摘要：
This paper proposes a reconfigurable intelligent surface (RIS) assisted scheme to mitigate cross-link interference (CLI) in the dynamic time division duplex (TDD) wireless communication system. The proposed scheme designs the weights of RIS elements by reconstructing the equivalent channel matrix. Besides, we efficiently reduce the overhead by predicting the channel state information (CSI) between the user equipment (UE) and the RIS. Simulation results show that the proposed RIS-assisted scheme can effectively mitigate the CLI, and it can achieve a better bit error rate (BER) performance than the benchmark schemes. By employing the predicted CSI, the proposed RIS-assisted scheme can also maintain a good BER performance.
