Summary:
The use of massive multiple-input multiple-output (m-MIMO) systems has been considered as one of key technologies in advanced wireless communication systems. However, it may need to employ an energy-efficient transmission technique. The energy efficiency can be improved by using a minimal number of transmit antennas enough to provide desired performance. However, it may require large computational complexity to optimally schedule a set of transmit antennas. In this paper, we consider minimal use of m-MIMO antennas with power control without large computational complexity. We determine the number of transmit antennas and the corresponding antenna subset by exploiting average channel information. We also adjust the transmit power and the spatial multiplexing order to provide desired performance. Finally, we verify the proposed scheme by computer simulation.
