K.1 NB-IoT Test frequencies for TRx Tests

36.521-13GPPEvolved Universal Terrestrial Radio Access (E-UTRA)Part 1: Conformance testingRadio transmission and receptionRelease 17TSUser Equipment (UE) conformance specification

Testing frequencies for all NB-IoT TRx test cases (sections 6 and 7 in TS 36.521-1) should be selected across the bands UE supports from any of the following subclauses indicated by each test case.

For transmitter test cases (section 6 in TS 36.521-1), UL frequencies should be considered on the test frequency selection algorithm described above, while DL frequencies should be used for receiver test cases (section 7 in TS 36.521-1).

Refer to TS 36.508 [7] section 8.1.3.1 for testing frequencies associated to each frequency band and each operation mode.

K.1.1 Test frequencies selection criteria 1

Among all frequency bands ranges below 1GHz supported by the UE, testing points are defined as:

– @ low range of the lowest supported band

– @ high range of the highest supported band

If the UE does not support any frequency band below 1GHz, these test points are not applicable.

Among all frequency bands ranges above 1GHz supported by the UE, testing points are defined as:

– @ low range of the lowest supported band

– @ high range of the highest supported band

If the UE does not support any frequency band above 1GHz, these test points are not applicable.

K.1.2 Test frequencies selection criteria 2

Among all frequency bands ranges below 1GHz supported by the UE, testing points are defined as:

– @ low range of the lowest supported band

– @ high range of the highest supported band

– All mid range of all supported mid bands (supported bands between lowest supported band and highest supported band below 1GHz)

If the UE does not support any frequency band below 1GHz, these test points are not applicable.

Among all frequency bands ranges above 1GHz supported by the UE, testing points are defined as:

– @ low range of the lowest supported band

– @ high range of the highest supported band

– All mid range of all supported mid bands (supported bands between lowest supported band and highest supported band above 1GHz)

If the UE does not support any frequency band above 1GHz, these test points are not applicable.

K.1.3 Test frequencies selection criteria 3

Among all frequency bands ranges supported by the UE, testing points are defined as:

– @ low range of each supported band

– @ high range of each supported band
