LTE Made Easy



LTE Fundamentals:

1. What is Physical resource block?




2. LTE BW vs Resource Blocks:







BW of a PRB is 180 khz
so, 20mz contains 100PRB==>100*180K==>18Mhz+2(Gaurd Band)
                               50PRB==>50*180K==>9Mhz+1(Gaurd Band)

3. What is RSRQ:

RSRQ=N*((RSRP)/(RSSI))
