- Abstract
- Considering required features for beyond-5G wireless communication, such as higher spectral efficiency and energy efficiency, cell-free massive MIMO(mMIMO) is one of the promising technologies. In this paper, we propose an Access Point(AP) Switch ON/OFF (ASO) scheme in cell-free mmWave mMIMO systems for higher energy efficiency, which switch on/off APs based on the order determined by the importance of APs within the systems. Numerical results show that the proposed scheme improves the energy efficiency performance of cell-free mmWave mMIMO systems compared to the conventional schemes.
