The open radio access network (O-RAN) concept refers to the architectural design of next generation RAN that is built on the principles of openness and intelligence. This paper presents an overview of the concept of O-RAN, by analyzing its architecture and examining its main building blocks. Moreover, it highlights the significance of quality of experience (QoE) for the envisioned future wireless networks, and analyzes the importance of integrating QoE-awareness in O-RAN's design. Furthermore, it provides an analysis of the methodology of embedding artificial intelligence models in O-RAN's architecture with the form of xApps.
