1. A subscriber station for a serial bus system, comprising:
a communication control device configured to control a communication of the subscriber station with at least one other subscriber station of the bus system and to generate a transmit signal, so that, for a message exchanged between subscriber stations of the bus system, a bit time of a signal transmitted to the bus in a first communication phase can differ from a bit time of a signal transmitted in the second communication phase;
wherein the communication control device is configured to generate the transmit signal for the message according to a frame and to insert a field with an edge into the frame after the second communication phase, the field having, before the edge, a predetermined length corresponding to a predetermined time period that is longer than a time duration of the bit time of the first communication phase; and
wherein the edge is provided for synchronization to the communication on the bus for a communication control device of the at least one other subscriber station of the bus system, whose transceiver device is switched, before the predetermined time period, to an operating mode for transmitting and receiving the frame in the first communication phase.
