Job Description

Ericsson Research, Radio

Radio research are leaders in LTE and NR, we invent technologies for 5G and beyond enabling ubiquitous and efficient mobile broadband and machine-type communication. Key research areas are radio network solutions, radio access technologies, advanced antenna systems, propagation and wireless backhaul.

 

Background

The wireless smartphone success increases the demand to provide high bitrate. Apps and services are expected to be available wirelessly with the same experience as if provided over fiber. 5G systems are developed to support the networked society, with future mobile broadband, internet of things, as well as machine type communication both for performance critical industry use cases and for massive amounts of devices and sensors. To support this the 5G NR (New Radio) access has been designed to support a wide range of frequency bands with flexible configuration to be optimized for different services and deployments. Furthermore, 5G NR relies on directive beamforming for directing transmitted energy towards each user – a challenging yet important task. Beams can be based on a fixed Grid-of-Beams (GoB), or constructed through adaptive solutions such as reciprocity beamforming.

 

Thesis project description

The objective of this master thesis is to analyze radio measurements from 5G prototype systems, i.e. test-beds. Beam utilization and the performance of beam management shall be investigated, including (but not limited to) aspects such as Quasi-Co-Location (QCL), Beam Failure Recovery (BFR), and reciprocity beamforming. Undelaying radio measures such as signal strength, interference and channel conditions are analyzed. Possible feature improvements shall be suggested based on any new findings.

Qualifications

The successful applicant will be a self-motivated MSc student or equivalent with an interest in data analysis, algorithm development & testing. The work is research oriented, so ability to learn quickly, work independently and identify problems and solutions is necessary. You should be an MSc student, preferably in engineering physics, electrical engineering, computer science or similar. Courses in wireless communication theory and signal processing as well as experiences of communication systems and internet protocols are considered valuable merits. Analysis tools in Matlab will be designed, modified and used for tests and evaluations, which means that the thesis work requires good Matlab skills.

 

Extent

The position is for one student. Scope is 30 points (20 weeks). Please state in your application when you can start and attach the transcript of records.
