D2.1 Scenario description and initial requirements

This document introduces the outcomes of the initial use cases description and requirements elicitation work carried in the H2020 DEDICAT 6G project. The overall objective of this project is to design a smart connectivity platform that is green, highly adaptive, ultra-fast, and dependable/resilient for securely supporting innovative, human-centric applications that will be validated in representative use cases. For this, DEDICAT 6G will address techniques for efficient dynamic connectivity extension and intelligent resources placement in the mobile network, through the exploitation of novel mobile client nodes, with the required secure and trusted exchange of information.

This document provides a detailed definition of the DEDICAT 6G use cases. Each use case perfectly matches the project’s technical objectives while being relevant both from a social as well as a financial point of view. Therefore, they have been selected to test, demonstrate, and validate the solutions that will be developed during the project. Multiple stories are depicted for each use case to illustrate the expected workflow using the DEDICAT 6G platform and identify various ways for stakeholders to interact with each other.

Four use cases are proposed in DEDICAT 6G:

1. Smart warehousing: It covers the trustworthy automated real-time monitoring, surveillance, and optimized operation of a warehouse through utilization of automated guided vehicle (AGV) for improving operations such as picking sequence and quality assessment of products. It has a strong emphasis on real-time human machine interaction, computation offloading and security.
2. Enhanced experiences: It provides live streaming applications that use enhanced data overlay in 360° and augmented reality (AR) applications as well as more complex datasets in virtual reality (VR) with the needed hard requirements in terms of bandwidth and computing capabilities for heavy video processing and distribution. This use case is focused on distributed intelligence, computation and caching offloading, and dynamic coverage extension.
3. Public safety (Public Protection and Disaster Relief, PPDR): This aims to showcase how resilience of critical communications can be enforced through DEDICAT 6G solutions and how human security can be protected in extreme situations such as natural disasters or terror attacks by the use of diverse assets (drones, AGVs, etc.). This use case is concentrated on intelligence distribution, dynamic coverage extension, security guarantee, and human in the loop.
4. Smart highway: It describes how connected and autonomous mobility can benefit from beyond 5G (B5G) and 6G connectivity, especially in the area of efficiently offering the smallest possible delay and ultra-reliability. It is related to intelligence distribution, computation and caching offloading, dynamic coverage extension, safety, and human in the loop.

DEDICAT 6G use cases are presented from the standpoint of several relevant actors, contextualized in every use case business field. Gaps are identified, and a set of requirements considering existing technologies and trends are extracted. Finally, proposals on how to fill these gaps are discussed, envisioning the expected functionalities of the DEDICAT 6G platform.

This deliverable provides the basis for the design and implementation of technical innovation work that will be performed in multiple work packages: WP2 where the architecture will be detailed and WP3, WP4, WP5 where the key DEDICAT 6G technical enablers will be designed and developed and WP6 where performance evaluation and validation through demonstrations of DEDICAT 6G architecture and solutions will be accomplished.
