A method and a device for measuring interference in a communication system are provided. The method includes measuring interference in a base station of a communication system, in which one or more antenna groups are arranged at different positions in a single cell, includes the steps of determining a reception antenna group which is one of the one or more antenna groups that transmits a signal other than an interference signal to a terminal, determining a reference signal in order to measure the strength of the signal transmitted by the reception antenna group, a step of determining a wireless resource so as to measure the interference in each of the one or more antenna groups, and notifying the terminal with the strength of the signal transmitted by the reception antenna group and information for measuring the interference in each of the one or more antenna groups.
