N2 - Multibeam satellite system (MSS) has become the trend because of its ability to provide seamless information services. However, co-frequency interference between beams significantly deteriorates communication performance. Existing interference management schemes regard MSS as multi-antenna systems and introduce precoding technology to eliminate interference, ignoring the characteristics of beam gain and the limited computing resources of satellites. Motivated by this, we design an adaptive grouping access scheme based on the promising ratesplitting multiple access to mitigate inter-beam interference. We initiate our discussion by formulating the weighted sum rate (WSR) maximization problems and deploying an enhanced alternating optimization strategy to navigate through these intricate non-convex issues. The efficacy and reduced complexity of our suggested approach are validated through simulation outcomes.
