Keynote Title: Harvesting Diversity for Ultra-Reliable Wireless Communications
Abstract: Ultra-reliability is a crucial requirement for wireless communications in industrial automation applications. This talk will give an overview of several key techniques to harvest diversity for enhancing the reliability. Consider a typical task of transmitting a short message from a controller to several actuators in an industrial plan -- all within stringent delay and reliability constraints. A key protocol is to aggregate the user messages as a single packet and to broadcast it to multiple receivers. This allows the use of multi-hop relaying for harnessing spatial location diversity, incremental redundancy for providing coding diversity, and device-to-device communication for harvesting cooperative diversity for achieving ultra-reliability. We will also discuss the role of successive interference cancellation vs. interference avoidance in a multicell setting.
