| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Intelligent reflecting surface (IRS), which enables control of propagation characteristics, has attracted attention as a technology that can greatly improve energy use efficiency in 6th generation mobile communication systems. In order to design the phase shift for each reflective element of IRS, it is necessary to obtain the channel information for all elements. However, this process is not realistic because the overhead is too large. In addition, when multiple carriers share an IRS for communication, setting the phase shift according to a specific carrier may have a negative impact on other carriers. We have proposed a wireless communication system using standalone IRS to solve these problems. We have also already proposed a method to achieve wireless resource allocation optimization in the proposed system using quantum computing. Furthermore, we have already demonstrated the effectiveness of the proposed method in a single-carrier environment. In this report, we show the effectiveness of the proposed method in an environment where IRS is shared by multiple carriers, using the results of computer simulations. | |
