2.4.9 Uplink Power Control
This section defines parameters related to the control of the UE uplink power by the
instrument. The PRACH and initial PUSCH power are relevant during connection
setup. During an established connection the power is controlled via TPC commands.

2.4.9.1 PRACH and Initial PUSCH Power
The following parameters configure the PRACH power and the initial PUSCH power.
By default the basic settings apply (see figure 2-58 ). Only the "Open Loop Nominal
Power" is configurable. The advanced settings are not configurable and the grayed out
values indicate the used basic settings.
If you enable the advanced settings, the grayed out values become configurable.
Instead the "Open Loop Nominal Power" parameter is disabled.
