<p>Although
Cooperative Communications (CC) already exists in 4G LTE/5G, performance
improvement is just not enough, hence, how to apply collaborative technology in
6G to achieve Internet of Everything and improve communication quality
significantly is one of most important issues. As 5G communications standard has
gradually established recently, CC has been one of most
critical communication technologies which plays a founding role on Internet of Everything
in 6G networks.
Thus, in this study we propose new 6G enabled ultra-massive Machine Type Communication (mMTC) framework
based on space-ground integrated networks, and consider that collaborative
ideology has been regarded as foundation theory which widely exists in future multiple
hybrid scenarios, such as, Cognitive-Internet of Things (C-IoT) networks, UAVs
(Unmanned Aerial Vehicles) communications, air-space-ground integrated networks,
underwater acoustic communication and so on. Besides, we discuss other key
communication technologies that are closely combined with unique communication
scenes, and elaborate critical problems that shall be solved in 6G ultra-mMTC Internet
of Everything networks. Furthermore, we discuss extreme low-complexity and fast
ultra-massive relays selection algorithm to apply in all sorts of future 6G scenarios.
At last, it is concluded that for arbitrary two communication points (source/destination
devices, sensors, relays, IoT nodes and so on), ideology of nodes selection of collaborative
communication is theory of foundation to realize and optimize communication
transmission in 6G Internet of Everything ultra-mMTC networks. </p>
