abstract: Utilizing reconfigurable intelligent surface (RIS) technology to construct an intelligent radio environment is essential for the development of the sixth-generation (6G) communication network which is marked by ultra-high speed, minimal latency, and extensive connectivity. Therefore, to further enhance the coverage and signal quality of wireless communication systems, we investigate an active RIS-assisted rate-splitting multiple access (RSMA) system. Specifically, we investigate the effect of relevant parameters on system performance by deriving the analytical expressions for the outage probability (OP) of users employing hybrid automatic repeat request (HARQ) transmission strategy. The numerical results show that: 1) The reliability of the system is improved by combining HARQ transmission strategy. 2) The increase in the number of reconfigurable elements also significantly enhances the stability performance of the considered system.
