6.2B.0 General
The requirements apply for inter-band NR-DC with one uplink serving cell configured per CG.
6.2B.1 UE maximum output power for NR-DC
For inter-band NR-DC with one uplink carrier assigned per NR band, the transmitter power requirements in clause 6.2 apply per band.
For inter-band NR-DC with one uplink assigned per band, the UE maximum output power shall be measured over all component carriers from different bands. If each band has separate antenna connectors, the maximum output power is defined as the sum of maximum output power from each UE antenna connector. The period of measurement shall be at least one sub frame (1 ms). The maximum output power is specified in Table 6.2B.1.3-1.

The UE is allowed to set its configured maximum output power PCMAX,f,c,MCG and PCMAX,f,c,SCG for the respective MCG and SCG and its total configured maximum output power for NR-DC operation with as specified in clause 7.6.2 of [8]. The UE is configured with an inter-CG power sharing mode by NR-DC-PC-mode.The requirements apply for one uplink serving cell configured per CG and for asynchronous and synchronous NR-DC if not otherwise stated.

PCMAX_H,f,c,MCG = MIN{PEMAX,c, PEMAX,NR-DC, PNR, PPowerClass – ΔPPowerClass}
for the MCG and
PCMAX_L,f,c,SCG = MIN{MIN(PEMAX,c , PEMAX,NR-DC, PNR) – ∆TC,c, (PPowerClass – ΔPPowerClass) – MAX(MAX(MPRc+∆MPRc, A-MPRc)+ ΔTIB,c + ∆TC,c + ∆TRxSRS, P-MPRc)}
PCMAX_H,f,c,SCG = MIN{PEMAX,c, PEMAX,NR-DC, PNR, PPowerClass – ΔPPowerClass}
for the SCG, where
– PEMAX,NR-DC is the value given by the field p-UE-FR1 of the PhysicalCellGroupConfig IE for the MCG as defined in [7];
– PNR is the value given by the field p-NR-FR1 of the PhysicalCellGroupConfig IE as defined in [7];
– PPowerClass is the maximum UE power specified in Table 6.2B.1.3-1 without taking into account the tolerance specified in the Table 6.2B.1.3-1;
– ∆TIB,c is the additional tolerance for serving cell c as specified in clause 6.2B.4.2 for NR-DC; ∆TIB,c = 0 dB otherwise;
– ∆TC,c = 1.5dB when NOTE 2 in Table 6.2B.1.3-1 applies for a serving cell c, otherwise ∆TC,c = 0 dB ;
– ∆MPRc for serving cell c is specified in clause 6.2.2.
– ΔPPowerClass = 0 dB for a power class 3 capable UE.
When MSG or SCG are configured with intra-band contiguous carrier aggregation, then intra-band carrier aggregation PCMAX,CA,MCG (q) and/or PCMAX,CA,SCG (q) in physical-channel q shall be set within the bounds:
PCMAX_L,CA, MCG (q) ≤ PCMAX,CA,MCG (q) ≤ PCMAX_H,CA,MCG (q)
for MSG, and/or
PCMAX_L,CA,SCG (q) ≤ PCMAX,CA,SCG (q) ≤ PCMAX_H,CA,SCG (q)
for SCG, where PCMAX_L,CA,MCG, PCMAX_H,CA,MCG, PCMAX,CA,SCG and PCMAX_H,CA,SCG are the limits for a carrier aggregation uplink as specified in clause 6.2A.4.1.1 modified as follows:
PCMAX_L,CA,MCG = MIN{10 log10 ∑ pEMAX,c – TC , PEMAX,CA, PEMAX,NR-DC, PNR,MCG, (PPowerClass – ΔPPowerClass) – MAX(MAX(MPR, A-MPR) + ΔTIB,c + TC + TRxSRS, P-MPRc ) }
PCMAX_H,CA,MCG = MIN{10 log10 ∑ pEMAX,c , PEMAX,CA , PEMAX,NR-DC, PNR,MCG, PPowerClass – ΔPPowerClass }

PCMAX_L,CA,SCG = MIN{10 log10 ∑ pEMAX,c – TC , PEMAX,CA, PEMAX,NR-DC, PNR,SCG, (PPowerClass – ΔPPowerClass) – MAX(MAX(MPR, A-MPR) + ΔTIB,c + TC + TRxSRS, P-MPRc ) }
PCMAX_H,CA,SCG = MIN{10 log10 ∑ pEMAX,c , PEMAX,CA , PEMAX,NR-DC, PNR,SCG, PPowerClass – ΔPPowerClass }
for SCG.
For a UE provided with NR-DC-PC-mode = Semi-static-mode1,
= MIN{PEMAX, NR-DC, PPowerClass} + 0.3 dB
with PPowerClass set to power class 3 in case the UE indicates a higher power class in any CG. The UE determines the maximum transmission power for the MCG and the SCG using the respective configured maximum power PCMAX,f,c,MCG and PCMAX,f,c,SCG for a single serving cell per band or PCMAX,CA,MCG and/or PCMAX,CA,SCG when it is configured with contiguous intra-band carrier aggregation in one or both cell groups.
If for synchronous NR-DC operation a UE is provided NR-DC-PC-mode = Semi-static-mode2, the is determined as above and
– if at least one symbol of slot of the MCG/SCG is indicated as uplink or flexible to a UE by tdd-UL-DL-ConfigurationCommon and tdd–UL-DL-ConfigurationDedicated, if provided, overlaps with a symbol for any ongoing transmission overlapping with slot of the SCG/MCG, the UE determines a maximum power for the transmission on the SCG/MCG overlapping with slot using the configured maximum power PCMAX,f,c,SCG or PCMAX,f,c,MCG or PCMAX,CA,MCG and/or PCMAX,CA,SCG when it is configured with intra-band contiguous carrier aggregation in one or both cell gropups for the SCG or MSG, respectively,
– otherwise (i.e. an ongoing transmission overlapping with slot of the SCG/MCG overlaps with only semi-static downlink symbols within slot of the MCG/SCG), the UE determines a maximum power for the transmission on MCG or the SCG overlapping with slot using the configured maximum power as specified in clause 6.2.4 or the modified 6.2A.4.1.1 as described in this clause.
If a UE indicates a capability for dynamic power sharing between the MCG and the SCG and is provided with NR-DC-PC-mode = Dynamic,
= MIN{PEMAX, NR-DC, PPowerClass}
with PPowerClass set to power class 3 in case the UE indicates a higher power class in any CG. The UE determines the maximum transmission power for the MCG and the SCG using the respective configured maximum power PCMAX,f,c,MCG and PCMAX,f,c,SCG or PCMAX,CA,MCG and/or PCMAX,CA,SCG or a combination of PCMAX,f,c,MCG or PCMAX,f,c,SCG and PCMAX,CA,MCG or PCMAX,CA,SCG when it is configured with intra-band contiguous carrier aggregation in one or both cell groups except
– if UE transmission(s) in slot of the MCG or in slot of the SCG do not overlap in time with any UE transmission(s) on the SCG or the MCG, respectively, the UE determines a maximum transmission power in slot of the MCG or in slot of the SCG using the configured maximum power as specified in clause 6.2.4 or the modified 6.2A.4.1.1 as described in this clause for the uplink contiguous carrier aggregation configured cell group.
If a UE indicates a capability to determine a total transmission power on the SCG at a first symbol of a transmission occasion on the SCG by determining transmissions on the MCG as specified in clause 7.6.2 of [8], and is provided with NR-DC-PC-mode = Dynamic,
= MIN{PEMAX, NR-DC, PPowerClass}
with PPowerClass set to power class 3 in case the UE indicates a higher power class in any CG. The UE determines the maximum transmission power for the MCG and the SCG using the respective configured maximum power PCMAX,f,c,MCG and PCMAX,f,c,SCG or PCMAX,CA,MCG and/or PCMAX,CA,SCG or a combination of PCMAX,f,c,MCG or PCMAX,f,c,SCG and PCMAX,CA,MCG or PCMAX,CA,SCG when it is configured with intra-band contiguous carrier aggregation in one or both cell groups.
The measured total maximum output power PUMAX over both CGs measured over the transmission reference time duration is
PUMAX = 10 log10 (pUMAX, MCG + pUMAX, SCG),
where pUMAX, MSG and pUMAX, SCG denote the measured output power of serving cells contained in the respective MSG and SCG expressed in linear scale.
The measured total configured maximum output power PUMAX shall be within the following bounds:
PCMAX_L -TLOW (PCMAX_L) ≤ PUMAX ≤ PCMAX_H + THIGH (PCMAX_H)
with the tolerances TLOW(PCMAX_H) and THIGH(PCMAX_H) for applicable values of PCMAX specified in Table 6.2B.4.1.3-2.
When a subframe p on the MSG overlap with a physical-channel q on the SCG, then for PUMAX evaluation, the subframe p on the MCG is taken as reference period TREF and always considered as the reference measurement duration and the following rules are applicable.
TREF and Teval are specified in Table 6.2B.4.1.3-1 when same or different subframe and physical-channel durations are used on the carriers. The PPowerClass shall not be exceeded by the UE during any evaluation period of time.

For each TREF, the PCMAX_H is evaluated per Teval and given by the maximum value over the transmission(s) within the Teval as follows:
PCMAX_H = MAX{PCMAX_NR-DC_H(p,q), PCMAX_NR-DC_H(p,q+1), … , PCMAX_NR-DC_H(p,q+n)}
where PCMAX_NR-DC_H entries are the applicable upper limits for each overlapping scheduling unit pairs (p,q), (p, q+1), up to (p, q+n) for each applicable Teval duration, where q+n is the last physical-channel on the SCG overlapping with subframe p on the MCG, while PCMAX_L is computed as follows:
PCMAX_L = MIN{PCMAX_NR-DC_L(p,q), PCMAX_NR-DC_L(p,q+1), … , PCMAX_NR-DC_L(p,q+n)}
where PCMAX_NR-DC_L entries are the applicable lower limits for each overlapping scheduling unit pairs (p,q), (p, q+1) up to (p, q+n) for each applicable Teval duration, where q+n is the last physical-channel on the SCG overlapping with subframe p on the MCG.
For a UE provided with NR-DC-PC-mode = Semi-static-mode1 and configured with pNR,MCG + pNR,SCG ≤ with pNR,MCG and pNR,SCG the values of the PNR for the respective MCG and SCG expressed in linear scale

where
