A user station for a bus system and a method for transmitting a message at different bit rates in a bus system. The user station includes a communication control unit for creating a message for a further user station of the bus system. The communication control unit provides, in the message, a first phase, which is to be transmitted at a first bit rate, and to provide a second phase, which is to be transmitted at a second bit rate, which is faster than the first bit rate. The communication control unit is designed to provide in the message a first predetermined bit pattern for a bit rate switching between the first and second bit rate and to provide a second predetermined bit pattern for a bit rate switching between the second and first bit rate. The second predetermined pattern differs from all other bit patterns in a valid message.
