Description

Title
“Radio Resource Management Techniques for Ultra-Reliable Low-Latency Communications in Unlicensed Spectrum”

Abstract
Supporting delay-critical communications with very high reliability plays a crucial role in the context of Industry 4.0. The fifth-generation (5G) of cellular technologies emerges as a solid enabler due to its potential in supporting ultra-reliable and low-latency communications (URLLC). Unlicensed spectrum is seen as an attractive option for industrial verticals due to its easy access and global availability, as well as its simplicity and low cost of deployment as compared to licensed spectrum. However, the strict spectrum regulations impose additional challenges in fulfilling the URLLC requirements in unlicensed bands.

The PhD analyzes the capabilities of unlicensed radio access technologies in supporting communications with stringent latency and reliability requirements. Novel radio resource management techniques and mandatory channel access procedures are investigated. The PhD project answers research questions such as: What is the impact of channel access mechanisms on the overall system performance? Which latency-reliability requirements can be fulfilled by cellular radio access technologies operating in the unlicensed spectrum? Which RRM and channel access enhancements are promising for supporting Industry 4.0 use-cases? Which recommendations to follow in hostile deployments with unplannedinterference?
