I’m trying to find what modulation and CQI use an specific UE.
The only way I figured out is the next one. Once you have the simulation statistics you can check
Average UE spectral eff.: 10.03 bit/cu (bit/symbol)
using configuration CLSM 2×2
I also found on the book The Vienna LTE-Advanced Simulators: Up and Downlink, Link and System Level page 34 table 2.2
a table comparing the bit/symbol values against the modulation and CQI but the values don’t match. There is no 10.03 so I assume I forgot something.
Does anyone know how to do it? What am I doing wrong?
On the book Vienna LTE-Advanced Simulators: Up and Downlink, Link and System Level page 34 table 2.2, it is given efficiency of each of the CQIs, while the parameter Average UE specral efficiency is measured in bit/channel use. The amount of channel uses (CUs) in a given transmission time interval (TTI) is calculated as 12 x 14 x (total number of assigned resource blocks (RBs) in this TTI). The numbers 12 and 14 refer to the number of subcarriers and OFDM symbols in one RB and TTI, respectively.
