TSG RAN WG2 Terms of Reference

Approved at 3GPP RAN#38 - Cancun, Mexico 27-30 November 2007

Within the scope of TSG-RAN, RAN WG2 is responsible for the development of specifications dealing with UTRA, Evolved UTRA, and beyond.

RAN WG2 is responsible for:

• Specification of the radio interface architecture and protocol termination
• Specification of radio interface protocols between UE and RAN,
• Specification of radio interface protocols common to RAN and GERAN e.g. PDCP
• Maintaining the specifications for the protocol used to configure UE loop back functionality   
• Specification of radio interface parameters to be exchanged between RNCs and between RNCs and BSCs in case of SRNS relocation
• For the evolved UTRAN, specification of the radio interface parameters to be exchanged between evolved NodeBs in case of inter evolved NodeB handover, and between evolved NodeB and RNC/BSC in case of inter-RAT handovers
• Stage 2 Specifications of the services offered by the physical layer to upper layers
• Specification of Cell selection and re-selection procedures
• Specification of UE capabilities for UE - RAN interface (in collaboration with RAN WG1 for Layer 1 capabilities)
• Definition of RRM strategies to be supported by RAN
• Definition of protocol methodology in RAN specifications
• Identification of the requirements for UE protocol tests to be defined by TSG RAN WG5, for new functions under RAN WG2 responsibility
