Introduction Mobile communication networks have evolved from 1stgeneration to 3rd, and now, many operators are preparing to introduce LTE. Economical and efficient deployment o

18、f 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 distrib

19、uted 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 o

20、rder to gain interoperability, BBU and RRH are interconnected via an open BBU-RRH Interface (ORI) for flexible combination from different vendors. ETSI ETSI GS ORI 001 V4.1.1 (2014-10)5ORI is about a digitized radio base station interface that establishes a connection between “Radio Equipment Contro

21、l“ (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 d

22、ocument aims to define a set of system and link requirements that apply to the Open Radio equipment Interface (ORI). ETSI ETSI GS ORI 001 V4.1.1 (2014-10)61 Scope ETSI Group Specifications (GS) are deliverables produced by Industry Specification Groups (ISG). GSs are written with the style of a Tech

23、nical 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

24、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. 2 References References are either specific (identified by date of publication and/or e

37、4.1.1 (2014-10)114.1.2 Specific ORI node requirements on ORI links and ORI ports In support of the topology options as specified for the present release of ORI, the following is required of the RE and REC: A hop shall support at least one active link. As per the single-hop topologies defined in clau

38、se 4.1.1 it is assumed REC ports are only master ports and RE ports are only slave ports. As per the single-REC multi-hop topologies defined in clause 4.1.1, it is assumed that REC ports are only master ports and each RE port may take a master port role or a slave port role within the constraints de

39、fined below. The REC shall manage which ORI ports act as a master port in the RE (within the REs ORI port role capabilities). The following requirements shall then apply: The RE without the capability to be a networking RE shall support 1 to 255 ORI ports. The RE with the capability to be a networki

40、ng RE shall support 2 to 255 ORI ports, and shall support the simultaneous configuration of at least one ORI port as a master port and at least one other ORI port as a slave port. The REC shall support 1 to 255 ORI ports. All ORI Links terminated by an ORI port in slave role at the RE shall have the

41、ir timing generated by the same timing source. NOTE: Further restrictions may be needed for multi-REC topologies in the future. In order to support single-REC multi-hop topologies, the RE acting as a networking RE is expected to support the following: At least the simplified solution for networking,

42、 described in section 6.3 of 1. The forwarding of all the SAPs defined in 1 through the unit between relevant master and slave ports, The networking RE shall not forward SAPs defined in 1 from one slave port to another slave port, e.g. in ring topology. The forwarding of the contents of the control

43、words defined within the “ORI reserved field“, the “vendor-specific area“ between the relevant master and slave ports. Given that the RE is only required to terminate one active link at any one time, in the ring topology a break in the ring affecting the routeing of the active link would cause one o

44、r more REs to require C E-UTRA-FDD 6; E-UTRA-TDD 6; GSM 12. 3GPP releases and versions relevant to the above radio standards are specified in 1, section 3.1. Multiplexing between any combination of UTRA-FDD, E-UTRA-FDD, and GSM on an ORI link shall also be supported. 4.2.2 Specific ORI node requirem

45、ents In support of the technology options as specified for the present release of ORI, the following is required of the RE and REC: The RE/REC shall support at least one of UTRA-FDD, E-UTRA-FDD, E-UTRA-TDD, or GSM, and may optionally support multiplexing between any combination of UTRA-FDD, E-UTRA-F

46、DD, and GSM on the ORI Link. The REC and RE shall support the functional separation of radio functionality as described in: - Table 1 in 1 for support of UTRA - Table 1A in 1 in support of E-UTRA - Table 1AA in 1 in support of GSM.

47、.1 Compliance with CPRI 4.3.1.1 System requirements The CPRI specification as specified in 1 shall be the baseline for the ORI Low Layers specification 2. In line with that, the ORI shall be compliant with all of the requirements in 1 for the applicable topologies and radio standards as specified fo

48、r the present release of ORI. Furthermore, in order to make the ORI specification fully inter-operable, it may be necessary to restrict the number of options defined in 1 for usage within ORI. Such restrictions shall be described in the ORI specifications. 4.3.1.2 Specific ORI node requirements The

49、RE/REC compliant to the ORI specifications shall: be fully compliant to CPRI, as defined in section 5.2 of 1; support mandatory requirements defined within ORI that are defined as options within CPRI; support mandatory requirements defined within ORI on all layers (specified in the present document, as well as 2 and 7) that do not refer to functionality in CPRI specifications. 4.3.2 C&M functionality 4.3.2.1 System requirements The following aspects shall be supported
