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.

Method and apparatus for controlling power consumption in mobile communication system

A digital signal processing device of a base station configured to process down-link signals in a wireless communication system employing orthogonal frequency division multiple access (OFDMA) and a method of processing data in the device are provided. The device includes a clock controller configured to monitor whether a signal is allocated to an input and control a frequency of clocks to have a first or second characteristic based on the monitored result, and a data processor configured to process the input, and synchronize with the clock controlled by the clock controller.

Digital signal processing device of base station and method for processing data thereof

A method and apparatus of controlling transmission power in a transmitter of a wireless communication system are provided. The method includes generating a first signal to be transmitted to a receiver, identifying whether user data is allocated to the generated first signal, determining transmission power based on a result of the determination, and transmitting a second signal to the receiver, based on the determined transmission power and the first signal.
