## Abstract

A network includes a user equipment, and a Radio Access Network (RAN) composed of RAN nodes and includes RAN components. An infrastructure management entity generates system information elements (SI-IEs) relative to an infrastructure layer (I-SI-IEs), and inputs them to the RAN components. The RAN components generate SI composed of SI-IEs relative to the RAN, the SI-IE is relative to an application layer (A-SI-IE), and is either configured locally by the RAN components, or received from an operations and management system entity. An I-SI-IE inputted by an infrastructure management entity, and/or information derived from one or more A-SI-IEs and/or I-SI-IEs. The RAN components are configured to transmit the generated SI to radio units (RUs) via a fronthaul interface. The one or more RUs uses the information received from the RAN to generate and transmit a radio signal comprising the SI-IEs. The user equipment receives the radio signal transmitted by the RUs.
