Abstract: A beam information indication method includes receiving, by a terminal, a first command sent by a network side device, the first command being used to activate or indicate at least one unified transmission configuration indicator TCI state ID; and determining, by the terminal, a unified TCI state of a channel or a reference signal in a component carrier CC group based on the unified TCI state ID. A target unified TCI state ID in the at least one unified TCI state ID is associated with a target channel or a target reference signal in the CC group.
