  The concept of the Metaverse aims to bring a fully-fledged extended reality
environment to provide next generation applications and services. Development
of the Metaverse is backed by many technologies, including, 5G, artificial
intelligence, edge computing and extended reality. The advent of 6G is
envisaged to mark a significant milestone in the development of the Metaverse,
facilitating near-zero-latency, a plethora of new services and upgraded
real-world infrastructure. This paper establishes the advantages of providing
the Metaverse services over 6G along with an overview of the demanded technical
requirements. The paper provides an insight to the concepts of the Metaverse
and the envisaged technical capabilities of 6G mobile networks. Then, the
technical aspects covering 6G for the development of the Metaverse, ranging
from validating digital assets, interoperability, and efficient user
interaction in the Metaverse to related security and privacy aspects are
elaborated. Subsequently, the role of 6G technologies towards enabling the
Metaverse, including artificial intelligence, blockchain, open radio access
networks, edge computing, cloudification and internet of everything. The paper
also presents 6G integration challenges and outlines ongoing projects towards
developing the Metaverse technologies to facilitate the Metaverse applications
and services.
