An apparatus and method for initial ranging in a wireless communication system including a heterogeneous network. An operation of a terminal includes selecting a serving cell considering a biased value of a base station applying range expansion. The operation also includes receiving ranging code classification information and threshold information associated with the serving cell. The operation further includes, if a channel quality with the serving cell is less than the threshold, selecting one a plurality of poor-expected-ranging codes indicated by the ranging code classification information, and performing initial ranging using the selected poor-expected-ranging code.
