A transmission device and method for repeatedly transmitting punctured data messages is disclosed. The transmission device is configured to puncture an encoded data message over a plurality of consecutive time slots to provide punctured data messages. The punctured data messages include a first punctured data message and a second punctured data message that are alternately transmitted during the consecutive time slots, the first punctured data message arising from puncturing the encoded data message with a first puncture indices series and the second punctured data message arising from the puncturing of the encoded data message with a second puncture indices series that is complementary to the first puncture indices series. A reception device and method for reassembling the encoded data message based on the punctured data messages is also disclosed.
