1. An access control method, comprising:
sending, by a base station, physical broadcast channel (PBCH) information of a synchronization signal block (SSB) carrying access indication information, wherein
the access indication information indicates whether to allow access of first type user equipment, a maximum operating bandwidth of the first type user equipment being less than an operating bandwidth of second type user equipment,
the access indication information is carried in a spare bit of a payload field in the PBCH information, and the PBCH information further carries bandwidth information indicating a bandwidth for a common control resource set (CORESET) of Remaining Minimum System Information (RMSI), and
an indication from the bandwidth information is configured for the first type user equipment to determine whether the access is allowed.
