Dear all,
The [k,d] value-pair corresponds to slope (k) and intercept (d) of a linear approximation of the BICM curves around the SNR regime relevant for a given CQI.
I recommend reading the paper listed below that explain the details about this approximation :
– S. Schwarz, Ch. Mehlführer and M. Rupp “Low Complexity Approximate Maximum Throughput Scheduling for LTE”;
Best regards,
Fjolla
