Abstract—In this paper, the two-user interference channel (IC) with specially correlated sources and channel state information (CSI), both in the sense of Slepian-Wolf (SW) is considered in which channel states are available at the encoders non-causally. In correlation structures in the sense of Slepian-Wolf, two correlated sources are modeled by three independent sources: a common source and two private sources. Therefore, we can call this channel as the IC with common message (ICC) and Slepian-Wolf CSI (ICC- SWCSI). We derive an achievable rate region for this channel by using rate splitting technique, superposition coding, binning scheme and jointly decoding; then we show that our rate region subsumes some related rate regions for the IC with or without non-causal CSI as its special cases.
