Abstract: A method and a device for controlling power in a TDD-based wireless communication system are provided. Particularly, a first resource block group for a first terminal and a second resource block group for a second terminal are configured. The first resource block group is configured in a partial frequency band of the entire frequency band. The maximum transmission power of the first terminal is controlled for the first resource block group according to the ratio between the number of subcarriers in the first resource block group and the number of subcarriers in the second resource block group. An uplink signal of the first terminal and an uplink signal of the second terminal are received through the first resource block group.
