4 Test coverage analysis
4.1 Test point selection in Additional Maximum Power
Reduction (A-MPR) test cases
When deriving test points for these test cases the calculation of maximum output power backoff and determination of
possible worst cases for out-of-band emissions are non-trivial and therefore require an analysis which is documented
here.
4.1.1 A-MPR test case for single carrier
This section contains information on test point selection for test case 6.2.4 in [2], Additional Maximum Power
Reduction (A-MPR).
Test points in this test were added in the past, and no selection information is therefore available prior the NS values in
table 4.1.1-1.
Selection of test points should include some possible worst combinations based on the A-MPR characteristics specified
for each NS value and these shall be selected so that they match with corresponding spectrum emission requirements
test points. The number of test points should be realistic.

The analyses for UE category M1 are performed per NS-value in table 4.1.1-2. The general principles for selection of
test points are:
- For Additional spurious emissions, requirements are the same for all bandwidths. Since channel bandwidth is not
judged to have any impact on the UE transmit signal for category M1, only one bandwidth needs to be tested.
The lowest bandwidth with emissions requirement has lowest guard band and is therefore the most stringent.
- For NS-values with Additional SEM requirement and without any allowed A-MPR, same test points as in SEM
test case 6.6.2.1EA can be used.
- For NS-values with Additional Spurious requirement and without any allowed A-MPR, same test points as in
spurious test case 6.6.3EA.1 can be used
- For Additional SEM, test frequency is selected as in SEM test case.
- For Additional spurious emissions, test frequency selection depends on if protected range is above or below the
UE transmit signal in frequency. If protected range is in higher frequency High frequency is selected, if lower
frequency Low range is selected.

4.1.2 A-MPR test case for intra-band contiguous UL CA
This section contains information on test point selection for test case 6.2.4A.1 in [2], Additional Maximum Power
Reduction (A-MPR) for CA (intra-band contiguous DL CA and UL CA).
The analyses are performed per NS-value and are stored as zip-files as defined in annex A.
4.1.3 A-MPR test case for inter-band UL CA
This section contains information on test point selection for test case 6.2.4A.2 in [2], Additional Maximum Power
Reduction (A-MPR) for CA (inter-band DL CA and UL CA).
TS 36.101 [3] specifies band dependent NS-values, which in the inter-band UL CA test cases become a combination of
two NS-values. Testing all possible combinations would lead to too excessive testing and the combinations that are
realistic should therefore be prioritized. This selection is documented in table 4.1.3-1.

The analyses are performed per NS-value and are stored as zip-files as defined in annex A. The general principle for
selection of test points is:
- Test the minimum MPR + A-MPR value
- Test the maximum MPR + A-MPR value
- Test the maximum unbalanced total power backoff among CCs (max P difference).
cmaxc
The analyses are done for QPSK/16QAM test cases. For 64QAM test cases no analysis is made due to that it follows
the same selection principle.
4.2 Test frequency and bandwidth selection in Reference
sensitivity test cases
The determination of test frequency and channel bandwidths are made considering test time, possible worst cases and
operator deployments. This is non-trivial and requires an analysis which is documented here.
4.2.1 Reference sensitivity level for single carrier
This section contains information on test point selection for test case 7.3 in [2], Reference sensitivity level
Test points in this test were added in the past, and no selection information is therefore available.
4.2.2 Reference sensitivity level for intra-band contiguous CA
This section contains information on test point selection for test cases 7.3A.1 - Reference sensitivity level for CA (intra-
band contiguous DL CA and UL CA) and 7.3A.2 - Reference sensitivity level for CA (intra-band contiguous DL CA
without UL CA).
In this test case, there are no CA configuration specific test points. The general rule of Low, High test frequency and
Lowest N , Highest N is chosen for any CA configuration.

4.2.3 Reference sensitivity level for inter-band CA
This section contains information on test point selection for test case 7.3A.3 - Reference sensitivity level for CA (inter-
band DL CA without UL CA)
In this test case, there are default test points to be used unless CA configuration specific test points are over-ruling in
table 4.2.3-1. The default rule of Mid test frequency and Highest N is chosen for any CA configuration.

4.2.4 Reference sensitivity level for intra-band non-contiguous CA
This section contains information on test point selection for test case 7.3A.4 Reference sensitivity level for CA (intra-

Testpoint choice is based on the Table 7.3A.0-3. Only largest PCC BW + largest SCC BW and largest PCC BW +
smallest SCC BW are tested. All corner cases VS W specified for those 2 BW combinations in the Table 7.3A.0-3 are
gap
tested, larger W being considered worse. PCC is allocated to the upper carrier, unless DL Band is below UL Band and
gap
wider operating band width than UL. Most testpoint IDs for FDD bands have to be tested twice, once with RB
allocation applicable to PCC REFSENS test, which is the standard single carrier RB allocation, and once with RB
Allocation applicable to SCC REFSENS test, as per Table 7.3A.0-3.
4.2.5 Reference sensitivity level for 3DL CA
This section contains information on test point selection for test case 7.3A.5 Reference sensitivity level for 3DL CA.
In the applicability conditions in TS 36.521-2 [4] it is defined that if the 3DL test is performed, testing of some fallback
cases can be skipped , specifically:
- 2DL fallback 3DL/1UL -> 2DL/1UL: Test of fallback can be skipped in many cases. Analysis supplied per CA
configuration later in this clause.
- 2DL fallback 3DL/2UL -> 2DL/2UL: It is FFS if fallback need to be tested
- 1UL fallback 3DL/2UL -> 3DL/1UL: Test of fallback is required due to different minimum requirements.
This implies that the test point analysis described later in this section currently only considers 1UL.4.2.5.1 Intra-band
In this case, there are default test points to be used unless CA configuration specific test points are over-ruling. The
default rule of Low and High test frequency, Lowest and Highest N is chosen for any CA configuration.

Editor’s note: The specific test points for reference sensitivity level and 3DL CA Intra-band are under investigation.
4.2.5.2 Inter-band
In this case, there are default test points to be used unless CA configuration specific test points are over-ruling in table
4.2.5.2-1. The default rule of Mid test frequency and Highest N is chosen for any CA configuration. For CA
RB_agg
configurations where default test points are used and 2DL fallback cases also use default test points there is no need for
justification in Table 4.2.5.2-1.
Selection of test points should include some possible worst combinations and these can be based on operator preference
in case of the CA configuration is operator specific. The number of test points should not exceed the total number of the
maximum number of the test points to cover fallback of 2DL CA case.
