Job description

Job Description:Impact of TN/NTN spectrum sharing in non-terrestrial networks (NTN)
Final year of engineering school or Master2 level
Duration: 6 months
Starting Date: March or April 2025
Location: Ericsson R&D center Massy, FranceEricsson is building a new R&D team in Massy, France, covering many cutting-edge technologies such as AI/ML, cloud, and 5G and beyond technologies. Within this new lab, Standards & Technology unit, is part of Business Unit Network’s global Standards & Technology organization. At Business Unit Networks, Standards & Technology secures technology leadership in Radio Access Networks (RANs) by actively driving New Concepts, Standardization, SW- and HW Research, Architecture and Testbeds. Technical focus includes 5G evolution, IoT, Digital twins, Automation / Machine Learning and Security.As a part of this new young and talented team of researchers, we are looking for the next year interns that will help us grow and engage in our activities on non-terrestrial networks (NTNs). Mobile communication over NTNs has drawn a lot of attention in both academia and industry, for example it has been a focus area in 3GPP since Rel-15. For the moment, attention is given to satellite communications and, more specifically, low earth orbit (LEO) deployments, which provide a relative better link budget compared to medium (MEO) and geostationary (GEO) earth orbit constellations.As frequency band is a scarce resource in wireless communications, NTN systems will encounter co-channel or adjacent frequency band sharing situation with existing terrestrial networks (TNs). As a result, interference from one network (known as aggressor) to the other (known as victim) becomes critical to the victim network’s system capacity, throughput performance of UEs especially in border region of the two networks. This internship will focus on the TN-NTN coexistence scenario where NTN is the victim and TN is the aggressor. The candidate will 1) build a TN-NTN coexistence simulation scenario of NTN with LEO constellation as the victim and TN as the aggressor, 2) evaluate the performance of the NTN system, 3) study and implement various interference mitigation methods applied to either NTN or TN, 4) propose and assess new approaches to improve NTN performance in TN-NTN co-existence scenario, possibly also compliant with 3GPP protocols. The expected results may lead to writing an academic publication or filling a patent for an invention.

To be successful in the role you need to have

• Strong background in wireless communications and mathematics.
• Good understanding of TN/NTN spectrum, interference mitigation techniques. Knowledge of 3GPP protocols is a plus.
• Proven experience with MATLAB and other similar simulation tools.
• Familiar with system-level and link-level simulations.
• Qualities of fast learning, critical thinking, autonomy, and teamwork.
• Fluent English language skills in both writing and conversation. French language skills are a plus.

Interns:Interns who join us will enjoy an outstanding chance to make connections, to make change, to make a real difference. We are always looking for interns to become permanent members of our Ericsson team, so you’ll have the opportunity to discuss your future with us during your internship.What happens once you apply?to find all you need to know about what our typical hiring process looks like. This may vary depending on the location and role.Encouraging a diverse and inclusive organization is core to our values at Ericsson, that’s why we nurture it in everything we do. We truly believe that by collaborating with people with different experiences we drive innovation, which is essential for our future growth. We encourage people from all backgrounds to apply and realize their full potential as part of our Ericsson team.
