4  Control of UE/NG-RAN measurements

In this chapter the general measurement control concept of the higher layers is briefly described to provide an understanding on how L1 measurements are initiated and controlled by higher layers.
With the measurement specifications L1 provides measurement capabilities for the UE and NG-RAN. These measurements can be classified in different reported measurement types: intra-frequency, inter-frequency, inter-system, traffic volume, quality and UE internal measurements.
In the L1 measurement definitions, see chapter 5, the measurements are categorised as measurements in the UE or measurements in the NG-RAN.
