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.
