PERFORMANCE INDICATORS
28
Table 5.1 shows the range of the modulation schemes and the CQI levels associated
with it. CQI values are reported from 0-15. The highest CQI 15 denotes the best channel
quality and thus is supported by highest modulation scheme available i.e. 64-QAM.
Apart from CQI, there are other channel estimation reports – Rank Indicator (RI) and
PMI that are associated with the MIMO. CQI measurements are reported at an interval
of one Transmission Time Interval TTI (1 ms). This causes measurement data to appear
redundant i.e. having multiple instances of link adaptations at the same time. [18]
