hi, lets consider S transmitted signal power, N noise power and I interference power:

SNR = S/N : SNR is signal to Noise ratio
SINR= S/(N+I) : SINR is signal to interference plus noise ratio
RS SNR: is reference signal signal to noise ratio,RS SNR should be higher than transmission power because RSs are important for :
1- making channel estimation and equalization and generating CQI (channel quality indicator) feedback
2- RS contains transmitted signals modulation and channel coding information so receiver can do demodulation and decoding operations.

Thank you, that you very much.

I want to calculate the Snr by myself and I can't do it. Could you please tell me how does the Nemo Analyzer calculate the Snr? Sinr = S/ (I+N) but I can't find the 13.1dB that the Nemo finds.
