7.4 In-channel selectivity

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

7.4.1 Definition and applicability

In-channel selectivity (ICS) is a measure of the receiver ability to receive a wanted signal at its assigned resource block locations in the presence of an interfering signal received at a larger power spectral density. In this condition a throughput requirement shall be met for a specified reference measurement channel. The interfering signal shall be an E-UTRA signal as specified in Annex C and shall be time aligned with the wanted signal.

7.4.2 Minimum Requirement

The minimum requirement is in TS 36.104 [2] subclause 7.4.1.

7.4.3 Test purpose

The purpose of this test is to verify the BS receiver ability to suppress the IQ leakage.

7.4.4 Method of testing

7.4.4.1 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

1) Connect the test equipment as shown in Annex I.2.3.

7.4.4.2 Procedure

For each supported E-UTRA channel BW:

1) Adjust the signal generator for the wanted E-UTRA signal as specified in Table 7.4-1 for Wide Area BS, in Table 7.4-2 for Local Area BS, in Table 7.4-3 for Home BS and in Table 7.4-4 for Medium Range BS on one side of the FC.

2) Adjust the signal generator for the interfering signal as specified in Table 7.4-1 for Wide Area BS, in Table 7.4-2 for Local Area BS, in Table 7.4-3 for Home BS and in Table 7.4-4 for Medium Range BS at opposite side of the FC and adjacent to the wanted signal.

3) Measure the throughput according to Annex E.

4) Repeat the measurement with the wanted signal on the other side of the FC, and the interfering signal at opposite side of the FC and adjacent to the wanted signal.

5) Repeat the measurement for the other RX port(s).

In addition, for a multi-band capable BS, the following step shall apply:

6) For multi-band capable BS and single band tests, repeat the steps above per involved band 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.

For each supported E-UTRA channel BW with NB-IoT in-band operation:

1) Adjust the signal generator for the wanted NB-IoT signal as specified in Table 7.4-5 for Wide Area BS, in Table 7.4-7 for Local Area BS, in Table 7.4-9 for Home BS, in Table 7.4-11 for Medium Range BS with 15 kHz channel spacing and in Table 7.4-6 for Wide Area BS, in Table 7.4-8 for Local Area BS, in Table 7.4-10 for Home BS, in Table 7.4-12 for Medium Range BS with 3.75 kHz channel spacing on one side of the FC.

2) Adjust the signal generator for the interfering signal as specified in Table 7.4-5 for Wide Area BS, in Table 7.4-7 for Local Area BS, in Table 7.4-9 for Home BS, in Table 7.4-11 for Medium Range BS with 15 kHz channel spacing and in Table 7.4-6 for Wide Area BS, in Table 7.4-8 for Local Area BS, in Table 7.4-10 for Home BS, in Table 7.4-12 for Medium Range BS with 3.75 kHz spacing at opposite side of the FC.

3) Measure the throughput according to Annex E.

4) Repeat the measurement with the wanted signal on the other side of the FC, and the interfering signal at opposite side of the FC.

5) Repeat the measurement for the other RX port(s).

7.4.5 Test Requirements

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 with parameters specified in Table 7.4-1 for Wide Area BS, in Table7.4-2 for Local Area BS, in Table 7.4-3 for Home BS and in Table 7.4-4 for Medium Range BS.
