1. A participant of a communication system, comprising:
a transmitter, and
a receiver,
wherein the transmitter is configured to transmit data asynchronously with respect to other participants and/or a base station of the communication system,
wherein the receiver is configured to receive a synchronization data packet of a multicast data transfer of the base station of the communication system, wherein the synchronization data packet is transferred in a frequency range of the frequency band of the communication system that is known to the participant,
wherein the receiver is configured to receive, on the basis of the synchronization data packet, a payload data packet of the multicast data transfer that is referenced in time and/or frequency to the synchronization data packet,
wherein the synchronization data packet of the multicast data transfer is transferred divided onto a plurality of partial synchronization data packets, wherein the plurality of partial synchronization data packets each comprise a part of the synchronization data packet, and wherein the plurality of partial synchronization data packets are transferred distributed in time and/or frequency according to a time and frequency hopping pattern known to the participant,
wherein the receiver is configured to receive the plurality of partial synchronization data packets on the basis of the time and frequency hopping pattern known to the participant,
wherein the plurality of partial synchronization data packets are transferred within the frequency range known to the participant,
wherein the frequency range known to the participant at most corresponds to a reception bandwidth of a receiver of the participant,
wherein the frequency band used by the communication system comprises a bandwidth that is larger than the reception bandwidth of the receiver of the participant at least by the factor 5, or wherein the receiver of the participant comprises a reception bandwidth of 250 kHz or less, or wherein the receiver of the participant comprises a reception bandwidth that corresponds to a bandwidth of two to ten immediately adjacent frequency channels into which the frequency band is subdivided.
