IPRs essential or potentially essential to the present document may have been declared to ETSI. The information
pertaining to these essential IPRs, if any, is publicly available for ETSI members and non-members, and can be found
in ETSI SR 000 314: "Intellectual Property Rights (IPRs); Essential, or potentially Essential, IPRs notified to ETSI in
respect of ETSI standards", which is available from the ETSI Secretariat. Latest updates are available on the ETSI Web
server (http://ipr.etsi.org).
Pursuant to the ETSI IPR Policy, no investigation, including IPR searches, has been carried out by ETSI. No guarantee
can be given as to the existence of other IPRs not referenced in ETSI SR 000 314 (or the updates on the ETSI Web

Foreword
This Group Specification (GS) has been produced by ETSI Industry Specification Group (ISG) Open Radio equipment
Interface (ORI).
The contents of the present document are subject to continuing work within the ISG. Should the ISG modify the
contents of the present document, it will be re-released by the ISG with an identifying change of release date and an
increase in version number as follows:
Version x.y.z
where:
x the first digit indicates the release number of ORI specification group starting from Release 1.
y the second digit is incremented for all changes of substance, i.e. technical enhancements, corrections,
updates, etc.
z the third digit is incremented when editorial only changes have been incorporated in the document.
Modal verbs terminology
In the present document "shall", "shall not", "should", "should not", "may", "may not", "need", "need not", "will",
"will not", "can" and "cannot" are to be interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms
for the expression of provisions).
"must" and "must not" are NOT allowed in ETSI deliverables except when used in direct citation.
Introduction
st rd
Mobile communication networks have evolved from 1 generation to 3 , 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 BaseBand Unit (BBU) and a Radio Frequency Unit (RFU), which
usually is a Remote Radio Head (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).

1 Scope
ETSI Group Specifications (GS) are deliverables produced by Industry Specification Groups (ISG). GSs are written
with the style of a Technical Specification (TS), and represent the sole view of the ISG members.
The present document describes system-level requirements that apply to the Open Radio equipment Interface (ORI) and
ORI nodes for Release 4.
NOTE: Requirements comply with CPRI specification of CPRI forum [1] and focuses on the following 3GPP
radio access technologies namely UTRA-FDD [3], [4] and [5], E-UTRA-FDD [6], E-UTRA-TDD [6] and
GSM [12]. Multiplexing between any combination of UTRA-FDD, E-UTRA-FDD, and GSM on an ORI
link is also considered.
