PhD Thesis Title: Dynamic Scheduling for Ultra Reliable and Low Latency Communication

The new technologies under the fifth industrial revolution change the wireless communication methods. Compared with traditional network services, the processing of signal transmission can be improved in terms of the signal latency, reliability and transport efficiency. Therefore, it brings unprecedented services and more convenient lifestyle, such as pilotless automobile, drone-based deliveries, smart cities etc. To implement above requirements, International Telecommunication Union (ITU) has stated three categories of further 5G services: ultra-reliable and low-latency communication (URLLC), massive machine-type communication (mMTC), and enhanced mobile broadband (eMBB). According to 3rd Generation Partnership Project (3GPP), the URLLC traffic needs to transmit small payload with a low latency within 1ms and at least 99.999% success probability.

On the other hand, the 5G services also requires a high peak data rate for eMBB users, high connection density and energy efficiency for mMTC traffic. Specifically, eMBB traffics are served on most frequency bands, while the URLLC should be accommodated instantaneously. Therefore, the joint scheduling for the coexistence system of URLLC and eMBB on the same radio spectrum is important and difficult. This research focuses on the design and analysis of optimized scheduling algorithms to enable URLLC requirements when it coexists with eMBB services.
