“…can provide an improved end-user experience with enhanced 29 coverage and spectral efficiency. Therefore, numerous studies 30 have been conducted on mmWave beamforming systems [1], 31 [2], [3], [4], [5], [6], [7], [8], [9], [10], [11]. 32 However, the coverage hole problem in a non-line-of-33 sight (NLOS) environment remains difficult to solve, even 34 with the advanced beamforming technologies of 5G FR2 35 bands, as explained below.…”

10 11 12 13 the coverage hole problem was a reconfigurable intelligent 57 surface (RIS). A RIS, defined as an actively controlled meta-58 surface, can provide alternative wireless propagation paths 59 when new ones are required, as shown in Fig. 1. When 60 obstacles block the line-of-sight paths between the base sta-61 tion and user equipment, alternative paths can be provided 62 to users in the blocked area via the reflected signal at the 63 RIS. The RIS consists of uniformly distributed reconfigurable 64 unit cells with integrated switching devices (or components).
