In HSPA evolution different scheduling mechanism are defined. For Network Operators to use the related licenses more efficient it is important to know the utilization of the different scheduling mechanism. Based on the utilization information operator can optimize their license usage by moving licenses to the areas where the utilization is higher.

The utilization of 64QAM and MIMO scheduling mechanism is calculated based in the scheduled TTIs. The measurements required are: how many TTIs using 64QAM technology in UTRAN cell are actually scheduled by NodeB, how many TTIs in UTRAN cell are actually scheduled by NodeB of using MIMO technology and how many TTIs are actually scheduled in total. The first counter can be used to calculate the usage of 64QAM technology in the networks, by comparing this measurement to the total number of scheduled TTIs. The second counter reflects the utilization of MIMO technology in the networks by comparing this measurement to the total number of scheduled TTIs. The last counter reflects the total number of scheduled TTIs where the empty TTIs are excluded.
