<<UPDATED 2019-08-26>> Dr. Wanshi Chen (Qualcomm Incorporated / ATIS) re-elected Chairman (for a 2nd term), and Dr. Younsun Kim (Samsung Electronics Co., Ltd / TTA) re-elected Vice Chairman (for a 2nd term) by acclamation during RAN WG1#98 in August 2019.
RAN WG1 (Radio layer 1) is responsible for the specification of the physical layer of the radio Interface for UE, UTRAN, Evolved UTRAN, and beyond; covering both FDD and TDD modes of the radio interface.
Terms of reference
The latest terms of reference were approved at RAN#75
in document RP-170521.
Within the scope of TSG-RAN, RAN WG1 is responsible for the development of specifications dealing with Evolved UTRA, and beyond. RAN WG1 is responsible for specification of the physical layer of the Uu radio Interface for UE, Evolved UTRAN, and beyond, covering both FDD and TDD modes, as well as the physical layer of the Un Interface for Relay Nodes. The work in RAN WG1 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
RAN WG1 also 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.
