LTE: Periodic CSI Reporting Calculator

This Periodic CSI calculator can be used to calculate Periodic CQI/PMI/RI reporting instances in time domain (SFN and subframe) as well as the physical resource blocks used for transmitting PUCCH Format 2/2a/2b

In case where wideband CQI/PMI is configured, select K = 0. In case where Sub-band CQI/PMI reporting is configured, the value of K can be 1, 2, 3, or 4.

In order to find the time domain resources (SFN and subframe) for transmitting periodic CQI/PMI/RI, use button ‘Find CSI Occasions’. Similarly, for calculating frequency domain resources (physical resource blocks), one need to use ‘Find CSI Resources’ button.
