3GPP TSG RAN WG2 - Radio Layer 2 and Radio Layer 3 RR

SCOPE

The 3rd Generation Partnership Project (3GPP) is the primary body for developing technology specifications for cellular networks. It self-organises through its Working Groups coordinated by the Chairs of the Technical Specifications Groups (TSGs).

Within the scope of TSG-RAN, RAN WG2 (Radio Layer 2 and Radio Layer 3 RR)  is responsible for the development of specifications dealing with 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 as well as between relay node and eNodeB.
  • Specification of radio interface protocols common to RAN and GERAN.
  • For EUTRAN, specification of the radio interface parameters to be exchanged between eNodeBs in case of inter eNodeB handover, and between eNodeB 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.
  • For EUTRAN, specification of radio interface protocols between UE and positioning server.
  • Specification of radio measurements reported to the OAM domain and the radio interface protocols used to collect them.
