  6G-enabled edge intelligence opens up a new era of Internet of Everything and
makes it possible to interconnect people-devices-cloud anytime, anywhere. More
and more next-generation wireless network smart service applications are
changing our way of life and improving our quality of life. As the hottest new
form of next-generation Internet applications, Metaverse is striving to connect
billions of users and create a shared world where virtual and reality merge.
However, limited by resources, computing power, and sensory devices, Metaverse
is still far from realizing its full vision of immersion, materialization, and
interoperability. To this end, this survey aims to realize this vision through
the organic integration of 6G-enabled edge AI and Metaverse. Specifically, we
first introduce three new types of edge-Metaverse architectures that use
6G-enabled edge AI to solve resource and computing constraints in Metaverse.
Then we summarize technical challenges that these architectures face in
Metaverse and the existing solutions. Furthermore, we explore how the
edge-Metaverse architecture technology helps Metaverse to interact and share
digital data. Finally, we discuss future research directions to realize the
true vision of Metaverse with 6G-enabled edge AI.
