Abstract (en)
[origin: CA3072116A1] The invention relates to a method for bidirectional data transmission, preferably taking place in a narrowband system, between a base station (101) and a terminal device (102), preferably a plurality of terminal devices (102), wherein the terminal device (102) and the base station (101) each have their own frequency reference unit and the data are transmitted between the base station (101) and the terminal device (102) over different frequencies, having the following method steps: a basic transmit frequency (201) is defined for transmitting data from the terminal device (102) to the base station (101); the terminal device (102) defines a terminal device transmit frequency (202) on the terminal device side for transmitting data from the terminal device (102) to the base station (101), wherein a frequency offset .DELTA.foffset exists between the basic transmit frequency (201) and the terminal device transmit frequency (202); the terminal device (102) opens a receive window to receive data originating from the base station (101), wherein the frequency offset .DELTA.foffset . is taken into account for the opening of the receive window; the base station (101) determines the terminal device transmit frequency (202); the base station (101) transmits data to the terminal device (102) on the basis of the determined terminal device transmit frequency (202).
