4 Test conditions
37.1143GPPActive Antenna System (AAS) Base Station (BS) Electromagnetic Compatibility (EMC)Release 17TS
The equipment shall be tested in normal test environment defined in base station conformance testing specification TS 37.145-1 [3], or TS 37.145-2 [10]. The test conditions shall be recorded in the test report.
For an AAS BS supporting more than one RAT, tests shall be performed with RATs activated according to the test configurations in subclause 4.4. Tests shall be performed relating to each type of port and RIB, and need not be repeated for each RAT if operating RATs are assessed simultaneously during the test.
For AAS BS supporting only single RAT operation only, tests relating to the antenna port(s) and RIBs shall be performed for each supported RAT.
For AAS BS capable of multi-band operation, the requirements in the present document apply for each supported operating band unless otherwise stated. Operating bands and RATs shall be activated according to the respective test configurations in TS 25.113 [5], TS 36.113 [6], TS 37.113 [4], or TS 38.113 [30]. Tests shall be performed relating to each type of port and RIB, and all RATs per band shall be assessed during the tests.
Requirements apply only for the declared operating band and corresponding Band Categories as per CSA and/or RCSA capability sets and manufacturer’s declarations of the AAS BS in TS 37.145-1 [3] and TS 37.145-2 [10].
The manufacturer shall declare the supported capability set(s) according to TS 37.145-1 [3] and TS 37.145-2 [10]. Tests performed on an AAS BS according to a declared capability set(s) cover all single RAT and multi-RAT configurations included in the declared capability set.
NOTE 1: TAB connector capability sets (CSA) for hybrid AAS BS are defined in TS 37.145-1 [3] and declared in D6.12 declaration.
NOTE 2: Radiated capability sets (RCSA) for hybrid AAS BS and OTA AAS BS are defined in TS 37.145-2 [10] and declared by D9.25 declaration.
Where the hybrid AAS BS has multiple TAB connectors which are declared to be equivalent then it is sufficient to perform EMC tests on a single representative TAB connector. For the definition of the TAB connector equivalence declaration (D6.70), refer to TS 37.145-1 [3].
EMC test shall not be performed with the AAS BS antenna array radiating, all TAB connectors shall be disconnected from the radio distribution network (RDN)/antenna array as specified in TS 37.105 [2] and terminated in an appropriate load impedance. For the description of the general AAS BS radio architecture and relations between the RDN/antenna array and the Transceiver Array Boundary, refer to TS 37.105 [2].
Depending on RAT capability sets supported by the AAS BS, the following test conditions shall be referred and applied for the BS test configurations:
– For AAS BS in single RAT UTRA operation the test conditions from TS 25.113 [5] apply.
– For AAS BS in single RAT E-UTRA operation the test conditions from TS 36.113 [6] apply.
– For AAS BS in single RAT NR operation the test conditions from TS 38.113 [30] apply.
– For AAS BS in MSR operation the test conditions from TS 37.113 [4] apply.
Whenever ports are considered for the emissions and immunity testing in the referred TS 25.113 [5], TS 36.113 [6] and TS 37.113 [4] specifications, special considerations shall be taken to test conditions specification for OTA AAS BS due to lack of antenna ports.
NOTE 3: The receiver exclusion bands defined in E-UTRA and MSR specifications for Band 46 operation are not applicable for AAS BS, as the Band 46 operation is not supported by AAS BS.
NOTE 4: The NB-IoT operation is not supported by AAS BS.
4.1 Exclusion bands
4.1.1 Transmitter exclusion band
The transmitter exclusion band for BS is the frequency range over which no tests of radiated immunity of a transmitter are made. The transmitter exclusion band only applies to OTA AAS BS.
The transmitter exclusion band is defined as:
FDL,low – ΔfOBUE<f < FDL,high + ΔfOBUE
Where:
The value of ΔfOBUE, FUL_low and FUL_high are defined for each operating band for NR, E-UTRA, UTRA in TS 37.105 [2].
NOTE: For BS capable of multi-band operation, the frequency ranges relating to the RF bandwidths of all supported bands apply.
4.1.2 Receiver exclusion band
An exclusion band is a band of frequencies over which no tests of radiated immunity are made.
In case the spatial exclusion (as discussed in subclause 9.2.2 and depicted in figure 9.2.2-1) is used during the EMC RI testing, the receiver exclusion band for OTA AAS BS is defined as:
FUL_low – ΔfOOB < f < FUL_high + ΔfOOB
Where:
– Values of FUL_low and FUL_high are defined for each operating band in TS 37.104 [33].
– The values of ΔfOOB are defined in table 4.1.2-1.

In case the spatial exclusion zone (as discussed in subclause 9.2.2 and depicted in figure 9.2.2-1) is not used during the EMC RI testing, the receiver exclusion band for OTA AAS BS and BS type 1-O is defined as:
FUL_low – ΔfRIexclusion < f < FUL_high + ΔfRIexclusion
Where the values of ΔfRIexclusion are defined in table 4.1.2-2.
