Summary:An error frame shielding unit for a user station of a serial bus system and a method for communicating in a serial bus system are provided. The error frame shielding unit includes a shield decision block for generating a signal that indicates, during a transfer of a message on a bus of the bus system, whether or not a transmission signal, which has been created by the user station due to receiving the message, is to be transmitted onto the bus, and a transmission signal selection block for blocking the transmission signal, which via an error frame on the bus is to indicate a reception error in the message received from the bus as a function of the signal generated by the shield decision block, so that the error frame is not transmitted onto the bus.
