A.18 Monitor of BLER performance

The TB Error Rate in UL/DL can directly reflect the BLER, and has an influence on MCS selection and user throughput. It can be helpful to estimate the performance of radio resource management like radio resource schedulein transport layer and be helpful in trouble shooting. Furthermore, they should be taken into account to optimize the system performance. To obtain TB Error Rate by calculating, the number of total and error TBs transmitted in a cell should be monitored.
