A communication control device for a user station. The communication control device controls a communication of the user station with at least one other user station of the bus system, and generates a transmission signal for transmission onto a bus and/or receives a signal from the bus. The communication control device generates the transmission signal according to a frame in which bits having a predetermined temporal length are provided. The communication control device generates the transmission signal so that its bits may be transmitted bus as a dominant state or a recessive state, so that the recessive state is overwritable by the dominant state. The communication control device shortens in the transmission signal at least one bit, which is to be transmitted as the dominant state, by a predetermined value in comparison to a bit that is to be transmitted onto the bus as the recessive state.
