For V2X operation, REFSENS requirements defined in TS 38.101-1 [2] and TS 36.101 [4] apply to all downlink bands of V2X configurations listed in clause 5.5E, unless sensitivity degradation exception is allowed in this clause of this specification, clause 7.3E in TS 38.101-1 [2] or clause 7.3.1G in TS 36.101 [4].

7.3E.2 Reference sensitivity for V2X

7.3E.2.1 Intra-band contiguous V2X

For intra-band contiguous V2X listed in Table 5.5E.2-1, the each REFSENS requirements specified in clause 7.3.1G of TS 36.101 [4] and clause 7.3E.2 of TS 38.101-1 [2] apply when all SL reception CCs are activated at same time.

For intra-band non-contiguous V2X listed in Table 5.5E.3-1, the each REFSENS requirements specified in clause 7.3.1G of TS 36.101 [4] and clause 7.3E.2 of TS 38.101-1 [2] apply when all SL reception CCs are activated at same time.

7.3E.2.3 Inter-band V2X con-current operation

7.3E.2.3.0 General

When UE is configured for NR V2X reception on V2X carrier con-current with E-UTRA uplink and downlink, NR V2X sidelink throughput for the carrier shall be ≥ 95% of the maximum throughput of the reference measurement channels as specified in Annexes A.7.2 with parameters specified in table 7.3E.2-1 and 7.3E.2-2 in TS 38.101-1. Also the E-UTRA downlink throughput shall be ≥ 95% of the maximum throughput of the reference measurement channels as specified in Annexes A.3 with parameters specified in Table 7.3.1-1 and Table 7.3.1-2 in TS 36.101.

When UE is configured for E-UTRA V2X reception on V2X carrier con-current with NR uplink and downlink, E-UTRA V2X sidelink throughput for the carrier shall be ≥ 95% of the maximum throughput of the reference measurement channels as specified in Annexes A.8.2 with parameters specified in Table 7.3.1G-1 in TS 36.101. Also the NR downlink throughput shall be ≥ 95% of the maximum throughput of the reference measurement channels as specified in Annexes A.2.2.2, A3.2 and A.3.3 with parameters specified in Table 7.3.2-1a, Table 7.3.2-1b and Table 7.3.2-2 in TS 38.101-1.

The reference sensitivity is defined to be met with all downlink component carriers active. The REFSENS of Uu downlink and PC5 sidelink will be tested at the same time.

Table 7.3E.2.3.0-1: Void

Table 7.3E.2.3.0-2 is specified the additional Rx insertion loss according to different RF architecture with DC/CA UE with same band combinations to reduce the self interference problem based on specific self desense analysis according to specific NR V2X inter-band con-current operation.

Table 7.3E.2.3.0-2: ΔR_IB,V2X (two bands)

V2X inter-band con-current band Combination	E-UTRA or NR Band	ΔR_IB,V2X [dB]
V2X_20_n38	20	0.0¹
V2X_n79-47	n79	TBD
V2X_n79-47	47	TBD
Note 1: The ΔR_IB,V2Xis applied on top of ΔR_IB,c of DC_20_n38 UE that is considered harmonic trap filter to reduce 3^rd harmonic impact from Band 20.

7.3E.2.3.1 Reference sensitivity exception due to UL harmonic problem

Sensitivity degradation is allowed for a band if it is impacted by UL harmonic interference from another band part of the inter-band con-current V2X UE. Reference sensitivity exceptions (MSD) for the victim band (high) are specified in Table 7.3E.2.3.1-1 with uplink configuration of the aggressor band (low) specified in Table 7.3E.2.3.1-2.

V2X inter-band con-current band combinations	Operating Bands / Channel bandwidth of the affected DL band / MSD
	20	n38	10.7	7.7	5.8	4.7
NOTE 1: These requirements apply when there is at least one individual RE within the uplink transmission bandwidth of the aggressor (lower) for which the 3rd transmitter harmonic is within the sidelink transmission bandwidth of a victim (higher) band. NOTE 2: The requirements should be verified for UL EARFCN of the aggressor (lower) band (superscript LB such that in MHz and with the carrier frequency in the victim (higher) band in MHz and the channel bandwidth configured in the low band. NOTE 3: The MSD level applied to all supported SCSs in victim band.
