How to simulate 5G network projects using simulators?

The simulation of 5G network projects with the support of simulators is examined as an interesting and important process. To simulate 5G network projects through the use of prominent simulators such as NS-3, OMNeT++ along with Simu5G, and MATLAB including 5G Toolbox, we suggest step-by-step instructions in an explicit manner: 

1. Simulating 5G Networks with MATLAB 5G Toolbox

Procedural Instruction:

1. Arrange MATLAB Platform: Initially, you should make sure that you have MATLAB installed on your system, along with a significant 5G Toolbox.
2. Determine System Parameters: For the 5G network, configure the fundamental parameters.

% System parameters

carrierFrequency = 28e9; % 28 GHz

bandwidth = 100e6; % 100 MHz

numAntennas = 64; % Number of antennas in the array

numUsers = 10; % Number of users

3. Develop Channel Model: Specifically for the simulation, outline the channel model.

% Create a 5G TDL-C channel model

channel = nrTDLChannel;

channel.NumTransmitAntennas = numAntennas;

channel.NumReceiveAntennas = 1;

channel.DelayProfile = ‘TDL-C’;

channel.DelaySpread = 100e-9; % 100 ns

channel.MaximumDopplerShift = 300; % 300 Hz

disp(channel);

4. Resource Allocation: Then, plan to allot resources to the appropriate users.

% Resource allocation (simple Round Robin)

numRBs = 100; % Number of resource blocks

allocation = zeros(numUsers, numRBs);

for rb = 1:numRBs

    userIdx = mod(rb, numUsers) + 1;

    allocation(userIdx, rb) = 1;

end

5. Beamforming: In the direction of the users, navigate the antenna array by applying beamforming techniques.

% Beamforming using simple steering vector

angles = linspace(-60, 60, numUsers); % User angles in degrees

steeringVector = phased.SteeringVector(‘SensorArray’, phased.ULA(‘NumElements’, numAntennas));

weights = zeros(numAntennas, numUsers);

for k = 1:numUsers

    weights(:, k) = steeringVector(carrierFrequency, angles(k));

end

6. Execute Simulation and Examine Performance: The performance metrics such as SINR has to be examined after the simulation execution.

% Example SINR calculation

rxSignal = complex(randn(1000, numUsers), randn(1000, numUsers)); % Dummy received signal

noisePower = 1e-3; % Noise power

sinr = zeros(1, numUsers);

for k = 1:numUsers

    signalPower = norm(rxSignal(:, k))^2;

    interferencePower = sum(norm(rxSignal(:, [1:k-1, k+1:end])).^2);

    sinr(k) = signalPower / (interferencePower + noisePower);

end

% Display SINR for each user

disp(sinr);

2. Simulating 5G Networks with ns-3

Procedural Instruction:

1. Configure ns-3 Platform: In the beginning, NS-3 and the relevant 5G modules (such as mmWave, LENA) have to be installed.
2. Create Simulation Script: To specify the simulation platform and network parameters, a simulation script must be developed in Python or C++.

// Example C++ script for ns-3

#include “ns3/core-module.h”

#include “ns3/network-module.h”

#include “ns3/internet-module.h”

#include “ns3/point-to-point-module.h”

#include “ns3/applications-module.h”

#include “ns3/lte-module.h”

#include “ns3/mobility-module.h”

using namespace ns3;

int main(int argc, char *argv[])

{

    // Set up simulation parameters

    uint16_t numberOfNodes = 10;

    double simTime = 1.0; // seconds

    // Create nodes

    NodeContainer ueNodes;    ueNodes.Create(numberOfNodes);

    NodeContainer enbNodes;

    enbNodes.Create(1);

    // Set up mobility model

    MobilityHelper mobility;    mobility.SetMobilityModel(“ns3::ConstantPositionMobilityModel”);    mobility.Install(enbNodes);    mobility.SetMobilityModel(“ns3::RandomWalk2dMobilityModel”, “Bounds”, RectangleValue(Rectangle(-500, 500, -500, 500)));

    mobility.Install(ueNodes);

    // Install LTE Devices to the nodes

    NetDeviceContainer enbLteDevs;

    NetDeviceContainer ueLteDevs;

    LteHelper lteHelper;

    enbLteDevs = lteHelper.InstallEnbDevice(enbNodes);

    ueLteDevs = lteHelper.InstallUeDevice(ueNodes);

    // Attach UEs to the eNodeB

    lteHelper.Attach(ueLteDevs, enbLteDevs.Get(0));

    // Install the IP stack on the UEs

    InternetStackHelper internet;

    internet.Install(ueNodes);

    // Assign IP addresses to the UEs

    Ipv4InterfaceContainer ueIpIface;

    ueIpIface = epcHelper->AssignUeIpv4Address(NetDeviceContainer(ueLteDevs));

    // Attach the applications to the UEs

    uint16_t dlPort = 1234;

    ApplicationContainer clientApps;

    ApplicationContainer serverApps;

    UdpClientHelper dlClient(ueIpIface.GetAddress(0), dlPort);    dlClient.SetAttribute(“MaxPackets”, UintegerValue(1000000));    dlClient.SetAttribute(“Interval”, TimeValue(Seconds(0.01)));    dlClient.SetAttribute(“PacketSize”, UintegerValue(1024));    serverApps.Add(dlClient.Install(ueNodes.Get(0)));

    // Run the simulation    Simulator::Stop(Seconds(simTime));

    Simulator::Run();

    // Clean up

    Simulator::Destroy();

    return 0;

}

        int numUEs = default(10);

    submodules:

        enb: Simu5GEnb {

            parameters:
