摘要:
An apparatus and method for reducing the power consumption of a Base Station (BS) in a multi antenna system are provided. The method for reducing the power consumption of the BS includes identifying an amount of resources being in use for communication, determining whether to convert at least one Radio Frequency (RF) unit into a power saving mode considering the amount of resources, if converting at least one RF unit into the power saving mode, turning OFF a power supply of a power amplifier of at least one of at least two antenna paths constituting the at least one RF unit converted into the power saving mode, and increasing a gain of at least one antenna path turning ON a power supply such that a transmission Power Spectral Density (PSD) is not changed according to the power saving mode conversion.
