The authors of [1] proposed a new synchronized delivery approach that uses trucks and multi-swarm unmanned aerial vehicles (UAV) for essential services in the 6G network. The proposed approach consists of determining the optimal placement of the trucks. Based on the placement of trucks, a certain number of UAVs can be deployed to assist the trucks by delivering products or performing essential services. The proposed environmentally friendly approach can reduce delivery time and road congestion.

The authors in [1] highlighted that significant financial burdens are imposed on major cities due to traffic congestion. In 2019, it was estimated that New York City incurred annual economic losses of $11.0 billion, while Los Angeles suffered losses of $8.2 billion. On average, each traveler wasted 140 hours and 103 hours annually in these cities due to congestion. Urban aerial mobility is poised to reshape the future of urban transportation by addressing and alleviating road transport congestion.

Flying and ground-based cars require various services such as autonomous driving, remote piloting, infotainment, and remote diagnosis. Each service requires specific Quality of Service (QoS) and network features. Therefore, network slicing can be a solution to fulfill the requirements of various services. Here, the authors proposed "Two-level Closed Loops for RAN Slice Resources Management Serving Flying and Ground-based Cars"
