1. A bus station for exchanging with other bus stations a communication including a data packet and transmission information, comprising:
- an arrangement for storing position information of the bus station in relation to a sequence of bus stations;
an arrangement for determining, from the transmission information, position information of the one of the bus stations that is transmitting;
an arrangement for, on receiving the communication, determining a time slot belonging to the bus station on the basis of the position information of the one of the bus stations that is transmitting and the position information of the bus station;
an arrangement for sending the communication including the data packet after the data packet is received, the communication being sent in a next time slot belonging to the bus station;
an arrangement, in transmitting the communication, for using the direction vector of the received communication;
an arrangement, after the communication has been sent, depending on the direction vector, for checking on whether another bus station has repeated the data packet sent in the communication; and
an arrangement for sending the communication again if no other bus station has repeated the sent data packet;
wherein the communication includes a direction vector indicating that a sequence will be run through in one of a first direction and a second direction that is opposite to the first direction.

Abstract
A bus station or a communication system is described, where the bus stations receive communications containing transmission information from which the position of the transmitting bus station in a sequence of bus stations can. A time slot for the bus station in which the bus station repeats the received communication is calculated from the transmission information and position information stored in the bus station indicating the position of the bus station in the sequence. These bus stations are especially suitable for data exchange by radio.
