Abstract: In this paper, we introduce a discrete memoryless State-Dependent RelayChannel with Private Messages SD-RCPM as a generalization of thestate-dependent relay channel. We investigate two main cases: SD-RCPM withnon-causal Channel State Information CSI, and SD-RCPM with causal CSI. Ineach case, it is assumed that partial CSI is available at the source and relay.For non-causal case, we establish an achievable rate region usingGel-fand-Pinsker type coding scheme at the nodes informed of CSI, andCompress-and-Forward CF scheme at the relay. Using Shannon-s strategy and CFscheme, an achievable rate region for causal case is obtained. As an example,the Gaussian version of SD-RCPM is considered, and an achievable rate regionfor Gaussian SD-RCPM with non-causal perfect CSI only at the source, isderived. Providing numerical examples, we illustrate the comparison betweenachievable rate regions derived using CF and Decode-and-Forward DF schemes.
