RAN1 - Radio Layer 1 (Physical layer)

<<NEW 2021-10-15>> Dr. David Mazzarese (Huawei Technologies France / ETSI) elected new Vice Chair of RAN WG1.

Within the 3GPP Technical Specification Group Radio Access Network (TSG RAN), 3GPP TSG RAN WG1 (RAN1) is responsible for the development of specifications dealing with Evolved UTRA, 5G NR, and beyond.

RAN1 is responsible for specification of the physical layer of the radio Interfaces for UE, Evolved UTRAN, NG-RAN, and beyond. The work in RAN1 includes especially:

  • Specification of physical channels and modulation
  • Specification of physical layer multiplexing, channel coding and error detection
  • Specification of physical layer procedures (both control and data)
  • Specification of definition of measurements and their provision by the physical layer to the upper layers

RAN1 also specifies handling of physical layer related UE capabilities and parameters used in device tests.
