An apparatus and method of operating a compact base station for supporting coverage area expansion of a compact cell in a heterogeneous network system are provided. The method includes determining whether an overload takes place in a coverage area where a compact base station and a plurality of terminals communicate using a first Frequency Assignment (FA) in a compact cell, determining whether resources are redistributable using a second FA in a coverage area expanded according to coverage area expansion of the compact cell, and when the resources are redistributable using the second FA in the coverage area expanded according to the coverage area expansion of the compact cell, changing the FA of at least one of the plurality of terminals communicating with the compact base station using the first FA in the compact cell, from the first FA to the second FA.
