1. A beam training method, comprising:
determining, by a transmitting end, a first mapping relationship comprising a mapping relationship among Beam Pair Link, BPL, identifiers, Channel state information reference signal Resource Indicators, CRIs, and transmitting beams;
configuring, by the transmitting end, first reference signal resource for a receiving end, and transmitting configuration information of the first reference signal resource to the receiving end, wherein the configuration information comprises a first BPL identifier;
determining, by the transmitting end, a first transmitting beam; and
transmitting, by the transmitting end, a reference signal to the receiving end, by using the first transmitting beam within the first reference signal resource, so that the receiving end receives the reference signal on the first reference signal resource.
