The embodiment of the invention discloses an indication and information determination method and device, and relates to the technical field of communication. The indication method comprises the stepsof: generating indication information, wherein the indication information is configured to indicate an emission wave beam set, and the emission wave beam in the emission wave beam set is configured tocarry the same DCI (downlink control information); and sending the indication information. The technical scheme can be applied to one or more than one network device to send the DCI to the terminal,and the DCI is carried in a scene where transmission is performed on at least one wave beam.
