Comparison of Power Consumption Models for 5G Cellular
Power consumption models for base stations are briefly discussed as part of the development of a model for life cycle assessment. An overview of relevant base station power
This restricts the potential use of the power models, as their validity and accuracy remain unclear. Future work includes the further development of the power consumption models to form a unified evaluation framework that enables the quantification and optimization of energy consumption and energy efficiency of 5G networks.
Often referred to as the brain center, this includes: Baseband Unit (BBU): Handles baseband signal processing. Remote Radio Unit (RRU): Converts signals to radio frequencies for transmission. Active Antenna Unit (AAU): Integrates RRU and antenna for 5G-era efficiency. 2. Power Supply System
The further completion of the map of power models (Fig. 2) and systematization of their features as well as the comparison is also part of the future work. Lastly, the aspects of computing (network function virtualization) and functional split options of the RAN need to be considered for 5G networks as well.
The Björnson model presented in and exclusively considers mMIMO base stations. It is further adapted by Hossain et al. and later Peesapati et al. .
