Edge artificial intelligence in 6G systems: Theory, key techniques, and applications

As the permeation of artificial intelligence (AI) in wireless applications, some data-driven and computing-intensive services are emerging, such as mobile high-definition AR/VR, and real-time fingertip interactions. Moreover, the application scenarios have been extended to penetrate the vertical industry, which have multi-dimension and diverse quality of service (QoS) requirements. Recently, the research and the development of 6G have been triggered, and much higher QoS requirements of data rate, latency, and connectivity will be raised.
