WebAt the physical layer in 5G and LTE, typical BLER threshold defined is to be ≤10%. To maintain the BLER under this threshold, gNodeB’s use a link-adaptation algorithm based on the UE’s feedback to signal a lower MCS and coding scheme. Doing so increases the redundancy and reduces the spectral efficiency for reliable data transfer.
