1. A beam indication method, comprising:
receiving beam indication information transmitted by a network-side device, wherein the beam indication information is used to indicate a plurality of pieces of beam information of a channel or a reference signal, and the plurality of pieces of beam information correspond to different transmission and reception point TRP identification information; and
transmitting the channel or the reference signal according to the beam indication information;
wherein the reference signal comprises the CSI-RS; and before the transmitting the channel or the reference signal according to the beam indication information, the method further comprises:
if the CSI-RS is an aperiodic CSI-RS, and a scheduling offset between DCI and the aperiodic CSI-RS is less than or equal to a preset offset threshold, and there is another downlink signal on a symbol on which the CSI-RS is located, determining TCI state information of the CSI-RS based on TCI state information of the another downlink signal;
or,
wherein the reference signal comprises the SRS; and the beam indication information comprises:
a plurality of pieces of spatial relation information, wherein the plurality of pieces of spatial relation information correspond to different TRP identification information.
