Minimum Test Time ← Confidence BLER
Specifies the minimum test time of a confidence BLER measurement as number of
processed subframes. During this time no pass/fail decision is allowed.
Minimum test times are for example specified in 3GPP TS 36.521 Annex G.4. They are
necessary if the test conditions introduce fluctuations disturbing the statistical inde-
pendence of the single bit error events (e.g. multipath fading). A minimum test time
ensures that the fluctuations are averaged out.
For FDD, all scheduled and unscheduled downlink subframes are considered. For
TDD, all downlink, uplink and special subframes are considered.
Option R&S CMW-KS510 is required.
Remote command:
Limit Error Rate ← Confidence BLER
Selects the limit error ratio for a confidence BLER measurement. The selection deter-
mines for example the used pass/fail decision rules.
The minimum test time and the error ratio calculation formula are independent of this
selection, so configure also these parameters as desired.
Option R&S CMW-KS510 is required.
"0.1%, 1%"
Pass/fail decision according to 3GPP TS 36.521 Annex G.4
"5%"
Pass/fail decision according to 3GPP TS 36.521 Annex G.2
Remote command:
2.4.19 RLC Throughput Measurement Configuration
The "Extended BLER" measurement is included in the "LTE signaling" application. To
access the measurement, press the softkey "LTE RX Meas" in the LTE signaling main
view. Then select the tab "RLC Throughput". The tab is described in this section.
2.4.19.1
Measurement Control
The measurement is turned on or off using the ON | OFF or RESTART | STOP keys.
