8.6 Performance requirements for subslot-PUSCH

36.1413GPPBase Station (BS) conformance testingEvolved Universal Terrestrial Radio Access (E-UTRA)Release 17TS

8.6.1 Definition and applicability

The performance requirement of subslot-PUSCH is determined by a minimum required throughput for a given SNR. The required throughput is expressed as a fraction of maximum throughput for the FRCs listed in Annex A. The performance requirements assume HARQ re-transmissions.

8.6.2 Minimum Requirement

The minimum requirement is in TS 36.104 [2] subclause 8.6.

8.6.3 Test Purpose

The test shall verify the receiver’s ability to achieve throughput under multipath fading propagation conditions for a given SNR.

8.6.4 Method of test

8.6.4.1 Initial Conditions

Test environment: Normal, see subclause D.2.

RF channels to be tested: M; see subclause 4.7.

1) Connect the BS tester generating the wanted signal, multipath fading simulators and AWGN generators to all BS antenna connectors for diversity reception via a combining network as shown in Annex I.3.2.

8.6.4.2 Procedure

1) Adjust the AWGN generator, according to the channel bandwidth, defined in Table 8.6.4.2-1.

2) The characteristics of the wanted signal shall be configured according to the corresponding UL reference measurement channel defined in Annex A.23 and the test parameters in Table 8.6.4.2-2.

3) The multipath fading emulators shall be configured according to the corresponding channel model defined in Annex B.

4) Adjust the equipment so that required SNR specified in Table 8.6.5-1 to 8.6.5-4 is achieved at the BS input.

5) For each of the reference channels in Table 8.6.5-1 to 8.6.5-4 applicable for the base station, measure the throughput, according to Annex E.

8.6.5 Test Requirement

The throughput shall be equal to or larger than the fraction of maximum throughput stated in the Tables 8.6.5-1 to 8.6.5-4 at the given SNR for 1Tx
