Hello Shan,
As per my understanding, you want to add multiple bearers per UE in 5G NR(New Radio) Toolbox system level simulation.
Please note that to create a scenario with multiple data bearers for a single UE in a 5G simulation, you can set up the simulation environment and then retrieve data for each bearer in the `nrScheduler.m` file. Here's a general approach to achieve this:
- Setting up the Simulation Environment
1. Network Configuration: Define the network configuration parameters including the number of UEs, and the characteristics of the bearers (e.g., priority, bandwidth allocation, etc.).
2. UE Configuration: Configure the UE parameters including the number of bearers, QoS requirements, and other relevant settings.
3. Scheduler Configuration: Set up the scheduler parameters including the scheduling algorithm, resource allocation strategy, and other relevant scheduling policies.
- Handling Multiple Data Bearers
1. UE Configuration: Ensure that the UE is configured to support multiple bearers. This may involve setting up the UE with multiple PDU sessions, each representing a separate data bearer with its own QoS requirements.
2. gNB Configuration: Configure the gNB to handle multiple bearers for each UE, ensuring that the gNB is capable of managing and scheduling resources for each bearer independently.
- Retrieving Data for Each Bearer in `nrScheduler.m`
1. Bearer Identification: Within the `nrScheduler.m` file, you can retrieve data for each bearer by identifying the UE and the associated bearers. This may involve inspecting the incoming data packets and identifying the bearer to which each packet belongs.
2. Resource Allocation: Implement logic to allocate resources (e.g., time-frequency resources, power, etc.) for each bearer based on the scheduling algorithm and the QoS requirements of the bearers.
3. Scheduling Logic: Incorporate logic to schedule data transmission for each bearer based on the scheduler's decision, considering the specific requirements and priority of each bearer.
By following these steps and leveraging available resources, you can set up a simulation scenario with multiple data bearers for a single UE and customize the `nrScheduler.m` file to handle and retrieve data for each bearer according to your specific requirements.
Explore the MATLAB documentation for 5G toolbox or related communication systems toolboxes for specific examples and guidance on handling multiple bearers and customizing the scheduler logic.
