1. A beam training method, comprising:
determining, by a first apparatus, a quasi co-location (QCL) assumption of a first reference signal, wherein the QCL assumption meets at least either of the following conditions: a plurality of periodic instances of the first reference signal at an interval of N periodicities have a same QCL assumption, wherein N is an integer greater than 0; and first reference signals that have different indexes and that are in a same resource set have different QCL assumptions; and
receiving, by the first apparatus based on the QCL assumption of the first reference signal, the first reference signal sent by a second apparatus.
