Ericsson Research                
Ericsson Research develops new communication solutions and standards. The organization has responsibility to provide Ericsson with world-class system concepts, technology innovations, and methodologies. The rapidly increasing demands for mobile broadband access in combination with needs for new technology and solutions for the digitalization of industries and societies creates challenging and exciting opportunities for our organization. Building on our experience from real network operations, profound knowledge about existing standards, and forward-looking research, we invent and master advanced concepts and solutions that shape today’s and tomorrow’s mobile radio communication.


Job Description
We are looking for a highly motivated student for a simulation study of Radio Network energy performance. The recently standardized 5G system offers many possibilities to save energy by reducing the power consumption in both the user equipment and in the radio base station. How do we best harvest these possibilities, and enable the most efficient network? Since many different aspects (e.g. Discontinued Transmission (DTX) and hardware sleep states, heterogeneous network deployments, high traffic load urban or low traffic load rural scenarios etc.) contributes to the total power consumption the problem is best studied with a network system simulator. This thesis work should therefore focus on implementing power-saving algorithms and scenarios in a java-based simulator, running evaluation studies and analyzing the results.


In our unit at Ericsson Research, Network Architecture and Protocols, we have the mission to develop and drive best-in-class procedures, protocols and architecture solutions for current and future wireless access networks and mobile systems.


You, as the successful candidate for the role:

  • will be working in an international team of world-class researchers with different backgrounds and experiences and including some of the key authorities and thought leaders world-wide on mobile communication,
  • will have the opportunity to gain expertise in wireless systems making you an attractive candidate also for other parts of the company, including possibilities for an international career,
  • will work with highly skilled and creative colleagues,
  • will work in a dynamic and cross-functional department where there will be opportunities for continuous learning and growth, trying out new roles and responsibilities, impacting ways of working, and much more.


Your qualifications:

  • Student with at least 3 years studies in Wireless Communications, Electrical Engineering, Engineering Physics, Computer Science, or similar technical field.


Your abilities:

  • Strong analytical skills, eagerness to find innovative solutions to complex problems.
  • Strong interest in digital and wireless communications and of cellular systems design, in-depth understanding is a plus.
  • Good programming skills (java and Matlab) and experience in running computer simulations.
  • Rich in initiative, creative, and with strong personal drive and commitment.
  • Excited to work in an environment where you cooperate closely in a diverse team, together striving to fulfil common targets.
  • Good in communication and finding it easy to express and demonstrate your findings and knowledge to others, orally as well as in writing.
