Abstract:

Fulfilling mobile data demands such as high-resolution (lower delay) applications, videos, IoT, videogames, virtual and augmented reality is expected to increase the amount of energy consumed by mobile networks. Massive MIMO is expected to play a key role in meeting this demand by significantly increasing the number of antennas at the base stations (BS). The growing amount of demand for mobile applications and the corresponding Radiofrequency (RF) architecture will have an impact on the energy consumed at the base station. It is known that within the mobile operators, base stations (BS) are the most energy-consuming entities and account for more than 50% of the total power consumption. To manage this energy challenge, a new metric has been introduced called “Energy-Efficiency (EE)”, measured in bits/Joule. Itis often encountered in the literature that hardware circuitry’s impact is best utterly simplified; however, at expected operating frequencies in 5G wireless systems (i.e., massive MIMO to play a key role), these effects cannot be neglected and need to be modeled properly. We further enhance this model and delivered performance simulations to analyze the EE performance under different channel gains and these hardware imperfections.

Keywords:
