Original Abstract Submitted
A beam indication method, a beam indication apparatus, a terminal and a base station are provided. The method includes: receiving a first configuration of each candidate reference carrier in a carrier list, where the first configuration includes a transmission configuration indicator (TCI) state pool configured for each candidate reference carrier; determining a reference carrier from the candidate reference carrier; receiving a common TCI state index from a base station, where the common TCI state index is used to indicate a TCI state in a TCI state pool corresponding to the reference carrier; and determining, based on the TCI state indicated by the common TCI state index, a beam direction for channel transmission and/or reference signal transmission on each carrier in the carrier list.
