Maximum Power Reduction (MPR) (6.2.3) 3.1.3.
This chapter describes UL measurement examples where (Modulation, RB) is (QPSK, FullRB), (16QAM, PartialRB), or
(16QAM, FullRB).
[Pass/Fail evaluation limits value setting]
1. Execute PWR_AVG 20 to set the average count of power measurement to 20 times.
2. Execute TP_MPR1_LL 19.3 to set TX1 - Max. Power (QPSK/FullRB) Pass/Fail lower limit to 19.3 dBm.
3. Execute TP_MPR1_UL 25.7 to set TX1- Max. Power (QPSK/FullRB) Pass/Fail upper limit to 25.7 dBm.
4. Execute TP_MPR2_LL 19.3 to set TX1 - Max. Power (16QAM/PartialRB) Pass/Fail lower limit to 19.3 dBm.
5. Execute TP_MPR2_UL 25.7 to set TX1 - Max. Power (16QAM/PartialRB) Pass/Fail upper limit to 25.7 dBm.
6. Execute TP_MPR3_LL 18.3 to set TX1 - Max. Power (16QAM/FullRB) Pass/Fail lower limit to 18.3 dBm.
7. Execute TP_MPR3_UL 25.7 to set TX1 - Max. Power (16QAM/FullRB) Pass/Fail upper limit to 25.7 dBm.
[(QPSK, FullRB) measurements]
8. Execute TESTPRM TX_MAXPWR_Q_F to set Test Parameter to TX1 - Max. Power (QPSK/FullRB).
9. Execute SWP to measure the power.
10. Execute POWER? AVG to read the TX power measurement result.
11. Execute POWERPASS? to check that the TX power measurement Pass/Fail judgment is Pass.
[(16QAM, PartialRB) measurements]
12. Execute TESTPRM TX_MAXPWR_16_P to set Test Parameter to TX1 - Max. Power (16QAM/PartialRB).
13. Execute ULRB_POS MIN to set UL RB Position to Min (#0).
14. Execute steps 9 to 11.
[(16QAM, FullRB) measurements]
15. Execute TESTPRM TX_MAXPWR_16_F to set Test Parameter to TX1 - Max. Power (16QAM/FullRB).
16. Execute steps 9 to 11.
NOTE 1: The UL RB Position for PartialRB allocation is Min (#0).
NOTE 2: The usual Pass/Fail evaluation value is set to the Band 1 default value described in TS36.521-1.
Since the evaluation value differs according to the Band, set the evaluation value described in
TS36.521-1 Table 6.2.3.5-1 at:
 TP_MPR1_LL
 TP_MPR1_UL
 TP_MPR2_LL
 TP_MPR2_UL
 TP_MPR3_LL
 TP_MPR3_UL
For the Pass/Fail evaluation values, refer to Chapter 3.7.4 Test Parameter Limit in the operation manual.
