7.3B.4 EIS Spherical Coverage for Inter-band EN-DC including FR2 (1 NR CC)

38.521-33GPPNRPart 3: Range 1 and Range 2 Interworking operation with other radiosRadio transmission and receptionRelease 17TSUser Equipment (UE) conformance specification

Editor’s note: The following aspects are either missing or not yet determined:

– Measurement Uncertainties and Test Tolerances are FFS for power class 1, 2 and 4.

7.3B.4.1 Test purpose

Same test purpose as in clause 7.3.4.1 in TS 38.521-2 [9] for the NR carrier.

7.3B.4.2 Test applicability

This test case applies to all types of E-UTRA UE release 15 and forward, supporting inter-band EN-DC including FR2 with 1 NR DL CC.

7.3B.4.3 Minimum conformance requirements

Same minimum conformance requirements as in clause 7.3.4.3 in TS 38.521-2 [9] for the NR carrier.

No exception requirements applicable to NR or E-UTRA. LTE anchor agnostic approach is applied.

The normative reference for this requirement is TS 38.101-2 [9] clause 7.3.4.

7.3B.4.4 Test description

7.3B.4.4.1 Initial conditions

Same test description as in clause 7.3.4.4 in TS 38.521-2 [9] for the NR carrier with the following exception:

The initial test configurations for E-UTRA band consist of environmental conditions, test frequencies, and channel bandwidths based on E-UTRA bands specified in Table 4.6-1. For Initial conditions as in clause 7.3.4.4.1 in TS 38.521-2 [9], the following steps will be added to configure E-UTRA component:

2.1. The parameter settings for E-UTRA cell are set up according to TS 36.508 [11] clause 4.4.3.

3.1. The E-UTRA downlink signal level, uplink signal level are set according to Table 4.7-1 and propagation conditions are set according to Annex B.0 of TS 36.521-1 [10].

Step 6 of Initial conditions as in clause 7.3.4.4.1 in TS 38.521-2 [9] is replaced by:

6. Ensure the UE is in state RRC_CONNECTED with generic procedure parameters Connectivity EN-DC, DC bearer MCG and SCG, Connected without release On according to TS 38.508-1 [6] clause 4.5.

Same test procedure as in clause 7.3.4.4.2 in TS 38.521-2 [9] with the following steps added for E-UTRA component:

1.1 On the E-UTRA carrier, disable periodic and aperiodic CQI reports, disable SRS, set TimeAlignmentTimerDedicated IE to infinity and disable downlink and uplink scheduling, all as per Table 4.7-1 under clause 4.7.

7.3B.4.5 Test requirement

Same test requirement as in clause 7.3.4.5 in TS 38.521-2 [9] for the NR carrier.
