UAVs are becoming an emerging technology with several civil applications, including remote delivery of goods, environmental monitoring, and support to emergency scenarios, among others. This lecture will address the different options for integration of UAVs with "beyond 5G" mobile networks, outlining potential 6G use cases in the integration of such agile mobile platforms within the architecture of future mobile networks. The first part of the presentation will offer an overview of ongoing activities and relevant efforts in the field, while the second one will provide a look into the future of UAVs in 6G.
