  • the resolution of the resources used for IpN measurements in frequency and time dimension are selected adaptively, e.g., by the network node 16.

  • the scheduler (e.g., via the network node 16) schedules the measurements. At the same time, the scheduler facilitates the use of MSRx feature based on the new IpN measurement configuration.
