1. A participant of a communication system, the participant comprising:
a transceiver,
wherein the transceiver is configured to transmit data using a first radio network and a second radio network in a frequency band,
wherein the transceiver is configured to transmit data in the first radio network according to a first time/frequency hopping pattern in a first frequency range of the frequency band,
wherein the transceiver is configured to transmit data in the second radio network according to a second time/frequency hopping pattern in a second frequency range of the frequency band,
wherein the first time/frequency hopping pattern and the second time/frequency hopping pattern are different,
wherein the first frequency range and the second frequency range overlap at least partially,
wherein the first radio network is an asynchronous radio network in which participants of the communication system are able to transmit data to a base station at any points in time,
wherein the second radio network is a synchronous radio network in which exclusive resources to transmit the data are allocated to the participants,
wherein the transceiver is configured to transmit an asynchronous uplink data transmission to a base station of the communication system using the first radio network and to receive a downlink data transmission from the base station synchronized in time with the transmitted uplink data transmission using the first radio network, the downlink data transmission comprising signaling information,
wherein the transceiver is configured to receive, based on the signaling information, at least one beacon transmitted by the base station using the second radio network to switch to the second radio network,
wherein the signaling information comprise information on a point in time and/or a frequency channel of the at least one beacon.
