Block Error Rate (BLER) is a ratio of the number of erroneous blocks to the total number of blocks transmitted on a digital circuit. It is used in measuring the error rate when extracting data frames from a Compact Disc (CD).

What is UL Bler in LTE?

BLER (in LTE) = Number of erroneous blocks / total number of received blocks. The calculation is based on CRC (Cyclic Redundancy Check) evaluation which is used for inspection the transport blocks at receiver side.

What is 5G Bler?

Within the physical and link layer field in 5G, block error rate (BLER) modelling is easily identified as a candidate for ML application [4]. A transport block in 5G [5] is a set of bits jointly coded by a low parity channel code (LDPC) after appending a cyclic redundancy check (CRC).
