- Synchronisation in UTRAN and E-UTRAN
- Stage 2 work of Work Items allocated by TSG RAN to RAN WG3
- UTRAN and E-UTRAN O&M requirements
- Iu interface protocol specifications, i.e. access stratum protocols over the Iu reference point
- Iur and Iub interface protocol specifications
- Iupc interface protocol specifications
- Iubc interface protocol specifications
- Transport of implementation specific O&M between the Management System and Node B
- Application of the RANAP on the E-interface
- Iu-ant interface protocol specifications (RF-parts of the layer 1 specification are under the responsibility of RAN4)
- Parts of Iu and Iur protocols common to GERAN and UTRAN (Iu-g and Iur-g)
