¿µ¹® ³»¿ë¿ä¾à This technical report presents a method for training and reasoning of a distributed artificial intelligence model that performs multi-purpose resource management optimization as a promising use case of artificial intelligence for optimizing wireless networks. In an environment where all access points (APs) of a wireless network share radio resource, different individual key performance indicators of individual APs, such as spectral efficiency (SE) and energy efficiency (EE), can be addressed at the same time. A technical method is presented to solve the multi-purpose resource allocation problem that simultaneously optimizes performance indicators with distributed computation that operates in real time. Through this manner, real-time resource management of next-generation communication applications, in particular, machine-type communication systems requiring various types of communication services is conducted.
Based on the AI/ML technologies of 3GPP and ORAN standards, this technical report discusses the training method of the distributed AI/ML model and the concept of a cooperative communication interface between wireless devices for the implementation of the model.
