Help to remove Beamforming

[Angèle Hager Hafaiedh]

I work in an environment where i want 4 users to have identical SINR values:

-I set them very close together geographically

-I set an Isotropic antenna model for users and Gnb

I still couldn't find identical SINR values .

Did I miss something?

Thank you in advance

Yes, you did. Each tx-rx pair has its own channel realization, so even though they are close geographically, channel can be absolutely different.

That is a limitation on the 3GPP channel model. In the future you'll be able to use 5G-LENA with a ray-traced channel model, where that difference will go away.

Right now, what you could try is setting the same the exact same stream number to each individual UE.
