#MISSION SIX

XR (eXtended Reality) will enable many different new technologies and use cases that will improve communication, collaboration and virtual experience. In this challenge we would like you to focus on the Augmented Reality (AR) – Remote Assistance scenario, due to the several advantages and potential impact it can bring in the industry.

Imagine a user facing an issue on a complex device (located on country A) and requiring some expert support (located on country B) to fix it. In such a situation, a user could use an AR headset connected to its smartphone and start an AR-enabled video call with a remote expert. The remote expert will then be able to look at the system in real-time, guide the user during the debugging phase and help fixing the issue. However, enabling such a solution with a flawlessly AR call experience for both persons, requires addressing different technical aspects.

Therefore, we would like you to consider the following points and provide your solution ideas on how those aspects could be addressed.

• How would you measure QoE (Quality of Experience) on the Remote Assistance use case?
  • Which KPIs (potentially new) can you think of for measuring this?
  • Which application performance metrics would you consider?
  • How would you measure the Audio/Video experience?
• How would you measure the RF impact of body shadowing in the connection between AR headset and smartphone?
• How would you measure the channel performance and responsiveness?
  • How would you measure XR mobility (handovers/offloading) experience?
• How would you measure and visualize key device performance indicators (e.g. on the smartphone)?
• How would you design a solution that allows reporting live (during a Remote Assistance session) the XR device relevant KPIs to a network measurement equipment for evaluation and visualization?
  • Assume the AR call is running between the Smartphone/XR device and the network measurement equipment.

I am Paula Protocol and I am an expert in the 3GPP specifications for LTE, 5G NR and upcoming 6G, but I lack knowledge in programming and I am overwhelmed with the configuration options of the CMX500 communication tester.

My goal is to verify the proper function in regards to 3GPP protocols of the mobile radio chipset / smartphone developed by my employer.

The CMX500 is capable of achieving all my goals, but I just don't know how to use it.

Given the customers statement, the following questions arise.

Open Questions:

• Could we provide the customer with an AI based tool that assists in the creation of protocol tests?
• How would such a tool look like?
• How would you implement it and what resources do you need?

Background

There are protocols (3GPP) written down in natural language that determine explicitly what and how a feature in LTE, 5G, WLAN, etc. should be implemented and also be tested. The R&S CMX500 has the capability to execute all these test scenarios accordingly. There are multiple interfaces to configure the device and also setup test plans that incorporate test scenarios. For one there is the WebGUI and also a high level programmatic interface via the XLAPI Python Framework. One could also go low level and use the underlying client/server based RPC API for direct interactions.

The difficulty that arises is that the protocols are already vast and complicated in their nature. Adding the necessity to understand the workings and functionality of the CMX500 device makes the whole process much more complicated.

The available Human-Machine-Interfaces:

• WebGUI (http requests)
• Python API (XLAPI Framework)
• SCPI commands
• Low Level Client/Server based RPC API

• 3GPP (Source: 3GPP.org)

Background

We are excited to announce a student engineering competition focused on Integrated Sensing and Communication (ISAC), a cutting-edge technology that combines radar sensing and wireless communication into a single system. This competition is an excellent opportunity for you to showcase your engineering skills, creativity, and innovation in this exciting field.

The integration of sensing and communication has the potential to revolutionize various industries, including automotive, aerospace, healthcare, and industrial automation. We encourage you to select or suggest an application that has a high potential for a successful business case.

Identify a major technical challenge of the application and propose a feasible solution and define a set of key performance indicators (KPIs) that determines its performance.

At Rohde & Schwarz, with our expertise in wireless communication, radar technology, and signal processing, we are committed to advancing ISAC technology and its applications in all major industries. As a global leader in test and measurement, we offer a wide range of products and solutions that enable the development and deployment of ISAC systems. For example, our Automotive Radar Echo Generator (AREG) can emulate scenarios by modelling objects and targets in the DUT environment by manipulating the incident waveform in terms of attenuation, Doppler Shift and delay.

Task

• Choose your ISAC application
  Choose or come up with an ISAC application that you find particularly interesting and that you believe has the potential to bring significant value to a specific industry or scenario and describe how it works. Describe the required ISAC system and consider the technical, operational, and economic aspects.
• Identify a major technical challenge for this use case
  Describe a technical challenge related to your chosen ISAC application. This challenge could be related to the simulation, implementation, integration, or operation of the ISAC system.
• Define Key Performance Indicators (KPIs)
  Propose a set of relevant system KPIs. These KPIs should be relevant and measurable allowing for a clear evaluation of the ISAC system's performance encountering the described technical challenges.
• Develop a modeling approach and a measurement concept
  Develop models for the identified technical challenges.
  Propose a setup to emulate the most relevant scenarios. Describe the test setup including the necessary measurement instruments, simulation and software.
  Base your solution on available Rohde & Schwarz products and propose extensions if required

Your submission will be evaluated based on its technical merit, innovation, practicality and presentation.

Background

Reconfigurable Intelligent Surfaces (RISs) are treated as a key technology candidate for the next generation of mobile communications, 6G. These metamaterial-based surfaces, composed of a large number of unit cells, can dynamically manipulate the reflection properties of impinging electromagnetic waves. By intelligently adjusting the reflection coefficient (amplitude and phase) of each individual unit cell, the wireless propagation channel becomes controllable. With this, RISs are envisioned to enhance coverage without increasing the number of expensive and energy-intensive base stations. Moreover, use cases as for example physical layer security, interference suppression and capacity enhancement are discussed. Consequently, RISs support the steady increase in the overall network throughput of future wireless communication systems.

Task

How to develop a respective test environment for the evaluation of reconfigurable intelligent surfaces?

What are the most important key performance parameters to qualify RIS? How can a measurement setup look like to evaluate these parameters? Is your setup designed for near-field or far-field measurements and what are the consequences? Who are potential key customers for your test solution? What are the unique selling points of your idea? What are the limitations of your test setup?

Develop a test strategy to qualify RIS based on R&S antenna test systems and OTA chambers

"We divided the tasks among us so that everyone could contribute their best to the success of the team. Nevertheless, we discussed our approach to solutions, and you get inspired by your teammates' ideas. This has helped me a lot."

"One challenge is certainly, to work on demanding tasks under time pressure and create an attractive presentation. But it was a lot of fun for me to do it together with other students in a team."

"It is crucial to be able to assess one's own strengths and those of one's team memmbers properly and to focus under time pressure on the tasks one does best. And one must be able to quickly understand new subjects and apply them in practice. What did I like most? During the final round in Munich, there was still time to explore the city and get to know Rohde & schwarz better."
