Uplink RSSI Calculation in LTE

[rosan]

Hi Guys,

I want to understand how uplink RSSI is calculated in LTE. My main question is how MHA gain settings play a role in calculated RSSI values.

In 3G NodeB use the below formula to estimate the RTWP in antenna port based on the RSSI received in NodeB cabinet port. Please let me know if there is any equivalent formula in LTE;

3G Formula : ULRSSI (MHA installed) = RSSI NodeB Cabinet + FeederLoss − MHA Gain

Thanks
