“…However, this multi-Gbps opportunity is attracting new applications which are more dataheavy than bi-dimensional multimedia content: 5G will trigger the early adoption of AR/VR. Then, just like video-overwireless saturated 4G networks, the proliferation of AR/VR applications will deplete the 5G spectrum, and require a system capacity above 1 Tbps, as opposed to the 20 Gbps target defined for 5G [1]. Additionally, to meet the latency requirements that enable real-time user interaction in the immersive environment, AR/VR cannot be compressed (coding and decoding is a time-consuming process), thus the per-user data rate needs to touch the Gbps, in contrast to the more relaxed 100 Mbps 5G target.…”

“…Pervasive Connectivity: Mobile traffic is expected to grow 3-fold from 2016 to 2021, pushing the number of mobile devices to the extreme, with 10 7 devices per km 2 in dense areas (up from 10 6 in 5G) [1] and more than 125 billion devices worldwide by 2030. 6G will connect personal devices, sensors (to implement the smart city paradigm), vehicles, and so on.…”

“…Networks will need to transfer much greater amounts of data, at much higher speeds. Furthering a trend already started in 4G and 5G, sixth generation (6G) connections will move beyond personalized communication towards the full realization of the Internet of Things (IoT) paradigm, connecting not just people, but also computing resources, vehicles, devices, wearables, sensors and even robotic agents [1].…”

Reliable data connectivity is vital for the ever increasingly intelligent, automated and ubiquitous digital world. Mobile networks are the data highways and, in a fully connected, intelligent digital world, will need to connect everything, from people to vehicles, sensors, data, cloud resources and even robotic agents. Fifth generation (5G) wireless networks (that are being currently deployed) offer significant advances beyond LTE, but may be unable to meet the full connectivity demands of the future digital society. Therefore, this article discusses technologies that will evolve wireless networks towards a sixth generation (6G), and that we consider as enablers for several potential 6G use cases. We provide a full-stack, system-level perspective on 6G scenarios and requirements, and select 6G technologies that can satisfy them either by improving the 5G design, or by introducing completely new communication paradigms.

“…1, a typical 6G SATSI network contains four parts: a space network composed of interconnected satellites with different orbits; an air network contains high altitude platform like airplane [8], air ship, as well as low altitude UAV and flying BSs; a heterogeneous ultradense terrestrial network that includes core network (CN), cloud, edge, and M2M communication networks; a sea-based network that contains shortwave communication, ultrashort-wave communication, submarine optical network and underwater acoustic network that provide wireless connections to those equipments over the sea and underwater area. It is believed that terrestrial network will still be the most important part for providing wireless mobile services for most human activities [9].…”

To fulfill the requirements of various emerging applications, the future sixth generation (6G) mobile network is expected to be an innately intelligent, highly dynamic, ultradense heterogeneous network that interconnects all things with extremely low-latency and high speed data transmission. It is believed that artificial intelligence (AI) will be the most innovative technique that can achieve intelligent automated network operations, management and maintenance in future complex 6G networks. Driven by AI techniques, device-to-device (D2D) communication will be one of the pieces of the 6G jigsaw puzzle. To construct an efficient implementation of intelligent D2D in future 6G, we outline a number of potential D2D solutions associating with 6G in terms of mobile edge computing, network slicing, and Non-orthogonal multiple access (NOMA) cognitive Networking.

“…While the fifth generation (5G) communication has been expected to be utilized in various industrial fields, it is considered that a wider diffusion will be required as a type of further development in the future sixth generation (6G) era [1]. An extremely large number of Internet of Things (IoT) devices that collect images and sensing information of the real world are expected to spread further in the 6G networks, and an extremely large number of connections that are approximately 10 fold (10 million devices per square km) more than the 5G requirements are needed [2]. In addition to the approach of connecting a large number of IoT devices to a network, the IoT devices are expected to evolve to have functions for detecting the real world and collecting various sensory data intelligently [3].…”

In this paper, we consider an Internet of unmanned aerial vehicles (UAVs) over cellular networks, where UAVs work as aerial users to collect various sensory data, and send the collected data to their transmission destinations over cellular links. Unlike the terrestrial users in the conventional cellular networks, different UAVs have various communication requirements due to their sensing applications, and a more flexible communication framework is in demand. To tackle this problem, we propose a UAV-to-Everything (U2X) networking, which enables the UAVs to adjust their communication modes full dimensionally according to the requirements of their sensing applications. In this article, we first introduce the concept of U2X communications, and elaborate on its three communication modes. Afterwards, we discuss the key techniques of the U2X communications, including joint sensing and transmission protocol, UAV trajectory design, and radio resource management. A reinforcement learningbased mathematical framework for U2X communications is then proposed. Finally, the extensions of the U2X communications are presented.2) UAV Transmission: After UAV sensing, the collected data will be transmitted to the corresponding BS or UE, which is defined as the transmission destination. For each UAV, the transmission channel model and frequency band are regulated by the 3GPP [23]. To satisfy the transmission requirements raised by various applications, we provide three communication modes for the UAVs, namely U2N communications, U2U communications, and U2D communications. The communication mode for each link is selected by the UAV according to its location and the communication requirements of the sensing application. The descriptions of these three communication modes will be elaborated on in Section II-B.
