Method for transmitting a message content by means of a plurality of broadcast messages, the transmission of the message content being between a plurality of communication participants in a group of communication participants (20, 21, 22, 23, 24), a plurality of broadcast messages being sent and received between the communication participants in the group of communication participants (20, 21, 22, 23, 24), the plurality of these broadcast messages being part of a message session of broadcast messages, wherein each broadcast message in the message session comprises sequence information, and each communication participant, to send a broadcast message, sets its sequence information, containing a sequence number, in such a way that its sequence number is increased by comparison with the highest sequence number received by the communication participant, wherein a transmitter sends at least one broadcast message, the message content being sent from the transmitter to a plurality of receivers (21, 22, 23, 24) in the group of communication participants (20, 21, 22, 23, 24) by means of the at least one broadcast message by means of a PC5 sidelink functionality, in particular using mode 4 functionality, wherein, to transmit the message content if a specific receiver in the plurality of receivers (21, 22, 23, 24) fails to receive the message content by means of the at least one broadcast message, the method comprises the following steps: - in a first step, the specific receiver detects the failure to receive the message content by means of the at least one broadcast message, the failure to receive the message content being detected on the basis of sequence information of a broadcast message received by the specific receiver and following after the at least one broadcast message, such detection taking place through comparison with sequence information of a broadcast message likewise received by the specific receiver and preceding the at least one broadcast message, - in a second step following after the first step, the specific receiver sends, by means of a further broadcast message, a send request for repeat transmission of the message content, - in a third step following after the second step, one of the plurality of communication participants in the group of communication participants (20, 21, 22, 23, 24) sends the message content to the specific receiver. wherein each broadcast message in the message session comprises sequence information, and each communication participant, to send a broadcast message, sets its sequence information, containing a sequence number, in such a way that its sequence number is increased by comparison with the highest sequence number received by the communication participant, wherein a transmitter sends at least one broadcast message, the message content being sent from the transmitter to a plurality of receivers (21, 22, 23, 24) in the group of communication participants (20, 21, 22, 23, 24) by means of the at least one broadcast message by means of a PC5 sidelink functionality, in particular using mode 4 functionality, wherein, to transmit the message content if a specific receiver in the plurality of receivers (21, 22, 23, 24) fails to receive the message content by means of the at least one broadcast message, the method comprises the following steps: - in a first step, the specific receiver detects the failure to receive the message content by means of the at least one broadcast message, the failure to receive the message content being detected on the basis of sequence information of a broadcast message received by the specific receiver and following after the at least one broadcast message, such detection taking place through comparison with sequence information of a broadcast message likewise received by the specific receiver and preceding the at least one broadcast message, - in a second step following after the first step, the specific receiver sends, by means of a further broadcast message, a send request for repeat transmission of the message content, - in a third step following after the second step, one of the plurality of communication participants in the group of communication participants (20, 21, 22, 23, 24) sends the message content to the specific receiver. - in a first step, the specific receiver detects the failure to receive the message content by means of the at least one broadcast message, the failure to receive the message content being detected on the basis of sequence information of a broadcast message received by the specific receiver and following after the at least one broadcast message, such detection taking place through comparison with sequence information of a broadcast message likewise received by the specific receiver and preceding the at least one broadcast message, - in a second step following after the first step, the specific receiver sends, by means of a further broadcast message, a send request for repeat transmission of the message content, - in a third step following after the second step, one of the plurality of communication participants in the group of communication participants (20, 21, 22, 23, 24) sends the message content to the specific receiver.
