Toward Next Generation Open Radio Access Network--What O-RAN Can and Cannot Do!

Understand

The open radio access network (O-RAN) describes an industry-driven open architecture and interfaces for building next generation RANs with artificial intelligence (AI) controllers.

• We circulated a survey among researchers, developers, and practitioners to gather their perspectives on O-RAN as a framework for 6G wireless research and development (R&D).
• The majority responded in favor of O-RAN and identified R&D of interest to them.
• Motivated by these responses, this paper identifies the limitations of the current O-RAN specifications and the technologies for overcoming them.
