Introduction
Mobile communication networks have evolved from 1st generation to 3rd, and now, many operators are preparing to
introduce LTE. Economical and efficient deployment of base stations is one of key issues for the success of mobile
services. Operators also consider ecological aspects when renewing a system.
In general mobile radio base stations consist of a BaseBandUnit (BBU) and a Radio Frequency Unit (RFU), which
usually is a RemoteRadioHead (RRH) in a distributed base station architecture.
Current interfaces between BBU and RRH are provided in a "semi proprietary" nature, although based on industry
standards like CPRI or OBSAI. In order to gain flexibility operators are looking for distributed base station
architectures with separate BBUs and RRHs. In order to gain interoperability, BBU and RRH are interconnected via an
open BBU-RRH Interface (ORI) for flexible combination from different vendors.
ORI is about a digitized radio base station interface that establishes a connection between 'Radio Equipment Control'
(REC) and 'Radio Equipment' (RE) enabling single-hop and multi-hop topologies. Different information flows (User
Plane data, Control and Management Plane data, and Synchronization Plane data) are multiplexed over the interface.
ORI covers OSI protocol layer 1, Layer 2 up to Layer 7.
The present document aims to define a set of system and link requirements that apply to the Open Radio equipment
Interface (ORI).
