Abstract: A carrier aggregation-based interference control method and apparatus for small base stations are disclosed. The present invention comprises setting a primary component carrier (PCC) as a first carrier and setting a secondary component carrier (SCC) as a second carrier, monitoring a signal-to-interference plus noise ratio (SINR) of the first carrier or the second carrier, and determining whether the SINR of the first carrier is smaller than a predetermined threshold.
