In this study, the three‐user interference channel (IFC) with common information is considered, where each receiver decode not only the private message from the intended transmitter but also the common messages from the non‐intended transmitters by applying a simultaneous decoding scheme. An achievable rate region is presented using rate splitting and superposition encoding at the transmitters and simultaneous joint decoding at the receivers in which the transmitters cooperatively send the split messages which allows the interference cancellation at the receivers. The implicit form of the achievable rate region is also extended to K ‐user IFC with common information. Finally the inner bound derived for the three‐user discrete memoryless IFC with common information is generalised to the Gaussian case and is evaluated in a numerical example.
