1. A method for uplink beam indication, comprising:
dynamically indicating, by a base station, a transmission beam of a first uplink signal, to a terminal through transmission beam indication information; wherein:
the first uplink signal is a signal transmitted on a physical uplink shared channel PUSCH), the transmission beam indication information is used to indicate one or more reference signals from a plurality of candidate reference signals, the candidate reference signals comprise a reference signal other than a first reference signal, and the first reference signal is a reference signal corresponding to an uplink reference signal resource that is configured by the base station for the terminal and is used for acquiring channel state information (CSI) in an uplink transmission mode corresponding to the PUSCH.
