How to read SINR measurements from all gNBs during a system level 5G simulation?

I am currently in the process of developing a 5G network simulation in MATLAB, which includes 3 gNBs and 15 UEs. I am interested in obtaining the SINR readings for all 15 UEs from each of the 3 gNBs during the simulation run. Ideally, I would like to have these readings in a 15x3 matrix format, where the first row represents the SINR readings from all 3 gNBs.
Since I am relatively new to MATLAB, I am basing my work on a specific example, so starting from there how can I achieve my needs stated above.
any guidance would be appreciated, thanks in advance.

Hi Zeyad,
As per my understanding, your goal is to obtain SINR (Signal-to-Interference-plus-Noise Ratio) reading for all 15 User Equipments from each of the 3 gNBs (next generation NodeBs) in a 5G network simulation, and organize these readings into a 15 x 3 matrix format.
The first step is to ensure you have defined the simulation parameters for your scenario, including the number of gNB's and UE's. I think in the example, gNB's and UE's are likely set up using configurations for their positions, transmission powers, antenna patterns, etc. You'll need to extend this setup to include 3 gNB's and 15 UE's. As the simulation runs, it will calculate various metrics, including SINR, for each UE based on the current network conditions, interference, and noise levels. To capture the SINR readings for all 15 UEs from each of the 3 gNBs, you'll need to modify the simulation loop or the part of the code responsible for calculating SINR.
The following code snippet provides a conceptual framework to adapt the MATLAB example for your specific simulation needs. The exact implementation details will depend on the structures and functions used in the example you're working from.
SINRMatrix = zeros(15, 3); % Initialize a 15x3 matrix to store SINR readings
for ueIdx = 1:15 % For each UE
for gnbIdx = 1:3 % For each gNB
% Calculate SINR for UE ueIdx from gNB gnbIdx
% This is a placeholder; you'll replace it with the actual SINR calculation
SINR = calculateSINR(ueIdx, gnbIdx);
% Store the SINR reading in the matrix
SINRMatrix(ueIdx, gnbIdx) = SINR;
end
end
heatmap(SINRMatrix);
xlabel('gNB Index');
ylabel('UE Index');
