## 2 Conceptual Motivation  
The metaverse will leverage cutting-edge technologies, like blockchain, machine learning, network slicing, semantic web, computer vision, natural language processing, and wireless communication and networking [9], to examine and manage physical systems. The sixth-generation (6G) wireless system faces many previously unheard-of challenges, including ubiquitous connectivity, ultra-low latency, ultra-high capacity, reliability, and strict security, due to the strict requirements of the metaverse for a fully immersive experience, numerous concurrent users, and seamless connectivity [1]. Additionally, to ensure a high-quality user experience, wireless systems for metaverse applications must have high capacity and ultra-reliability, which cannot be achieved with the existing 5G technology. The 6G wireless communication revolution, which is expected to offer low latency, high throughput, and security services will, thus, be necessary in order to access the metaverse. As a result, 6G mobile communication is expected to revolutionize wireless networks and support a wide range of top-noth metaverse applications [10]. In [11], the authors proposed a revolutionary digital twin strategy that was supported by the metaverse by jointly taking into account the integrated model of communications, computation, and storage, utilizing mobile edge computing and very dependable and low latency communications. Most of the time, mmWave and THz transmissions operate in obstructed line-of-sight (LOS). Only when the beams of the receiver and transmitter are lined up can the communication be successful. Any small misalignment can cause the data stream from the metaverse services to stop [12]. In recent years, the communication community has devoted a lot of time to study intelligent reflecting surfaces (IRSs) [13]. In [10], the authors outlined an architecture for the metaverse geared towards a 6G system with a high possibility of using an IRS device. The impinging signal may be reflected by the IRS in the target direction. On the other hand, the IRS is made up of a large number of passive reflecting components that may intelligently alter the wireless propagation environment by adjusting the phase shifts. THz, IRS, and mobile edge computing (MEC) in [14] were utilized to enable VR systems in small inside spaces. High data speeds and dependable low latency are, therefore, guaranteed for smooth user connectivity. The architecture of an IRS is shown in Figure 2.  
The key features of an IRS can be implemented with a modest investment in hardware and minimal energy; this provides high-gain beamforming and serves as a backup link when a direct link is not available [15]. The 6G wireless networks offer an incredibly high data rate, great dependability, extensive worldwide coverage, minimal latency, high energy efficiency, and high reliability [16]. We demand more sophisticated network hardware as

According to recent academic publications, IRSs and terahertz communication are the key concepts for 6G [17; 18]. Thus, to achieve the goal of 6G, it is preferred to employ the IRS. Therefore, an IRS-assisted system can significantly impact high throughput and achievable rates in metaverse research for the next generation. In addition to wireless communication systems in metaverse scenarios, the implementation of an IRS-aided communication system may be a potential solution for achieving low latency and higher throughput systems. In [19], the authors proposed the unique utility-oriented communications (UOC) concept and discussed its significance for 6G wireless technology. In addition to incorporating newly developed human-centric and task-oriented communications principles, UOC embraces established communication paradigms. The authors used the vehicular metaverse as a case study of UOC to examine semantic communications and semantic information transfer for IRS-aided systems.
