# 6G Use Cases and Scenarios: A Comparison Analysis Between ITU and Other Initiatives
###### Abstract  
In the next decade, the amount of network traffic is estimated to reach Zettabytes. The future International Mobile Telecommunications-2030 (IMT-2030) standard of mobile networks, known as 6G, introduces an important paradigm shift in the context of wireless communication systems thanks to capabilities such as low latency and high data rates. Official documents on 6G standardization have been released by the International Telecommunication Union (ITU). However, other visions and use cases of 6G have been proposed by industrial stakeholders and research institutions, thus generating a multitude of use cases and usage scenarios that are only apparently different from each other. This paper would contribute to providing a holistic vision of the 6G-enabled use cases and potentially impacted vertical market sectors. The differences and similarities between what has been proposed by ITU and other initiatives are identified through a comparison based on the technological characterization of use cases and of the considered vertical market sectors. The main findings presented in this paper demonstrate that many of the use cases proposed by ITU and by the other initiatives are almost identical in many cases.

operating with 5G, and its scope is to provide research and development contributions to the 6G system. The Next G Alliance (NGA) is a research initiative carried out by US industries and research institutions aiming to identify potential opportunities and impacts generated by the introduction of 6G. The Next-Generation Mobile Network (NGMN) Alliance is a forum joined by the most important worldwide mobile network operators (MNOs) and industry stakeholders in the mobile communication sector. The NGMN started to identify the major opportunities provided by the future 6G system. After an in-depth analysis of the ITU official documents and the other considered initiatives on 6G, we have seen a \"disordered\" proliferation of other scenarios and visions on 6G. This could lead to confusion in readers due to the fragmentation of ideas among ITU and other initiatives. This is evidenced by the different descriptions of seemingly similar scenarios in terms of objectives, technologies, applications, etc. Another important element we consider in this paper concerns the interests and developments of the vertical market sectors in which 6G will find application and a potential impact. Below, we first aim to understand whether the use cases and scenarios proposed by ITU and the other initiatives, even though described differently, could instead be considered similar in terms of their main enabling technologies and the services/applications required for the implementations. Thus, one of the main goals of this paper is to search for analogies and to evidence differences among the proposals from 6G initiatives and ITU. A similar analysis will be conducted for some reference vertical market sectors we have selected in this paper. In particular, we try to understand whether the objectives of the vertical market sectors can be categorized from a technological point of view (similarly to what has been carried out for the use cases and scenarios) and also if the studies and standardization activities promoted by ITU and other initiatives can cover the needs of the main vertical market sectors. The analysis method introduced in this paper allows us to assess the similarities and differences between the use cases and the scenarios proposed by ITU and the other initiatives. The direct analysis and comparison of use cases starting from the available documents is impossible in practice and useless. Every initiative adopts its terminology and conventions to describe use cases and scenarios. For this reason, in our analysis, we have introduced an objective reference to carry out the comparison.
