Approved following the TSG-RAN meeting #37 in Riga, 11 - 14 September 2007
Third generation mobile 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.
The TSG Radio Access Network (TSG-R) is responsible for the UTRAN and evolved
UTRAN, including their internal structures, of systems based on 3GPP
specifications for evolved 3G and beyond.
Specifically it has a responsibility for:
• Radio aspects of Terminal Equipment and evolved Terminal Equipment and evolved
UTRAN functions (FDD & TDD), requirements and interfaces. Management of work
items placed under its responsibility.
More specifically, TSG-RAN will address the following areas of work:
• Radio Layer 1 specification;
• Radio Layer 2 specification;
• Radio Layer 3 specification;
• Iub specification (including logical O&M);
• Iur specification;
• Iu specification;
• Iuant specification;
• S1 specification including O&M aspects;
• X2 specification including O&M aspects;
• UTRAN and evolved UTRAN O&M requirements;
• Transport of implementation specific O&M between the Management System and
node B/e Node B
• Conformance test specifications for testing of all aspects of base stations
and evolved base stations;
• Specifications for radio performance and RF system aspects
• Conformance test specification for evolved UE • .
• Liaising with other TSGs, in particular TSG SA, to ensure overall
co-ordination.
• Elaborating on behalf of 3GPP the submission to ITU-R relating to the
specification of IMT advanced systems
