For inter-band NR CA between FR1 and FR2, output power dynamics as specified in TS 38.101-1 [2] and TS 38.101-2 [3] apply for FR1 and FR2 respectively.
6.3B Output power dynamics for DC
6.3B.0 General
The E-UTRA and NR switching time mask defines the observation period between E-UTRA subframe and NR slot/mini-slot boundary. Both E-UTRA subframe and NR slot/mini-slot have ON power transmissions. The ON power is defined as the mean power over the symbol duration excluding any transient period. For E-UTRA subframe or NR slot/mini-slot having OFF power transmission, the general time mask for E-UTRA or NR shall apply.
For inter-band EN-DC or NE-DC, output power dynamics requirement for E-UTRA single carrier and CA operation specified in clauses 6.3 and 6.3A of TS 36.101 [4] and for NR single carrier and CA operation specified in clause 6.3 and 6.3A of TS 38.101-1 [2] and for NR single carrier, CA operation and UL-MIMO specified in clause 6.3, 6.3A and 6.3D of TS 38.101-2 [3] apply.
6.3B.1 Output power dynamics for EN-DC with UL sharing from UE perspective
6.3B.1.1 E-UTRA and NR switching time mask for TDM based UL sharing from UE perspective
The E-UTRA and NR switching time mask is applicable for non-simultaneous transmissions between E-UTRA and NR in TDM based UL sharing from the UE perspective in the same channel, which is shared by E-UTRA and NR. The requirement applies on the condition that UE is capable of handling the uplink transmission timing difference between E-UTRA and NR which is less than or equal to [2.21]μs.
For UEs reporting E-UTRA and NR switching time capability of type 1 with switching time < 0.5 us for TDM based UL sharing from UE perspective within FR1 time masks in Figure 6.3B.1.1-1 and Figure 6.3B.1.1-2 shall apply. For UEs reporting E-UTRA and NR switching time capability of type 2 with switching time < 20 us for TDM based UL sharing from UE perspective within FR1, time masks in Figure 6.3B.1.1-3 and Figure 6.3B.1.1-4 shall apply. The additional time for the transient period on the succeeding E-UTRA subframe or NR slot is caused by the uplink transmission timing difference, for which the maximum value is [2.21]μs.

6.3B.1a Output power dynamics for NE-DC with UL sharing from UE perspective
The E-UTRA and NR switching time mask is applicable for non-simultaneous transmissions between E-UTRA and NR in TDM based UL sharing from the UE perspective in the same channel, which is shared by E-UTRA and NR. Unless otherwise specified, the 6.3B.1.1 clauses for NE-DC are applicable.
6.3B.2 Output power dynamics for intra-band EN-DC without dual PA capability
For intra-band contiguous EN-DC configurations DC_(n)41 and DC_(n)71, and all intra-band non-contiguous EN-DC configurations without dual PA capability, maximum UL switching time is defined as 120 us and DL reception interruption is allowed during UL switching. Time masks in Figure 6.3B.2-1 and Figure 6.3B.2-2 shall apply. Unless otherwise stated, for other intra-band contiguous EN-DC configurations, the switching time in 6.3B.1.1 applies.

6.3B.4 Output power dynamics for switching between two uplink carriers
6.3B.4.1 E-UTRA and NR switching time mask between two uplink carriers
In addition to the requirements in 6.3B.0 and the maximum output power requirement specified in Table 6.2B.1.3-1 with inter-band EN-DC (two bands), the switching time mask specified in this sub-clause is applicable for an uplink band pair of a inter-band EN-DC configuration without SUL band when the capability uplinkTxSwitchingPeriod is present, and is only applicable for uplink switching mechanisms specified in sub-clause 6.1.6 of TS 38.214 [14], where E-UTRA UL carrier 1 is capable of one transmit antenna connector and NR UL carrier 2 is capable of two transmit antenna connectors, and the two uplink carriers are in different bands with different carrier frequencies. The UE shall support the switch between single layer transmission with one antenna port and two-layer transmission with two antenna ports on the two uplink carriers following the scheduling commands and rank adaptation, i.e., both single layer and two-layer transmission with 2 antenna ports, and single layer transmission with 1 antenna port shall be supported on NR UL carrier 2.
The switching periods described in Figure 6.3B.4.1-1 are only located in NR carrier, and the length of uplink switching period X is less than the value indicated by UE capability uplinkTxSwitchingPeriod.
Figure 6.3B.4.1-1: Time mask for switching between E-UTRA UL carrier and NR UL carrier, where the switching period is located in NR carrier
The requirements apply for the case of co-located and synchronized network deployment with the max receiving timing difference of 3us between the two carriers.
6.3B.5 Output power dynamics for inter-band EN-DC
The switching time mask defined in this clause is applicable for a UE indicating support of IE singleUL-Transmission for the specific inter-band EN-DC combination for which only single switched UL is supported . The maximum UL switching time is defined as 120 us. Time masks in Figure 6.3B.5-1 and Figure 6.3B.5-2 shall apply.
