For a given serving cell, if the UE is configured with higher layer parameter shortProcessingTime , the UE shall use the TPC command received with DCI format 0/4 mapped onto the UE-specific search space for subframe i.
For a UE capable of simultaneous transmission of different uplink signal durations to different serving cells as indicated by UE capability simultaneousTx-differentTx-duration, if PUSCH/PUCCH transmissions of different duration occur in different serving cells and in the same subframe and if the total transmit power of the UE would exceed 
, the UE shall follow the dropping rules described in Clause 5.1.5 until the total transmit power of the UE would not exceed 
or until there are only PUSCH/PUCCH transmissions of the same duration remaining in which case the following rules apply.
If the UE is not configured with an SCG or a PUCCH-SCell, and if the total transmit power of the UE would exceed

If the UE is not configured with an SCG or a PUCCH-SCell, and if the UE has PUSCH transmission with UCI on serving cell j and PUSCH without UCI in any of the remaining serving cells, and the total transmit power of the UE would exceed

For a UE not configured with a SCG or a PUCCH-SCell, note that
values are the same across serving cells when
but for certain serving cells 
may be zero.
If the UE is not configured with an SCG or a PUCCH-SCell, and if the UE has simultaneous PUCCH and PUSCH transmission with UCI on serving cell j and PUSCH transmission without UCI in any of the remaining serving cells, and the total transmit power of the UE would exceed

for a given serving cell in a TAG overlaps some portion of the first symbol of the PUSCH transmission on subframe/slot/subslot 
for a different serving cell in another TAG the UE shall adjust its total transmission power to not exceed 
on any overlapped portion.
– If the UE is configured with multiple TAGs, and if the PUSCH transmission of the UE on subframe/slot/subslot 
for a given serving cell in a TAG overlaps some portion of the first symbol of the PUCCH transmission on subframe/slot/subslot 
for a different serving cell in another TAG the UE shall adjust its total transmission power to not exceed 
on any overlapped portion.
– If the UE is configured with multiple TAGs, and if the trigger type 0/1 SRS transmission of the UE in a symbol on subframe/slot/subslot 
for a given serving cell in a TAG overlaps with the PUCCH/PUSCH transmission on subframe/slot/subslot or subframe/slot/subslot 
for a different serving cell in the same or another TAG the UE shall drop trigger type 0/1 SRS if its total transmission power exceeds

– If the UE is configured with multiple TAGs and more than 2 serving cells, and if the trigger type 0/1 SRS transmission of the UE in a symbol on subframe/slot/subslot 
for a given serving cell overlaps with the SRS transmission on subframe/slot/subslot 
for a different serving cell(s) and with PUSCH/PUCCH transmission on subframe/slot/subslot

– If the UE is configured with multiple TAGs, the UE shall, when requested by higher layers, to transmit PRACH in a secondary serving cell in parallel with SRS transmission in a symbol on a subframe of a different serving cell belonging to a different TAG, drop SRS if the total transmission power exceeds 
on any overlapped portion in the symbol.
– If the UE is configured with multiple TAGs, the UE shall, when requested by higher layers, to transmit PRACH in a secondary serving cell in parallel with PUSCH/PUCCH in a different serving cell belonging to a different TAG, adjust the transmission power of PUSCH/PUCCH so that its total transmission power does not exceed 
on the overlapped portion.
If the UE is configured with a LAA SCell for uplink transmissions, the UE may compute the scaling factor 
assuming that the UE performs a PUSCH transmission on the LAA SCell in subframe i irrespective of whether the UE can access the LAA SCell for the PUSCH transmission in subframe i according to the channel access procedures described in Clause 4.2.1 of [13].
For a BL/CE UE configured with CEModeA, if the PUSCH transmission, scheduled by one DCI, is transmitted in more than one subframe i0, i1, …, iN-1 where i0< i1< …< iN-1, the PUSCH transmit power in subframe ik , k=0, 1, …, N-1, is determined by
except in case the DCI contains an UL index set to ‘11’.
For a BL/CE UE configured with CEModeB, the PUSCH transmit power in subframe ik is determined by
5.1.1.2 Power headroom
There are three types of UE power headroom reports defined. A UE power headroom
is valid for subframe/slot/subslot i for serving cell 
.
If the UE is configured with a SCG, and if the higher layer parameter phr-ModeOtherCG-r12 for a CG indicates ‘virtual’, for power headroom reports transmitted on that CG, the UE shall compute PH assuming that it does not transmit PUSCH/PUCCH on any serving cell of the other CG.
For a UE configured with EN-DC/NE-DC and capable of dynamic power sharing, if a NR Multiple Entry PHR [15, TS 38.321] is triggered and if the NR slot on active UL BWP that carries the Multiple Entry PHR is not aligned with E-UTRA subframe due to asynchronous EN-DC/NE-DC [16, TS 38.133] or different duration between the NR slot and E-UTRA subframe, UE provides PH of the first E-UTRA subframe that overlaps with the NR slot.
If the UE is configured with a SCG,
– For computing power headroom for cells belonging to MCG, the term ‘serving cell’ in this clause refers to serving cell belonging to the MCG.
– For computing power headroom for cells belonging to SCG, the term ‘serving cell’ in this clause refers to serving cell belonging to the SCG. The term ‘primary cell’ in this clause refers to the PSCell of the SCG.
If the UE is configured with a PUCCH-SCell,
– For computing power headroom for cells belonging to primary PUCCH group, the term ‘serving cell’ in this clause refers to serving cell belonging to the primary PUCCH group.
– For computing power headroom for cells belonging to secondary PUCCH group, the term ‘serving cell’ in this clause refers to serving cell belonging to the secondary PUCCH group. The term ‘primary cell’ in this clause refers to the PUCCH-SCell of the secondary PUCCH group.
In this clause,
– the term ‘scheduled to transmit PUSCH’ refers to PUSCH scheduled via an uplink scheduling grant or semi-persistent scheduling assignment.
– the terms ‘PUCCH is prepared to be transmitted’ or ‘prepared to transmit PUCCH’ refer to PUCCH for which the UE has started generating the UCI.
If the UE is configured with a LAA SCell for uplink transmissions, and the UE receives PDCCH/EPDCCH with DCI format 0A/0B/4A/4B with PUSCH trigger A set to 0 corresponding to a PUSCH transmission on the LAA SCell in subframe i, power headroom for subframe i is computed assuming that the UE performs a PUSCH transmission on the LAA SCell in subframe i irrespective of whether the UE can access the LAA SCell for the PUSCH transmission in subframe i according to the channel access procedures described in Clause 4.2.1 of [13].
If the UE is configured with an LAA SCell for uplink transmissions, and if the UE reports power headroom in subframe i in serving cell c in a PUSCH transmission scheduled using DCI format 0A/0B/4A/4B with ‘PUSCH trigger A’ set to 0 or in a PUSCH transmission scheduled using DCI format 0/4,
