The Mobile
Broadband Standard

<<UPDATED 2018-11-15>> Mr. Juergen Hofmann (Nokia Germany / ETSI ) was re-elected as Chairman by acclamation.

Terms of reference

The terms of reference were approved at RAN#75
in document RP-170523.

Within the scope of TSG RAN, RAN WG6 is responsible for the development of specifications dealing with GSM/EDGE Radio Access Network (GERAN) and UMTS Radio Access (UTRA) aspects, and interfaces.

Specifically RAN WG6 is responsible for:

• RF aspects of GERAN,
• GERAN Radio Layer 1 specification,
• GERAN Radio Layer 2 specification,
• GERAN Radio Layer 3 RR specification,
• A interface specification, Gb interface specification,
• Internal GERAN interface specifications such as Abis, and Ater (Channel Codec Unit-Transcoder and Rate Adapter Unit),
• GERAN functionality related to the support of location services,
• Conformance test specifications for testing of all aspects of GERAN base stations,
• Specifications for GERAN radio performance and RF system aspects, and
• GERAN specific operation and maintenance specifications for the nodes in the GERAN.

RAN WG6 is also responsible for the following layer 1 related UTRA aspects: 

• Specification of the physical layer of the Uu radio Interface for UE, UTRAN, covering both FDD and TDD modes. The work includes especially: 

• • Specification of physical channel structures
  • Specification of the mapping of the transport channels onto physical channels
  • Specification of the physical layer multiplexing, and channel coding and error detection
  • Specification of the spreading and modulation
  • Specification of the physical layer procedures
  • Specification of definition of measurements and their provision by the physical layer to the upper layers
    
    
• and carries out work related to handling of the physical layer related UE capabilities and to physical layer related parameters used in UE tests developed in TSG RAN

RAN WG6 is also responsible for the following UTRA aspects:

• 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 UTRAN and GERAN
• Maintaining the specifications for the protocol used to configure UE loop back functionality for UTRAN
• Specification of radio interface parameters to be exchanged between RNCs and between RNCs and BSCs in case of SRNS relocation
• 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
• 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 UTRA functions
• Specification of radio measurements reported to the OAM domain and the radio interface protocols used to collect them
