An apparatus and method for controlling power in a communication system are provided. The method includes amplifying an input signal by a second processor farther from an antenna than a first processor, and determining whether to enable or disable each of the first processor and the second processor based on results from the amplification by the second processor. Another method includes amplifying an input signal from an antenna by a second processor electrically farther from the antenna than a first processor, and determining whether to operate the first processor and the second processor based on a value related to a reception state for the amplified signal by the second processor.
