3G systems should be based on new wide band, multimode, flexible radio access. This approach will ensure that systems based on 3GPP specifications will be capable of rapid development and deployment of competitive service offerings while still enabling global roaming.
Radio Access Network
TSG Radio Access Network (TSG RAN) is responsible for the definition of the functions, requirements and interfaces of the UTRA/E-UTRA network in its two modes, FDD & TDD. More precisely: radio performance, physical layer, layer 2 and layer 3 RR specification in UTRAN/E-UTRAN; specification of the access network interfaces (Iu, Iub, Iur, S1 and X2); definition of the O&M requirements in UTRAN/E-UTRAN and conformance testing for User Equipment and Base Stations.
Terms of Reference
The latest terms of reference were approved at RAN#71
in document OP35_09.
The TSG Radio Access Network (TSG-RAN) is responsible for the GERAN, UTRAN and E-UTRAN, including their internal structures and functions, of systems for evolved GERAN, UTRAN, E-UTRAN and beyond.
Specifically it has a responsibility for:
• Radio aspects, functions, requirements and interfaces of GERAN, UTRAN (FDD & TDD) and E-UTRAN (FDD & TDD).
• Management of work items placed under its responsibility.
More specifically, TSG-RAN will address the following areas of work:
• Specification of layer 1, layer 2 and layer 3 of:
- radio interface for MS and BTS,
- radio interface for UE and Node B, and
- radio interfaces for UE, relay node and eNode B.
• Overall GERAN, UTRAN and E-UTRAN architecture, including the specification of interfaces between GERAN, UTRAN and E-UTRAN and the Core Network, and of network interfaces within GERAN, UTRAN and E-UTRAN.
• Specification of LPP between UE and positioning server for E-UTRAN, and LPPa between eNode B and positioning server.
• GERAN, UTRAN and E-UTRAN O&M requirements.
• Transport of implementation specific O&M between the Management System and Node B.
• Conformance test specifications for testing of all aspects of GERAN, UTRAN and E-UTRAN base stations and evolved base stations.
• Specifications for radio performance and RF system aspects.
• Conformance test specification and test procedures for GERAN MS and UTRAN and E-UTRAN UE.
• Liaising with other TSGs, in particular TSG SA, to ensure overall co-ordination.
• Elaborating on behalf of 3GPP the submissions to ITU-R.
