5 Performance assessment
37.1133GPPMulti-Standard Radio (MSR) Base Station (BS) Electromagnetic Compatibility (EMC)NR, E-UTRA, UTRA and GSM/EDGERelease 17TS
The following information shall be recorded in or annexed to the test report:
– the primary functions of the radio equipment to be tested during and after the EMC testing;
– the intended functions of the radio equipment which shall be in accordance with the documentation accompanying the equipment;
– the method to be used to verify that a communications link is established and maintained;
– the user-control functions and stored data that are required for normal operation and the method to be used to assess whether these have been lost after EMC stress;
– the ancillary equipment to be combined with the radio equipment for testing (where applicable);
– the information about ancillary equipment intended to be used with the radio equipment;
– information about the common and/or RAT-specific active RF components and other HW blocks for a communication link in MSR BS or other BS supporting more than one RAT
– information about the common and/or band-specific active RF components and other HW blocks for a communication link in BS capable of multi-band operation;
– an exhaustive list of ports, classified as either power or signal/control. Power ports shall further be classified as AC or DC power.
Performance assessment of a BS with multiple enclosures may be done separately for the BS part with the Radio digital unit and the Radio unit respectively, according to the manufacturer’s choice.
A communication link used by more than one RAT or more than one operating band, shall be assessed on all RATs and operating bands. Communication link(s) and/or radio performance parameters for the RATs and operating bands can during the test be assessed simultaneously or separately for each RAT and band, depending on the test environment capability.
5.2 Assessment of performance in Downlink
In the immunity tests, the output of the transmitter shall be connected to equipment which meets the requirements for the performance assessment of RAT and bearer used in the immunity tests according to the following:
– Throughput assessment in TS 38.101-4  in case of NR
– Throughput assessment in TS 36.101  in case of E-UTRA
– BLER assessment in TS 25.101  in case of UTRA FDD
– BLER assessment in TS 25.102  in case of UTRA TDD
– BER assessment in annex A.1 in case of GSM/EDGE
– Throughput assessment in TS 36.101  in case of NB-IoT
Power control shall be OFF during the immunity testing.
5.3 Assessment of performance in Uplink
In the immunity tests, the performance in the uplink shall be monitored at a telecommunications port(s) by using suitable test equipment according to the following:
– The value of the throughput shall be monitored in case of E-UTRA, and/or in case of NR
– The value of the BLER shall be monitored in case of UTRA FDD and UTRA TDD
– The value of the BER shall be monitored in case of GSM/EDGE (see annex A.2)
– The value of the throughput shall be monitored in case of NB-IoT
5.4 Ancillary equipment
At the manufacturer’s discretion the test may be performed on the ancillary equipment separately or on a representative configuration of the combination of radio and ancillary equipment. In each case EUT is tested against all applicable immunity and emission clauses of the present document and in each case, compliance enables the ancillary equipment to be used with different radio equipment.
