Master Thesis – 5G Radio Access
Background
Mobile broadband for cellular networks are continuously being evolved to meet the future demands for higher data rates, improved area coverage and system capacity. However, this evolution is just the start of a transition into a fully connected Networked Society, providing access to information and sharing of data anywhere and anytime for anyone and anything. Thus, in the future, wireless access will not only be about connectivity for people, but also about connectivity for any kind of entity that benefits from being connected.
It is expected that the next-generation, 5G, mobile communication systems will be commercially available after year 2020. The global research efforts are already ongoing in all continents, including, for example, the METIS EU project.
New scenarios, not fully addressed by current cellular systems, such as massive deployment of ultra-low power sensors, intelligent traffic systems, critical low-latency communications, enterprise networks, etc. are of interest for 5G.
Thesis Description
This thesis work will investigate the system performance from introducing technical components that are likely to be a part of future 5G radio access. Examples of such components are
- Multi-user MIMO (sending to multiple users with many antennas at the base station), and antenna beam forming - Full duplex (transmitting and receiving at the same time on the same frequency)
- Ultra-short transmission block lengths and quicker hand-shaking protocols in order to have shorter packet delays
- Shared or unlicensed spectrum usage (wireless communication on spectrum that are shared between operators or is open for all)
- Etc…
The thesis work will include algorithm design together with Researchers here at Ericsson Research in Linköping, 5G cellular system simulation evaluations, and investigating impact on end user performance as well as system capacity and radio network energy efficiency.
Qualifications
This project aims at Master of Science students in electrical engineering, computer science, or computer engineering.
Matlab and/or Java are our primary SW languages for modeling and simulation work, so excellent Matlab and/or Java knowledge and programming skills is a must. Background in telecommunication is preferred. Applicants with less than B/4.0 in average grade will not be considered.
Extent
The project is intended for one MSc student.
Preferred starting date January 2015
