TPC Test Setup UL CM
The TPC test setup for uplink Compressed Mode (CM) activates TPC pattern for CM
testcases using UL CM trigger.
When the setup is executed, the instrument sends the power commands to the UE
according to the selected CM pattern, see
After the pattern execution, the UE is commanded to set target power again.
As precondition you defines the target power as maximum total UL power. "Maximum"
because the total power may vary during a call, even if the UL power is not changed
via TPC commands. 3GPP TS 34.121 requires output power of the UE of -36
±
9 dBm.

Rules for the Transfer of TPC Patterns
Administrable TPC patterns are transmitted via the downlink DPCH.
A pattern starts always at the beginning of a frame:
●
A new pattern following an "All 0" or "All 1" pattern starts at the beginning of the
first frame after the current frame.
