scope:

This Recommendation provides requirements for energy saving management of a fifth generation (5G) radio access network (RAN) system with artificial intelligence (AI). This Recommendation explains the requirements of the use of AI technology to achieve energy saving management for communication units and virtualized hardware resources of a 5G RAN system, via an element management system (EMS) and open interfaces provided by vendors, from the operation support system (OSS) level. In addition, this Recommendation includes process recommendations for sending intelligent energy saving strategies from OSS to EMS and then to wireless equipment. This Recommendation covers the following aspects of energy saving management of a 5G RAN system with AI:

1) functional requirements;

2) use cases.

Requirements for energy saving control directly at the equipment level, requirements for generating energy saving strategies directly at the radio base station, energy saving requirements for non-communication units such as air conditioning refrigeration and hardware material design lie outside the scope of this Recommendation.
