Abstract
Provided are a method and a device for avoiding interference of an uplink in a macro cell within a heterogeneous cellular network system. A femtocell base station calculates a degree of the interference of the uplink in the macro cell, and determines whether the interference is strong. If the interference of the uplink in the macro cell is strong, the femtocell base station changes the order of a femtocell uplink frame and a femtocell downlink frame.
