1. A method, performed by a first base station, of sharing a frequency resource with a second base station in a wireless communication system, the method comprising:
transmitting, to one or more channel measurement target terminals determined from among terminals communicating with the first base station using first frequency resources, information instructing to transmit a signal for channel measurement to the second base station;
transmitting, to the second base station, information indicating that the signal for channel measurement is to be transmitted from the one or more channel measurement target terminals;
receiving, from the second base station, measurement information about channels between the second base station and the one or more channel measurement target terminals, wherein the measurement information includes information about at least one first maximum transmission power of the second base station corresponding to the one or more channel measurement target terminals, which is determined by the second base station;
determining a shared frequency resource to be shared with the second base station from among the first frequency resources, based on the measurement information about the channels between the second base station and the one or more channel measurement target terminals; and
transmitting information about the shared frequency resource to the second base station,
wherein the at least one first maximum transmission power is determined based on information about a maximum allowable level of interference.
