Master Thesis – 4G evolution
Background
Mobile broadband for cellular networks are continuously being evolved to meet the future demands for higher data rates, improved coverage and capacity. The enormous success of Smart Phones, tablets and dongles boosts mobile broadband date requirements. 4G, or Long Term Evolution (LTE) is commercially deployed since 5 year back, and is being evolved by Ericsson and others in 3GPP standardization body. LTE brings radio features such as advanced uplink and downlink multi antenna solutions (MIMO) and larger bandwidths from aggregating multiple carriers. These and other features will bring peak rates of 1 GB/s, but also improves other characteristics such as coverage, delay and flexibility.
Thesis Description
LTE is being specified by vendors and operators in 3GPP. Work with Release 13 of LTE has just started up and is now being defined by Ericsson and others. Candidate features for release 13 are:
More advanced base station antenna transmissions like forming the beam in the vertical dimension as well, and more advanced Multi-user MIMO (i.e. sending to multiple users at the same time and frequency)
Energy saving methods for machine type of terminals, which need to cope with a small battery which cannot be replaced too often.
Methods for enhanced coverage, in particular for machine type of communications, when the sensors and machines may very well be in bad coverage locations like basements and rural areas.
Latency reductions in order to reducing packet delays and increase user bit rates
The thesis work will include algorithm design in some of these areas together with Researchers here at Ericsson Research in Linköping, LTE cellular system simulation evaluations, and investigating the impact on end user performance as well as system capacity.
Qualifications
This project aims at Master of Science students in electrical engineering, computer science, or computer engineering.
Matlab and/or Java are our primary software languages for modelling and simulation work, so excellent Matlab and/or Java knowledge and programming skills is a must. Background in tele-communication is preferred. Applicants with less than B/4.0 in average grade will not be considered.
Preferred starting date January 2015.
Keywords
