For 5G NR SA: I need to verify that my phy is supportive of 4 layers. It means that I need to maximize my ri as possible. I.e. ri (rank indicator) equal to 4.
Currently I can have maximum ri = 2 which I increased sinr as possible; so how do I arrive to ri=4?
Or in which way I can verify that my phy support 4 layers?
I want to validate that my phy support 4 layers; any clever checkpoint / suggestion that I execute which can proof that my phy support 4 layers?
Currently maximum value of ri is 2 with high possible sinr found.
