D.2 E-UTRA configuration

38.521-43GPPNRPart 4: PerformanceRadio transmission and receptionRelease 17TSUser Equipment (UE) conformance specification

This clause defines the E-UTRA link settings for the test cases defined in clauses 5 and 6. The LTE link is supposed to be a functional link. The configuration defined in this clause ensures establishment of LTE link. Unless otherwise stated, ensure the UE is in state 3A-RF on the E-UTRA cell as defined in TS 36.508 [19].

Parameter

Value

Comments

Test Frequency during and after connection setup

Mid

As defined in TS 36.508 [19] for inter band test cases and as defined in TS 38.508-1 [6] clause 4.3.1 for intra band test cases, with NR SCS as per the test case for the LTE band under test

Bandwidth during and after connection setup

5 MHz (Note 1)

Supported by all LTE bands

PDSCH transmission mode and antenna config

TM1 1×2

OCNG pattern

OP.1 for FDD

OP.1 for TDD

These physical resource blocks are assigned to an arbitrary number of virtual UE‘ s with one PDSCH per virtual UE; the data transmitted over the OCNG PDSCHs shall be uncorrelated pseudo random data, which is QPSK modulated.

DL RMC

According to table A.3.2-1 in TS 36.521-1 [16] for FDD

According to table A.3.1.1-1 in TS 38.521-3 [21] for TDD

Note 1

DL RB allocation

25

Full RB allocation assuming 5 MHz ChBW. 100 RB for 20 MHz ChBW as applicable

UL Signal levels during connection setup

PUSCH Power

Attained by enabling open loop power control and setting up UL signal levels according to Annexes H.0, H.2 and H.3 of TS 36.521-1 [16]

TA adjustments

TimeAlignmentTimerDedicated IE to be set to infinity

TimeAlignmentTimerDedicated IE to be set to infinity to ensure UE doesn’t look for TA adjustments (See Table D.2-4)

CQI reports and SRS after connection setup

Disabled (See Table D.2-2 and D.2-3)

Disable periodic and aperiodic CQI reports to ensure none of these transmissions occur on the LTE uplink.

NOTE 1: If none of the UE supported EN-DC band combos support 5MHz E-UTRA carrier, configure 20 MHz channel BW.
