RAN WG3 is responsible for the Overall UTRAN/E-UTRAN architecture and the specification of protocols for the Iu, Iur, Iub, S1 and X2 interfaces.

Terms of Reference 

The latest terms of reference were approved at RAN#71
in document RP-160060

Within the scope of TSG RAN, RAN WG3 is responsible for the development of specifications dealing with UTRA, Evolved UTRA, and beyond, and in particular for:

  • Overall UTRAN and E-UTRAN architecture
  • 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)
  • S1 and X2 interface protocol specifications
  • M1, M2 and M3 interface protocol specifications
  • Iuh, and Iurh interface protocols specification
  • LTE Positioning Protocol A (LPPa)
