The invention relates to a method for transmitting data in a transmission interval (201) using a plurality of time slots (202) and a plurality of transmission channels (203) to a receiver (104A) of a radio network (100) comprising a transmitter (103) and at least one additional receiver (104B). The method according to the invention comprises the following steps: transmitting at least one data packet (204) having an embedded identification key (105) by the transmitter (103) via at least one transmission channel (203) in a time slot (202A) of the transmission interval (201), monitoring the at least one transmission channel (203) by means of the receiver (104A) for data packets (204) transmitted in the time slot (202A), said data packets having embedded identifiers (105) that are assigned to the receiver (104A), and switching the receiver (104A) to an idle state until the end of the transmission interval (201) if the receiver (104A) has received no data packet (204) with the embedded identifier (105A) assigned to the receiver (104A) during the time slot (202). The invention also relates to a radio network (100) and to a receiver (104) that are suitable for carrying out the method.
