– as specified in table 7.3.5.3-1 to table 7.3.5.3-3 for E-UTRA.

– as specified in table 7.3.5.4-1 to table 7.3.5.4-3 for NR.

3) Set the Signal generator for the AWGN interfering signal at the same frequency as the wanted signal to transmit:

– as specified in table 7.3.5.1-1 for UTRA.

– as specified in table 7.3.5.2-1 for UTRA TDD 1,28Mcps operation.

– as specified in table 7.3.5.3-1 to table 7.3.5.3-3 for E-UTRA.

– as specified in table 7.3.5.1-1 to table 7.3.5.1-3 for NR.

4) Measure:

– BER according to annex C in TS 25.141 [18] for FDD UTRA.

– BER according to annex F in TS 25.142 [20] for TDD UTRA.

– Throughput according to annex E in TS 36.141 [17] for E-UTRA.

– Throughput according TS 38.141-1 [37] for NR.

In addition, for multi-band TAB connector(s), the following steps shall apply:

5) For multi-band TAB connectors and single band tests, repeat the steps above per involved band where single band test configurations and test models shall apply with no carrier activated in the other band.
