Classification: CPC H | IPC H

Claim 4:
5. The method according to claim 3, wherein determining, by the first device, that X far-end reflected interference signal cancellations need to be performed comprises:
obtaining, by the first device, a kth delay parameter and a (k+1)th delay parameter, wherein the kth delay parameter is a third interference signal resulting from a kth far-end reflection, the (k+1)th delay parameter is a fourth interference signal resulting from a (k+1)th far-end reflection, and k is a positive integer;
determining, by the first device based on the kth delay parameter and the (k+1)th delay parameter, a length of an intermediate frequency cable that connects the first device and the second device; and
determining, by the first device based on the length of the intermediate frequency cable, that the X far-end reflected interference signal cancellations need to be performed.
