Im bit new to phy concepts.
Actually googling gave me:
### RSSI = wideband power = noise + serving cell power + interference power
So, without noise and interference, we have that 100% DL PRB activity: RSSI=12 * N * RSRP
But my doubt is : Since RSRP is power of SINGLE RE. RSSI should correspond to power of single RE taking noise and interference into account. But then above formula should have been
RSSI = 12 * N * RSRP * 7
Because each RB in LTE is 7 symbols and 12 subcarriers ?
why is the 7 missing in the above equation
thanks a lot
