I want to change FB_period for feedback.
I read a paper “Resource Allocation and Link Adaptation in LTE and LTE Adavanced: A Tutorial”.
In here, they said there are two CQI reporting method: Aperiodic CQI reporting & Periodic CQI reporting.
In this simulator,
– Can I feedback only periodically, or I can feedback Aperiodically?
– Can I set FB_periode any number?
(In Periodic CQI reporting via PUCCH case,
In TDD mode, the possible reporting periods are 1,5,10,20,40,80 and 160 sub-frames
In FDD mode, the possible reporting periods are 2,5,10,20,32,40,64,80,128, and 160 sub-frames ; these values go)
Furthermore, this simulation is based on TDD mode? Or FDD mode?
Basically, the CQI feedback is calculated in every subframe and reported back, with a certain adjustable delay. Meaning that the reported CQI values are stored in a FIFO buffer and exploited at a later TTI.
Our simulator currently supports only FDD mode with CQI reporting every TTI. If you want to enable periodic CQI reporting with a periodicity larger than one TTI, or even a-periodic reporting, you would have to modify this buffering structure to fit your requirements.
