Abstract: An embodiment of the present disclosure may provide a power consumption controlling method and apparatus. An embodiment of the present disclosure may provide a method and apparatus for controlling power consumption by a base station, the method including determining empty symbol duration in at least one subframe; and performing a power amplifier (PA) on/off operation based on the determination result. Further, an embodiment of the present disclosure may provide a method and apparatus for controlling power consumption by a base station, the method including generating baseband in-phase/quadrature-phase (IQ) data; determining whether the baseband IQ data includes data which must be transmitted for a predetermined time; and controlling a PA on/off based on the determination result and a transient of the PA.

Abstract: A wireless remote access base station for converting a downstream optical signal to a downstream radio frequency (RF) signal, transmitting the converted downstream RF signal wirelessly, converting a received upstream RF signal to an upstream optical signal, and transmitting the upstream optical signal is provided. The remote base station includes: an electro-absorption modulator (EAM) for converting a downstream optical signal to a downstream RF signal and an upstream RF signal to an upstream optical signal; an antenna for transmitting the downstream RF signal wirelessly and outputting the upstream RF signal received wirelessly to the EAM; and an amplifier, which is located between the EAM and the antenna, amplifies the downstream RF signal and outputs the amplified downstream RF signal to the antenna.
