Reconfigurable intelligent surface (RIS) is a recently emerging transmission technology for application to wireless communications. Regarded to be an emerging solution for the next generation of communications, RIS is a nearly passive device that realizes smart radio environment with low hardware cost and energy consumption. This merit of RIS, on the other hand, imposes a major challenge to the channel estimation of RIS-aided communication systems. Recently, many protocols and algorithms are proposed to handle this challenging problem. In this chapter, we review the problem of channel estimation in RIS-aided systems and survey recent developments on this topic.
