Information from the core requirements in TS 38.101-2 [3], TS 38.213 [19] and the uncertainties in Annex F applicable to the Test case are used to derive the uplink power window. There are 4 stages:

– Find the uplink power target value.

– Determine how closely the uplink power can be set to the target value.

– Include the effect of test system uncertainty.

– Position the Uplink power window centred on the target value.

This process is shown in the diagram below, using values for FR2a and P_UMAX ≥ P > P_int and taking an example where the target value is +15dBm:

The smallest UE Power step size is defined in TS 38.213 [9] Table 7.1.1-1, for absolute .

The UE Power step size tolerance is defined in TS 38.101-2 [3] Table 6.3.4.3-1 and Table 6.3.4.3-2, for PUSCH to PUSCH transitions with the allocated resource blocks fixed in frequency and no transmission gaps other than those generated by downlink subframes, Guard Periods, and for a power step ΔP = 1 dB.

The Test system uncertainties are defined in Annex F of the present document.

To ensure that the actual UE uplink power is centred on the target value, UE uplink power measured by the test system should remain within the smaller Uplink power control window shown in Figure F.4.4.2-1.
