摘要 |
A method for carrying out a survey of a plurality of participant communication devices, and corresponding communication devices. In order to carry out a survey of a plurality of participant communication devices, each of these communication devices is successively assigned an exclusive transmission right to transmit at least one useful message during an authorization period, on the basis of a specific request signal, while the other participant communication devices are only assigned a reception right to receive at least one useful message. The communication device authorized to transmit determines a time window for each participant communication device to respond to the survey, within which the respective participant communication device can transmit its response signal in that it sends at least once its own specific request signal as response signal in order to request the exclusive transmission right.
