7.2 Reference sensitivity level
36.1413GPPBase Station (BS) conformance testingEvolved Universal Terrestrial Radio Access (E-UTRA)Release 17TS
7.2.1 Definition and applicability
The reference sensitivity power level PREFSENS is the minimum mean power received at the antenna connector at which a throughput requirement shall be met for a specified reference measurement channel.
The test is set up according to Annex I.2.1 and performed without interfering signal power applied to the BS antenna connector. For duplex operation, the measurement configuration principle is indicated for one duplex branch in Annex I.2.1. The reference point for signal power is at the input of the receiver (antenna connector).
7.2.2 Minimum Requirement
The minimum requirement is in TS 36.104 [2] subclause 7.2.1.
7.2.3 Test purpose
To verify that at the BS Reference sensitivity level the throughput requirement shall be met for a specified reference measurement channel.
7.2.4 Method of testing
7.2.4.1 Initial conditions
Test environment: normal; see subclause D.2
RF channels to be tested for single carrier: B, M and T; see subclause 4.7.
The following additional tests shall be performed:
a) On each of B, M and T, the test shall be performed under extreme power supply as defined in subclause D.5
NOTE: Tests under extreme power supply also test extreme temperature.
1) Connect the test equipment as shown in Annex I.2.1.
7.2.4.2 Procedure
1) a) For FDD BS start BS transmission according to E-TM 1.1 at manufacturer’s declared rated output power.
b) For NB-IoT BS start BS transmission according to N-TM at manufacturer’s declared rated output power.
2) Set the test signal mean power as specified in table 7.2-1 for E-UTRA Wide Area BS, in Table 7.2-2 for E-UTRA Local Area BS, in Table 7.2-3 for E-UTRA Home BS, in Table 7.2-4 for E-UTRA Medium Range BS, in Table 7.2-5 for NB-IoT Wide Area BS, in Table 7.2-6 for NB-IoT Local Area BS, in Table 7.2-7 for NB-IoT Home BS and in Table 7.2-8 for NB-IoT Medium Range BS, in Table 7.2-9 for subPRB allocation for Wide Area BS, in Table 7.2-10 for subPRB allocation for Local Area BS, in Table 7.2-11 for subPRB allocation for Home BS and in Table 7.2-12 for subPRB allocation for Medium Range BS.
3) Measure the throughput according to Annex E.
4) Repeat the measurement for the other RX port(s).
In addition, for a multi-band capable BS, the following step shall apply:
5) For multi-band capable BS and single band tests, repeat the steps above per involved band where single carrier test models shall apply with no carrier activated in the other band. For multi-band capable BS with separate antenna connector, the antenna connector not being under test shall be terminated.
7.2.5 Test requirement
For each measured E-UTRA carrier, the throughput shall be ≥ 95% of the maximum throughput of the reference measurement channel as specified in Annex A.1 with parameters specified in Table 7.2.5-1 for Wide Area BS, in Table 7.2.5-2 for Local Area BS, in Table 7.2.5-3 for Home BS and in Table 7.2.5-4 for Medium Range BS.
