Claim:
1. A method for transmitting and receiving a signal to and from a user equipment by a base station in a wireless communication system, the method comprising: applying, by the base station, a first resource configuration among at least one candidate resource configuration to the base station; and transmitting and receiving, by the base station, the signal to and from the user equipment in a first subframe according to the first resource configuration, wherein the base station is grouped together with at least one neighboring base station into one group, wherein a reference resource configuration is applied to a representative base station of the group, wherein each of the at least one candidate resource configuration and the reference resource configuration indicates an uplink-downlink configuration for subframes in a TDD Time Division Duplex) system, wherein, if the first subframe is indicated as a downlink subframe by the first resource configuration and is indicated as an uplink subframe by the reference resource configuration, a transmit power of a downlink signal transmitted in the first subframe is reduced, and wherein, if the first subframe is indicated as a uplink subframe by the first resource configuration and is indicated as a downlink subframe by the reference resource configuration, a transmit power of a uplink signal received in the first subframe is reduced.
