Fig. 3-33: LTE Multi Evaluation: Power Dynamics, general time mask
The following statements apply also to power dynamics measurements with other time
masks.
The diagram shows the UE output power vs. time, sampled with 48 T
s
(1.5625 µs). The
measured trace covers the range from -1100 µs to +2098.4375 µs relative to the start
of the "Measure Subframe" (see
gram shows a subsection of the measured trace, depending on the configured time
mask.
The individual ON and OFF power areas are labeled in the diagram. ON power periods
are marked by a green horizontal bar. The measured subframe and an eventual SRS
period at the end of the "Measure Subframe" are indicated. Exclusion periods are
marked by gray vertical bars.
The table below the diagram shows a statistical evaluation of the ON power and OFF
power values. The table columns are not necessarily ordered in the same way as the
related diagram sections.
Depending on the selected time mask, the following results are available:
●
"ON Power, RMS/Peak":
Mean value and peak value of the UE output power over the "Measure Subframe"
(minus exclusion period and SRS period)
●
"OFF Power (after)", "ON Power (after)":
Mean power in one subframe after the "Measure Subframe" (minus exclusion
period)
●
"OFF Power (before)":
