1. A phase noise estimation method, comprising:
obtaining, by a receive end, first information indicating a first parameter corresponding to interference information of a first phase tracking reference signal (PTRS), wherein the first parameter comprises one or more of a first phase set or a first amplitude set;
obtaining, by the receive end, a first signal, wherein the first signal is determined based on the first parameter and the interference information of the first PTRS, wherein an amplitude of the first signal meets a first threshold; and
determining, by the receive end based on the first information and the first signal, an estimated value of a phase noise corresponding to the first PTRS.
