The method provided includes generating a channel changing negotiating message including information about at least one frequency channel the ultra-wideband radio communication device intends to change to. The method provided further includes transmitting the channel changing negotiating message to at least one other ultra-wideband radio communication device with which the ultra-wideband radio communication device has an established communication connection in a current frequency channel. According to the method provided, the ultra-wideband radio communication device may receive channel changing negotiating messages from the at least one other ultra-wideband radio communication device, where the channel changing negotiating messages include information about at least one frequency channel the other ultra-wideband radio communication device intends to change to. The ultra-wideband radio communication device may determine whether the ultra-wideband radio communication device is able to change to the at least one frequency channel included in the channel changing negotiating message, and may generate a further channel changing negotiating message including information about at least one frequency channel the ultra-wideband radio communication device intends to change to. The ultra-wideband radio communication device may then transmit the further channel changing negotiating message to the other ultra-wideband radio communication device. After a predetermined interval, the ultra-wideband radio communication device may select, based on a predetermined criterion, the frequency channel to change to, if the ultra-wideband radio communication device is the initiator of the intended change of frequency channel.
