Cooperative Diversity Mechanisms for Critical Machine-Type Communications
The goal of this thesis is to study different enablers for IIoT, discuss their associated challenges, research directions, and specifically focus on diversity mechanisms as a potential enabler for URLLC services in the factories of future.
The first part of this thesis provides an overview of potential enablers to meet URLLC requirements. We discuss the corresponding merits and challenges of each technique, and their relevance to IIoT is highlighted. Thereafter, we survey cooperative diversity mechanisms to enable URLLC applications, and meet their corresponding requirements.
The second part focuses on the performance analysis of URLLC via cooperative diversity techniques. Different performance metrics such as reliability, latency, and energy efficiency are studied, and the impact of different parameters such as coding rate, transmission power, pilot power/length, blocklength, and resource allocation under a hard deadline on system performance are examined. We aim to mathematically model and characterize the trade-offs between reliability and latency requirements.
Finally, the last part of the thesis looks beyond the cooperative diversity technique to enable URLLC services for future connectivity.
