Hi,

Frequency selective scheduling (FSS) :
This is one type of scheduling algorithm which improves data rates be scheduling UE in particular RBG(RB group). UE will send sub band CQI based on these ENB will take a decision which sub band is good for UE then it will schedule data in those RBG.

LTE : What information is sent in buffer status report from UE to eNodeB ?

I know buffer status report is sent from UE to eNodeB to request for UL resources. Can someone please explain how many types of buffer status reports have been defined till now and in what scenarios each one is used ?

How the Symbols sent in a slot with perfect timing in LTE ???

Each carrier in LTE is 15khz so in a calculation i found that useful symbol time = 1/15khz = 66.6 mircosec

wrt to this
Each symbol duration is calculated like this
Normal Cyclic Prefix length = 4.69 microsec --- so each symbol in this = 66.6 + 4.69 = 71.29 microsec
Extended Cyclic Prefix length = 16.67 microsec ----so each symbol in this = 66.6 + 16.67 = 83.27 microsec

So Normal cyclic prefix Slot (7 symbols) duration = 71.29 * 7 = 499.03 microsec(0.49903 millis)
and Extended cyclic prefix Slot (6 symbols) duration = 83.27 * 6 = 499.63 microsec (0.49963 millis)

But slot duration is fixed as 0.5 ms ...

So does this slight difference creates any problem ???
How real time it works ???
