<<UPDATED 2019-11-20>> Dr. Xiang (Steven) Chen (Futurewei Technologies, ETSI) elected new RAN WG4 Chairman.
<<UPDATED 2019-08-28>> Mr. Haijie Qiu (Samsung Electronics Co., Ltd / TTA) and Mr. Andrey Chervyakov (Intel / ATIS) were elected new RAN WG4 Vice Chairmen during RAN WG4#92.
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.
