1. A wireless communication method using a plurality of antennas performed by a controller, the wireless communication method comprising:
- obtaining a target transmission power level and beam forming information;
determining at least one inactive antenna from among the plurality of antennas, based on the target transmission power level and the beam forming information; and
controlling transmission signals provided to the plurality of antennas such that transmission via the at least one inactive antenna does not occur.
