3GPP Relative Power Control
Ramping up or down test pattern according to 3GPP TS 36.521, section 6.3.5.2.
Select the test pattern via "3GPP Rel. Pow. Ctrl. Pattern" and start the pattern via
the "Execute" button.
For details about the test pattern, see
●
Single Pattern, User-defined Single Pattern
A configurable TPC pattern is sent to the UE when the "Execute" button is pressed.
Before and after execution of the pattern, the power is kept constant.
A single pattern contains only one type of TPC command while a user-defined sin-
gle pattern allows you to combine different TPC commands.
●
User-defined Continuous Pattern
A configurable user-defined TPC pattern is sent to the UE continuously. If this
setup is selected, it is executed automatically without additional user action.
While this setup is selected, the relevant parameter for pattern configuration is
marked by the string "Adjusted".
●
Alter1, -1, ...
An alternating TPC pattern of plus and minus 1-dB commands is sent to the UE
continuously. If this setup is selected, it is executed automatically without additional
user action.
●
Closed Loop
The UE is commanded to the configured target power. This is done by sending
plus or minus 1-dB commands until the difference between the measured UL
power and the target power is less than 1 dB. Afterwards the power is kept con-
stant (0-dB commands).
This setup is executed automatically without additional user action. Even the mea-
surement of the uplink power is performed automatically in the background. No
additional measurement application is needed.
Depending on the current configuration, some values are grayed out. The reason is
displayed in that case, for example active PUCCH scheduling (number of RBs = 0) or
active HARQ. TPC setups for which skipping a bit is no problem, are always available
(for example max power or closed loop, in contrast to single or alternating pattern).
If you change the configuration so that the currently active setup is no longer allowed
(for example activate HARQ), the TPC setup is corrected automatically and a notice is
displayed.
Remote command:
3GPP Rel. Pow. Ctrl. Pattern
Selects the pattern to be executed for the TPC setup "3GPP Relative Power Control".
The available up and down patterns are defined in 3GPP TS 36.521, section 6.3.5.2.
