1. A beam scanning method, comprising:
determining, by a first communication node, at least one transmission beam according to an optimum group of reception beams between a receiver of the first communication node and a transmitter of a second communication node; wherein at least one beam is selected from a set of transmission beams as the at least one transmission beam; and the set of transmission beams comprises a part or all of beams in the optimum group of reception beams, or the set of transmission beams comprises a part of all available beams determined by centering on each of a part or all of beams in the optimum group of reception beams;
transmitting, by the first communication node, a signal to the second communication node through a transmitter of the first communication node using the determined at least one transmission beam in sequence until an optimum transmission beam is determined; and
wherein identification information of a part or all of beams in an optimum group of transmission beams, corresponding to the optimum group of reception beams, of the transmitter of the second communication node is carried in the signal transmitted by the first communication node to the second communication node through the transmitter of the first communication node using the determined at least one transmission beam.
