    • The base stations (RFP1... RFP3) in a radio multi-cellular telecommunication system such as a cellular DECT/GAP system receive a time signal radio message (DCF77) emitted by a time signal emitter, e.g. the DCF77 signal, with which the base station-specific functions of the base stations (RFP1... RFP3), which are based on a telecommunication standard (e.g. the DECT/GAP standard) for wireless telecommunication in a multi-cellular telecommunication system, can be synchronised. A carrier signal (TS) contained in the time-signal radio message (DCF77) and of very precise frequency is used (for example) to adjust the DECT/GAP bit timing (BT). In addition, a time data signal (ZZI) contained in the time signal broadcast message and modulated onto the carrier signal is used (for example) to adjust the DECT/GAP time-slot timing (ZST) and/or time frame timing (ZRT).

    • In order to reduce the power consumed by mobile radio transmitting/receiving devices (PT1, PT2) and thus increase their maximum possible duration of operation, the device-specific transmitting power is automatically regulated depending on special information (FSW, A-CRC, X-CRC), such as field intensity values (FSW) and transmission error values (A-CRC, X-CRC), received and acquired by the mobile radio transmitting/receiving device. The mobile radio transmitting/receiving device (PT1, PT2) has for that purpose a sequential control circuit (RK), in which the value of the controlled variables (here the device-specific transmitting power) follows the changing value of the command variable (here the received and acquired special information).
