Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 14:
15. A method for communicating in a serial bus system, the method being carried out using a user station of the bus system that includes a communication control device and a transceiver device, the method comprising the following steps:
controlling, via the communication control device, a communication of the user station with at least one other user station of the bus system; and
transmitting, via the transceiver device, a transmission signal, generated by the communication control device, onto a bus of the bus system, so that for a message that is exchanged between user stations of the bus system, a bit time of a signal that is transmitted onto the bus in a first communication phase is different from a bit time of a signal that is transmitted in the second communication phase, the communication control device generating the transmission signal according to a frame in which a field for a header check sum and a field for a frame check sum are provided, and the communication control device computing the header check sum from all bits in a header of the frame that is formed for the message, with the exception of fixed stuff bits that have been inserted into the header of the frame according to a fixed bit stuffing rule, according to which a fixed stuff bit is to be inserted after a fixed number of bits.
