  This paper introduces the novel utility-oriented communications (UOC) concept
and identifies its importance for 6G wireless technology. UOC encompasses
existing communication paradigms and includes emerging human-centric and
task-oriented communications concepts. The authors investigate semantic
communications and semantic information transfer for vehicular metaverse as a
case study of UOC. Consider the Internet of Vehicles (IoV) users access
real-time virtual world updates from the base station (BS) wirelessly using
semantic communication, and an intelligent reflecting surface (IRS) is deployed
to impair co-channel interference. This paper formulates an optimization
problem where a novel utility expression for semantic communications is
incorporated. The proposed system model jointly considers latency and power in
wireless communication and the utility of semantic communication. The proposed
alternative optimization algorithm balances system efficiency and economics and
outperforms existing optimization algorithms under the same channel conditions.
