Which of the following statistics are provided by the Probe's BLER statistics menu?

According to the Probe User Guide (V100R019C10_01) (PDF)-EN, the Probe’s BLER statistics menu provides the following statistics:

DIBLER: Downlink Initial Block Error Rate, which is the ratio of the number of erroneous downlink transport blocks to the total number of downlink transport blocks received by the UE in the first transmission.

DRBLER: Downlink Residual Block Error Rate, which is the ratio of the number of erroneous downlink transport blocks to the total number of downlink transport blocks received by the UE after all retransmissions.

Retransmission ratio: The ratio of the number of retransmitted downlink transport blocks to the total number of downlink transport blocks received by the UE.

The Probe’s BLER statistics menu does not provide the modulation scheme as a statistic. The modulation scheme is a parameter that determines the modulation and coding scheme (MCS) used for data transmission on the physical downlink shared channel (PDSCH). The modulation scheme can be QPSK, 16QAM, 64QAM, or 256QAM. The modulation scheme can be displayed on the Probe’s PDSCH configuration menu or PDSCH demodulation menu.

Therefore, the correct answer is A, B, and D.
