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');
