This requirement does not apply to E-UTRA operation.
6.3.3 Power control dynamic range
6.3.3.1 General
The power control dynamic range is the difference between the maximum and the minimum code domain power of a code channel for a specified reference condition.
This requirement applies at each TAB connector supporting transmission in the operating band.
6.3.3.2 Minimum requirement for MSR operation
For UTRA FDD operation the minimum requirements for MSR AAS BS power control dynamic range are the same as in 3GPP TS 25.104 [6], subclause 6.4.2.1.

6.3.4 Total power dynamic range
6.3.4.1 General
The total power dynamic range is the difference between the maximum and the minimum output power for a specified reference condition.
This requirement applies at each TAB connector supporting transmission in the operating band.
NOTE 1: The upper limit of the dynamic range is the BS maximum output power (PRated,c,TABC). The lower limit of the dynamic range is the lowest minimum power from the BS when no traffic channels are activated.
Particularly for E-UTRA and NR, the total power dynamic range is the difference between the maximum and the minimum transmit power of an OFDM symbol for a specified reference condition.
NOTE 2: The upper limit of the dynamic range at a TAB connector is the OFDM symbol power when transmitting on all RBs at maximum output power (PRated,c,TABC). The lower limit of the dynamic range at a TAB connector is the OFDM symbol power when one resource block is transmitted. The OFDM symbol carries PDSCH or sPDSCH and not contain RS, PBCH or synchronization signals.
