3.3.2.13. Carrier leakage for CA (intra-band contiguous DL CA and UL CA) (6.5.2A.2-1)
3.3.2.13.1. MT8820C
This measurement item is not supported by the MT8820C.
Refere to Table 3.3–1.
3.3.2.13.2. MT8821C
This subsection describes an example of intra–band measurement.
Example: PCC N
RB
= 100, SCC N
RB
= 50, N
RB_alloc
= 12, Modulation = QPSK
PCC and SCC RB allocations (L
CRB
@RB
start
) are P_18@0 and S_0@0, respectively
For Intra-band measurement, Carrier Leakage Frequency Parameter must be set properly before the start of the
measurement sequence. For more information, see Annex B.2.
[Carrier Leakage Frequency Setting]
1. Execute IBEM_CLFR CFR to set Carrier Leakage Frequency to at Carrier Frequency Center.
[Measurements]
2. Execute MOD_AVG 20 to set the average count of Modulation Analysis to 20 times.
3. Execute TESTPRM TX_0DBM to set Test Parameter to TX1 – IBE/LEAK @ 0 dBm.
4. Execute ULRMC_RB_SCC1 12 to set Common Parameter – SCC-1 – UL RMC – Number of RB to 12.
(For other Configuration ID setting, set UL RMC – Number of RB and Starting RB according to TS36.521–1
Table 6.5.2A.2.1.4.1–1.)
5. Execute ULRMC_RB_SCC1 0 to set Common Parameter - SCC–1 – UL RMC – Number of RB to 0.
6. Execute SWP to measure the Modulation Analysis.
7. Execute CARRLEAK? MAX (or CARRLEAK? MAX,PCC) to read the Carrier Leakage measurement result.
8. Execute CARRLEAKPASS? (or CARRLEAKPASS? PCC) to check that the Carrier Leakage Pass/Fail judgment is
Pass.
9. Execute TESTPRM TX_M30DBM to set Test Parameter to TX1 – IBE/LEAK @ –30 dBm.
10. Execute steps 4 to 8.
11. Execute TESTPRM TX_M40DBM_Q_P to set Test Parameter toTX1 – EVM/IBE/LEAK @ –40 dBm
(QPSK/PartialRB).
12. Execute steps 4 to 8.
NOTE 1: The input level varies depending on the Carrier Frequency f under the TX1–IBE/LEAK @ 0dBm
condition.
f ≤ 3.0 GHz: 3.2 dBm ±3.2 dB
3.0 GHz < f ≤ 4.2 GHz: 3.5 dBm ±3.5 dB
NOTE 2: The input level varies depending on the Carrier Frequency f under TX1–IBE/LEAK @ –30dBm
condition.
f ≤ 3.0 GHz: –26.8 dBm ±3.2 dB
3.0 GHz < f ≤ 4.2 GHz: –26.5 dBm ± 3.5 dB
NOTE 3: The input level varies depending on the Carrier Frequency f under the TX1–EVM/IBE/LEAK @ –
40dBm condition.
f ≤ 3.0 GHz: –36.8 dBm ±3.2dB
3.0GHz < f ≤ 4.2 GHz: –36.5 dBm ±3.5dB
