  Recently, significant research efforts have been initiated to enable the
next-generation, namely, the sixth-generation (6G) wireless systems. In this
article, we present a vision of metaverse towards effectively enabling the
development of 6G wireless systems. A metaverse will use virtual representation
(e.g., digital twin), digital avatars, and interactive experience technologies
(e.g., extended reality) to assist analyses, optimizations, and operations of
various wireless applications. Specifically, the metaverse can offer virtual
wireless system operations through the digital twin that allows network
designers, mobile developers, and telecommunications engineers to monitor,
observe, analyze, and simulations their solutions collaboratively and
virtually. We first introduce a general architecture for metaverse-based
wireless systems. We discuss key driving applications, design trends, and key
enablers of metaverse-based wireless systems. Finally, we present several open
challenges and their potential solutions.
