SINR Calculation: Hand calculated vs found in DlDataSINR

[Angèle Hager Hafaiedh]

I wanted to handwrite the calculation of the final SINR values that are found in SlDataSINR.

1-Compute per-RB raw SINR:
SINRlinear=𝑆/(𝐼+𝑁)

2Compute link-budget signal power S:
𝑆=Ptx,RB*Gue/𝐿pathloss
Gue:user gain
Ptx,RB: Tx Power per RB

3-Compute noise power 𝑁
𝑁=𝑘*𝑇*𝐵rb*𝐹
𝐵rb: bandwidth of a RB

4-Compute raw SINR in dB:
SINRraw(dB)=10log10(𝑆/N)

5-Add beamforming gain:
SINRBF(dB)=SINRraw(dB)+GBF, TX+GBF, RX
GBF, TX: Tx Beamforming gain
GBF, RX: Rx Beamforming gain

6-I didn't use EESM since i am dealing with one channel

However The values I found are different than what I found in my code. I don't think interference is explicitly mentionned in my code.

So why can't I find the exact values?

Thank you in advance
