Abstract：A class of state-dependent relay channel with orthogonal channels from the source to the relay and from the source and the relay to the destination is studied. The two orthogonal channels are corrupted by a common channel state which is known to both the source and the relay non-causally. Based on superposition coding, cooperative GP (Gel’fand-Pinsker) coding and PDF (Partial-Decode-and-Forward) relaying, the lower bound on the capacity for this channel is established firstly. Then, for the semi-deterministic relay channel with orthogonal components whose receiver output is a deterministic function of the relay input, one of the source inputs and the channel state, the explicit capacity is characterized exactly.
