Hi All,
Im just ramping on basic calculations for the RSSI in simulated env.
To simplify the things, initially i just configured , just one single cell, no neighbors (so there is no interference from neighbours), cell is not loaded.
i have configured 1.4MHz bandwidth (#6PRBs)
At some distance from the cell , i am measuring the RSRP which is -63.57dBm.
The RSSI, should ideally be around 12 times the RSRP (as there are mimimum 12 REs in 1.4Mz carrying the RS), and the noise.
So RSSI_in_mW > 12* RSRP_mW
RSRP-mW = 4.395 *10 pow(-7) mW
So RSSI_mW should be greater than > 12 *RSRP_mW
RSSI_dBm > (10 log 12 + 10 log RSRP_dBm)
1.7 - 6.3
RSSI_dBm > -4.6 dBm
Am i right ?
But the RSSI displayed is -52.778 dBm
Please kindly comment
thankyou
