Master Thesis: Positioning

Job Description

Date: Oct 17, 2019

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.

 

Background

Traditionally, positioning is a service added to an existing radio network deployment, for example to enable positioning of emergency calls. There is an interest in precise positioning as part of connectivity and communication services to industrial internet of things (IIoT). 5G can enable digitalization in industry use cases while ensuring robustness, interoperability and long-term support. There are numerous activities in standardization and in industry interest organizations to analyze and consolidate requirements from these use cases. Some use cases can comply with crude accuracy requirements, while other use cases require positioning accuracies in decimeters and very high availability.

Radio network deployment design involves placement of base stations, antenna height/direction/tilt, need of transport network between base stations and other network nodes, user distribution/behavior/services and much more.

The ambition with this master thesis is to analyze radio network deployment strategies in industry use cases in relation to accuracy and availability requirements and different positioning solutions. Industry use case radio channel models have been defined to better represent the radio propagation conditions in industry environments. Based on initial theoretical assessments of positioning performance, and simulations, the aim is to investigate deployment designs that can meet the strict positioning requirements.

 

Thesis Description

The following steps are envisioned as part of the thesis work:

  • Study theoretical positioning performance analyses in literature for a selected set of positioning solutions
  • Define an industry scenario in a simulation model with alternative network deployments
  • Analyze deployment strategies theoretically and in simulations to determine deployments that meet accuracy and availability requirements
  • Summarize the relation between accuracy and availability requirements versus suggested deployment strategies

The thesis will be concluded with a result presentation for the Ericsson research team.
