  With the great success of artificial intelligence (AI) technologies in
pattern recognitions and signal processing, it is interesting to introduce AI
technologies into wireless communication systems. Currently, most of studies
are focused on applying AI technologies for solving old problems, e.g.,
wireless location accuracy and resource allocation optimization in wireless
communication systems. However, It is important to distinguish new capabilities
created by AI technologies and rethink wireless communication systems based on
AI running schemes. Compared with conventional capabilities of wireless
communication systems, three distinguished capabilities, i.e., the cognitive,
learning and proactive capabilities are proposed for future AI wireless
communication systems. Moreover, an intelligent vehicular communication system
is configured to validate the cognitive capability based on AI clustering
algorithm. Considering the revolutionary impact of AI technologies on the data,
transmission and protocol architecture of wireless communication systems, the
future challenges of AI wireless communication systems are analyzed. Driven by
new distinguished capabilities of AI wireless communication systems, the new
wireless communication theory and functions would indeed emerge in the next
round of the wireless communications revolution.
