6.3.5FA.1.3 Minimum conformance requirements
The minimum requirement for absolute power tolerance is given in Table 6.3.5FA.1.3-1 over the power range bounded by the Maximum output power as defined in subclause 6.2.2FA and the Minimum output power as defined in subclause 6.3.2F.

In case of -15 dB ≤ Ês/Iot < -6 dB, the absolute power tolerance given in Table 6.3.5FA.1.3-2 applies if the UE transmit power is not mandated to be PCMAX,c according to the UE uplink power control procedure or random access procedure in Section 16 of [6] (e.g. the lowest configured repetition level is used for NPRACH transmission or the number of repetitions of the allocated NPUSCH RUs is no more than 2).

6.3.5FA.2.3 Minimum conformance requirements
Category NB1 and NB2 UE relative power control requirement is defined for NPRACH power step values of 0, 2, 4 and 6 dB. For NPRACH transmission, the relative tolerance is the ability of the UE transmitter to set its output power relatively to the power of the most recently transmitted preamble. The measurement period for the NPRACH preamble is specified in Table 6.3.4F.2-1.
The requirements specified in Table 6.3.5F.2-1 apply when the power of the target and reference sub-frames are within the power range bounded by the Minimum output power as defined in subclause 6.3.2F and the maximum output power as defined in subclause 6.2.2FA.

The power step (ΔP) is defined as the difference in the calculated setting of the UE transmit power between the target and reference sub-frames. The error is the difference between ΔP and the power change measured at the UE antenna port with the power of the cell-specific reference signals kept constant. The error shall be less than the relative power tolerance specified in Table 6.3.5FA.2.3-1.

6.3.5FA.3 Aggregate power control tolerance for category NB1 and NB2/Power Class 6
6.3.5FA.3.1 Test purpose
To verify the ability of a category NB1 and NB2 UE to maintain its output power in non-contiguous transmission with respect to the first UE transmission, when the uplink power control parameters as defined in TS 36.213 are constant and α is set to 0.
6.3.5FA.3.2 Test applicability
This test case applies to all types of E-UTRA FDD Power Class 6 UE release 14 and forward of category NB1 and NB2.
6.3.5FA.3.3 Minimum conformance requirements
Category NB1 and NB2 aggregate power control tolerance is the ability of a UE to maintain its output power in non-contiguous transmission with respect to the first UE transmission, when the uplink power control parameters as defined in TS 36.213 are constant and α is set to 0.
The UE shall meet the requirements specified in Table 6.3.5F.3.1-1 for aggregate power control over the power range bounded by the minimum output power as defined in subclause 6.3.2F and the maximum output power as defined in subclause 6.2.2FA.
