An information indication method includes: adding time-frequency indication information configured for a CORESET of RMSI to a PBCH of a SSB; if the time-frequency indication information indicates the CORESET of RMSI and the SSB are multiplexed in time division, querying a pre-stored correlation according to a present band, an SCS of the SSB and an SCS of the CORESET of RMSI to obtain an extended RB offset minimum set corresponding to the present band; an RB offset is selected from the obtained extended RB offset minimum set, and adding an offset index of the selected RB offset to the time-frequency indication information; and sending the SSB comprising the time-frequency indication information to UE in a beam scanning manner.
