Data Radio Network with Adaptive Hardware and AI Optimization to reduce Energy Consumption


In the innovation competition “Electronics for energy-saving information and communication technology”, DAKORE competed with nine other teams from research institutions and universities for the solution idea with the greatest leverage effect for sustainable digitalization. As one of three winning concepts, DAKORE impressed with innovations in electronics with significant energy and greenhouse gas savings potential and good industrial implementability in socially important application fields of information and communication technology. The DAKORE team is now further developing its solutions in the second phase with industrial partners and advancing the technology maturity level.

Goals and Approach

In the DAKORE project, research is being conducted on reduced energy consumption of public and private 5G mobile networks. To this end, the use of fast-switching power amplifiers as well as artificial intelligence (AI) methods for energy-efficient control of base station transmit power is being considered. Adaptively changing cell ranges require radio resource management (RRM) controls such as handover decisions or adding frequency bands for carrier aggregation (CA). A special focus is put on open interfaces and components according to the ORAN architecture.

Energy saving in 5G networks

Analysis of 5G protocol flows

brown-iposs uses data analysis of 5G protocol flows to ensure that user requirements and Quality of Service (QoS) are met despite the reduction of energy consumption. The aim is to detect possible misconfigurations, such as the emergence of coverage gaps, as early as possible. The analysis requires network data from live operation, which can be provided, for example, by integrating MDT interfaces and xApps/rApps.
