RAN WG4 works on the RF aspects of UTRAN/E-UTRAN. RAN WG4 performs simulations of diverse RF system scenarios and derives the minimum requirements for transmission and reception parameters, and for channel demodulation. Once these requirements are set,the group defines the test procedures that will be used to verify them (only for BS). Requirements for other radio elements, like Repeaters, are specified in the RAN WG4 as well.

Terms of Reference

 

The latest terms of reference were approved at RAN#53
in document RP-111391.

 

Within the scope of TSG RAN, RAN WG4 is responsible for the development of specifications dealing with UTRA, Evolved UTRA, and beyond.
RAN WG4 is responsible for:

 

  • Radio specification for the Base Station and evolved Base Station, Repeater and Evolved Repeater, Terminal and evolved Terminal.
  • Base Station and evolved Base Station, Repeater and Evolved Repeater Radio Conformance test specifications
  • Base Station and evolved Base Station, Repeater and Evolved Repeater EMC specification
  • Terminal and evolved terminal EMC specification
  • Radio Link requirement specification
  • Cell selection/reselection performance requirement specifications
  • Performance requirements in support of Radio Resource Management
  • Specification of the accuracy of measurements offered by the physical layer to the upper layers Radio system scenario analysis and simulation

 

Requirements for UE and evolved UE tests as defined in TSG RAN WG5 for functions under RAN WG4 responsibility.

5G Network Infrastructure Summit

ETSI is organising its third summit on 5G, but this time the presentations will focus on the network's infrastructure and the technical solutions for the performance, reliability, energy efficiency and security that will be in the standards for the 5G system.

Georg Mayer, the TSG CT Chairman, is representing our technical leadership on the programme committee and he will also speak at the Summit, about the early prioritisation process for work on the next generation core network from 3GPP...more
