Systems and methods are provided for broadcasting a signal. A multiplexer combines a first signal from a first signal source and a second signal from a second signal source as a time divisional multiplexed signal and provides a timing signal, distinct from the time division multiplexed signal, that indicates, for a given time, from which of the first and the second signal source a corresponding portion of the time divisional multiplexed signal originated. A signal conditioning component receives each of the time divisional multiplexed signal and the timing signal and alters the time division multiplexed signal in a manner that prepares the signal for broadcast. The signal conditioning component dynamically alters its behavior according to the timing signal. An antenna transmits the time division multiplexed signal.

The present application discloses a method for transmitting, by a base station, a broadcast channel through a massive multiple-input multiple output (MIMO) antenna in a wireless communication system. Specifically, the method comprises the steps of: selecting broadcast channel dedicated antenna elements from among all antenna elements of the massive MIMO antenna; and transmitting the broadcast channel by performing a beamforming using the broadcast channel dedicated antenna elements. In the present invention, the power applied to the broadcast channel dedicated antenna elements in greater than the voltage applied to the remaining antenna elements.
