Project Overview

• Project Name: 5G NR Module Benchmark and Analysis for Distinct Channel Models
• Student: Joao Albuquerque
• Mentors: Biljana Bojovic, Amir Ashtari, Gabriel Ferreira
• Google page: GSoC - Project
• Project Goals: Currently, ns-3 and the NR module provide an interface for using a channel model (3GPP). However, two other models have also been developed using the ns-3 environment: Two-ray and NYUSim. The project aims to integrate these two new models into NR module in a simplified and user-friendly manner. Furthermore, I will undertake additional tasks, such as testing the implemented code and creating an example that utilizes these implemented models.
• Repository: ns-3, NR
• About Me: I am an undergraduate student working at LASSE-UFPA, a telecommunications research laboratory, where I have been engaged in various projects using the ns-3 and nr. I have over a year and four months of experience working with ns-3 and the nr module, during which I developed applications, including a new ray-tracing module compatible with NR and the latest versions of ns-3. With this opportunity, I aim to make significant and definitive contributions to ns-3 and the NR module.

Milestones

You can track the project's plan by referring to this document: GSoC — Document Plan. The document will be constantly updated until the final submission.

Milestones for this project include updating the existing channel models in the ns-3, implementing a user-friendly interface via the nr module, and creating an example that utilizes all the added channel models within ns-3. The outline of these implementations will be separated into work packages (WPs) as follows:

WP 1 - NR interface for channel model usage (10 weeks)

• Task 1: Get familiar with BWP configuration, focusing on the channel model and how this configuration could be used from the NR helper class to initialize the BWPs. (0.5 week)
• Task 2: Get familiar with how the NYU channel model is being configured for the mmWave module in the NYU custom mmWave helper class. (0.5 week)
• Task 3: Prepare a refactoring plan for NR classes and check if the design will work for the three-channel models. (2 weeks)
• Task 4: Prepare 5G-Lena for different channel models that may not have spectrum channel matrix for su-MIMO and create a merge request to 5G-Lena. (4 weeks) [milestone 1]
• Task 5: Interface implementation for selecting the channel model via the NR helper class and creating a merge request for 5G-Lena. (3 weeks) [milestone 2]
  • Create a conditional build depending on the NYU channel model available in ns-3 and create a merge request to 5G-Lena. [milestone 3]
  • Extend NR helper to allow the configuration of 3GPP NTN channel models and create a merge request for 5G-Lena. [milestone 4]

WP 2 - Design and implement the benchmark scenario (8 weeks)

• Task 1: Identify and implement the appropriate scenario for all channel models. (1 week)
• Task 2: Prepare traces to be measured (e.g., entire simulation time, SINR, throughput, latency, etc.) and scripts for running and plotting based on the implemented example. (2 weeks)
• Task 3: Analyze, evaluate, and plot the results of the accomplished example. (3 weeks)
• Task 4: Extend the example to be used as a test and create a merge request of the implemented test to 5G-Lena; Write what was done in a blog post. [milestone 5] (2 weeks)

Weekly Report

Week 1 [May 31 - Jun 06 ]

• Finish the milestones
• Start to draft the desired implementation
• Start to study 5G-Lena and the modified MMwave helper classes

Week 2 [Jun 07 - Jun 13 ]

• Present a slide about BWP configuration and initialization [1]
• Create the first interface implementation (nr-helper) [scratch]
• Present a slide about the mmwave-helper class (modified to support nyu); start to define a plan for the first milestone and solve some doubts [2]

Week 3 [Jun 14 - Jun 20 ]

NOTE: We are still discussing the non-su-mimo implementation. For a more detailed explanation, go to GSoC - Document Plan

• The first approach for non-su-mimo channel model implementation, back to the 2.6 version see
• The second approach for implementing the non-su-mimo channel model involves creating a spectrum channel matrix for those without it see
• Start the interface implementation to enable the user to select distinct channel models using bandConf and initialization with nr-helper see
• Explain the NYUSIM channel model and compare it with 3GPP. Also, provide information about the interface implementation [3]
