1. A signal transmission method, comprising:
receiving, by a first communication node, first indication information, and determining an acquisition mode for a sending beam of an uplink signal according to the first indication information, wherein the first indication information indicates whether the sending beam of the uplink signal is acquired according to a receiving beam of a downlink control channel;
acquiring, by the first communication node in a case that the first indication information indicates that the sending beam of the uplink signal is acquired according to the receiving beam of the downlink control channel, M sending beams, each of the M sending beams corresponds to one of M receiving beams of the downlink control channel;
determining, by the first communication node, N sending beams for sending the uplink signal from the M sending beams; and
sending, by the first communication node, the uplink signal to a second communication node by using the N sending beams;
wherein M is a natural number, and N is a natural number less than or equal to M;
wherein the uplink signal comprises one of: a signal over an uplink control channel, a signal over an uplink data channel, or an uplink measurement reference signal;
wherein the N sending beams from the M sending beams are determined according to a priority order corresponding to the M sending beams in a case where N is less than M, wherein the priority order of the M sending beams is agreed with the second communication node, and the priority order of the M sending beams is determined based on an indication from the second communication node.
