6.2B.2.0 General

The UE maximum output power reduction (MPR) specified in this clause is applicable for UEs configured with EN-DC when NS_01 is indicated in the MCG and the SCG. The MPR applies subject to indication in the field modifiedMPRbehavior for the SCG [2].

6.2B.2.1 Intra-band contiguous EN-DC

6.2B.2.1.1 General

When the UE is configured for intra-band contiguous EN-DC, the UE determines the total allowed maximum output power reduction as specified in this clause.

For UE supporting dynamic power sharing the following:

– for the MCG, MPRc in accordance with TS 36.101 [4]

– for the SCG,

MPR’c = MPRNR = MAX( MPRsingle,NR, MPRENDC)

– for the total configured transmission power,

MPRtot = PPowerClass,EN-DC – min(PPowerClass,EN-DC ,10*log10(10^((PPowerClass,E-UTRA – MPRE-UTRA)/10) + 10^((PPowerClass,NR – MPRNR)/10))

where

MPRE-UTRA = MAX(MPRsingle,E-UTRA, MPRENDC )

with

– MPRsingle, E-UTRAis the MPR defined for the E-UTRA transmission in TS 36.101 [4]

– MPRsingle,NR is the MPR defined for the NR transmission in TS 38.101-1 [2]

For UEs not supporting dynamic power sharing the following

– for the MCG,

MPRc = MAX(MPRsingle,E-UTRA, MPRENDC )

– for the SCG,

MPR’c = MAX( MPRsingle,NR, MPRENDC )

where

– MPRsingle,NR is the MPR defined for the NR transmission in TS 38.101-1 [2]

MPRENDC is defined in Clause 6.2B.2.1.2

6.2B.2.1.2 MPR for power class 3 and power class 2

MPR in this clause is applicable for power class 3 and power class 2 UEs indicating IE dualPA-Architecture supported with EN-DC power class being the same as the E-UTRA and NR power class, otherwise the UE can use as much MPR as needed to fulfil emissions requirements when scheduled with dual uplink transmission. For UEs scheduled with single uplink transmission, MPR in clause 6.2.4 of TS 36.101 [4] and 6.2.2 of TS 38.101-1 [2] apply. For a UE supporting dynamic power sharing for DC_(n)71AA for which dual simultaneous uplink transmissions are mandatory and A-MPR defined in clause 6.2B.3.1.1 is applied as MPR. The allowed maximum output power reduction applied to transmission on the MCG and the SCG is defined as follows:

MPRENDC = MA

Where MA is defined as follows

MA = 15 ; 0 ≤ B < 0.5

10 ; 0.5 ≤ B < 1.0

8 ; 1.0 ≤ B < 2.0

6 ; 2.0 ≤ B

Where:

For UEs supporting dynamic power sharing,

B = (LCRB_alloc, E-UTRA * 12* SCSE-UTRA + LCRB_alloc,NR * 12 * SCSNR)/1,000,000

For UEs not supporting dynamic power sharing,

For E-UTRA

B = (LCRB_alloc, E-UTRA * 12* SCSE-UTRA + 12 * SCSNR)/1,000,000

Where SCSNR = 15,000 Hz is assumed in calculation of B.

For NR

B = (12* SCSE-UTRA + LCRB_alloc,NR * 12 * SCSNR)/1,000,000

Where SCSE-UTRA = 15,000 Hz is assumed in calculation of B.

and MA is reduced by 1 dB for B < 2.

6.2B.2.2 Intra-band non-contiguous EN-DC

6.2B.2.2.1 General

When the UE is configured for intra-band non-contiguous EN-DC, the UE determines the total allowed maximum output power reduction as specified in this clause.

– for the SCG,

MPR’c = MPRNR = MAX( MPRsingle,NR, MPRENDC)

– for the total configured transmission power,

MPRtot = PPowerClass,EN-DC – min(PPowerClass,EN-DC ,10*log10(10^((PPowerClass,E-UTRA – MPRE-UTRA)/10) + 10^((PPowerClass,NR – MPRNR)/10))
