 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
determine, based on the first indication information, the Q angle-delay pairs corresponding to the Q ports.
