Power saving method using a smart antenna base station and a base station

The present invention provides a power saving method of a base station and a base station using a smart antenna, wherein the method comprises: determining a current base station corresponding to the cell in a low load state; closing direction of the transmission portion of the current cell passage all the RRU, but not Close all the channels of the receive direction of the RRU. The present invention uses only the transmission direction leisure RRU open portion of the channel system in a manner to reduce the power consumption of the RRU, effectively achieve power saving function of the base station, and less impact on communication performance.
