| 520 | 3 | |a In traditional Reconfigurable Intelligent Surfaces (RIS) systems, the RIS is mounted on stationary structures like buildings, walls, or posts. They have shown promising results in enhancing the performance of wireless systems like capacity and MSE in poor channel conditions. The traditional RIS is a monolithic structure containing a large number of reflecting elements (passive or active). In this paper, we propose the idea of mounting a small number of RIS elements (usually between 2 to 4 ) on user equipment (UEs) like mobile phones, laptops, and tablets, to name a few. A joint coordinated optimization of phase shifts of all the passive RIS elements on the participating UEs is envisioned to enhance the performance of wireless communication between an intended transmitter and receiver in the MSE sense. Given that the RIS elements are mounted on the UEs, the challenging channel estimation problem with RIS is significantly simplified. For the case when there is a line-of-sight (LOS) channel and with a large number of participating RIS-mounted UEs, the LOS is converted into a multipath-rich-scattering channel even for millimeter wave and Terahertz operating ranges that enable higher spatial multiplexing gains, thereby significantly improving the MSE performance compared to traditional RIS channels. We support the above claims using simulations. | |
