Ultra Reliable Low Latency Communications (URLLC) in 5G: From Theory to Reality

5G is expected to support Ultra Reliable Low Latency Communications (URLLC) based services, such as industrial control, remote surgery, tactile internet, etc. These are also the most challenging services to implement because they require a new network design and control methodology, in order to satisfy their requirements and enable their co-existence with other types of services that 5G and beyond systems need to deliver. Indeed, today as we enter the Phase 3 of 5G design leading to 6G, it is imperative not only to understand how to deliver URLLC services but also to ensure that they will be offered in a sustainable fashion (i.e., not draining all network resources) that is compatible with the already provided enhanced Mobile Broadband (eMBB) services. The proposed tutorial addresses the signal processing and optimization aspects of URLLC for 5G and beyond networks. The tutorial will cover a novel system design framework, state of the art signal processing and optimization techniques; and introduce cross disciplinary methodology to discuss complex trade-offs in 5G and beyond networks in view of URLLC.
