  The O-RAN architecture enables a more flexible and dynamic radio access
network (RAN) control by separating hardware and software components. However,
the distributed nature of the O-RAN architecture also presents several
challenges for mitigating network control conflicts that can arise between
different network elements. In this article, we identify key challenges for
conflict mitigation in O-RAN networks, including reliable conflict detection,
efficient maintenance of conflict mitigation configuration, optimal conflict
resolution logic, testing and evaluation methodologies, and limited
observability of O-RAN components. We propose solutions to these challenges,
including pre-deployment conflict mitigation, conflict detection and
resolution, and supervision and adaptation. The article concludes by
highlighting the need for ongoing research to address these challenges and
ensure effective conflict mitigation in O-RAN deployments.
