Test Requirement |
|
7.4.5.1 In-band selectivity and blocking, General blocking requirement |
Wanted Signal mean power = PREFSENS + x dB, where x is equal to 6 in case of E-UTRA or UTRA or NB-IoT or NR and equal to 3 in case of GSM/EDGE. Interferer signal mean power: -40 dBm. |
0 dB |
Formula: Wanted signal power + TT. Interferer signal power unchanged. |
|
7.4.5.2 In-band selectivity and blocking, General narrowband blocking requirement |
Wanted Signal mean power = PREFSENS + x dB, where x is equal to 6 in case of NR or E-UTRA or UTRA and equal to 3 in case of GSM/EDGE, and equal to the following in case of NB-IoT. For in-band NB-IoT, 1.4 MHz and 3 MHz BW: X = 11 For in-band NB-IoT, 5 MHz BW: X = 9 For in-band NB-IoT, 10MHz, 15MHz and 20MHz BW: X = 6 For guard-band NB-IoT, 5 MHz BW: X = 13 For guard-band NB-IoT, 10MHz, 15MHz and 20MHz BW: X = 6 For standalone NB-IoT, 200 kHz BW: X = 12 For NB-IoT operation in NR in-band: For 5 MHz BW:X = 9 For channel BW ≥ 10MHz: X = 6. Interferer signal mean power: -49 dBm. |
0 dB |
Formula: Wanted signal power + TT. Interferer signal power unchanged. |
|
7.4.5.5 In-band selectivity and blocking, Additional BC3 requirement |
Wanted Signal mean power = PREFSENS + x dB, where x is equal to 6 in case of NR or E-UTRA or UTRA [or NB-IoT]. Interferer signal mean power: -40 dBm. |
0 dB |
Formula: Wanted signal power + TT. Interferer signal power unchanged. |
|
7.5.5.1 Out-of-band blocking, General requirement |
Wanted Signal mean power = PREFSENS + x dB, where x is equal to 6 in case of NR or E-UTRA or UTRA or NB-IoT and equal to 3 in case of GSM/EDGE. Interferer signal mean power: -15 dBm. |
0 dB |
Formula: Wanted signal power + TT. Interferer signal power unchanged. |
|
7.5.5.2 Out-of-band blocking, Co-location |
Wanted Signal mean power = PREFSENS + x dB, where x is equal to 6 in case of NR or E-UTRA or UTRA or NB-IoT and equal to 3 in case of GSM/EDGE. Interferer signal mean power: +16 dBm. |
0 dB |
Formula: Wanted signal power + TT. Interferer signal power unchanged. |
|
7.6.5 Receiver spurious emissions |
Maximum level defined in Tables 7.6.5.1-1 and 7.6.5.2-1 of TS 37.104 [2]. |
0 dB |
Formula: Maximum level + TT |
|
7.7.5.1 Receiver intermodulation, General requirement |
Wanted Signal mean power = PREFSENS + x dB, where x is equal to 6 in case of NR or E-UTRA or UTRA or NB-IoT and equal to 3 in case of GSM/EDGE. Interferer signal mean power: -48 dBm. |
0 dB |
Formula: Wanted signal mean power + TT. CW interferer signal power unchanged. Modulated interferer signal power unchanged. |
|
7.7.5.2 Receiver intermodulation, General narrowband requirement |
Wanted Signal mean power = PREFSENS + x dB, where x is equal to 6 in case of NR or E-UTRA or UTRA or NB-IoT and equal to 3 in case of GSM/EDGE. Interferer signal mean power: -52 dBm. |
0 dB |
Formula: Wanted signal mean power + TT. CW interferer signal power unchanged. Modulated interferer signal power unchanged. |
