Abstract
A transmitting device for supporting Hybrid Automatic Repeat Request (HARQ) includes scrambling and encoding, in which the order of scrambling and encoding is changed compared to the conventional transmitter. Likewise, a receiving device for supporting HARQ includes descrambling and decoding, in which the order of descrambling and decoding is changed compared to the conventional receiver. In particular, the transmitting device is configured to encode at least one data unit using Forward Error Correction (FEC) coding, scramble the encoded data unit based on a scrambling seed, provide an indication of the scrambling seed that is separate from the scrambled and encoded data unit, and transmit the indication of the scrambling seed and then the scrambled and encoded data unit to the receiving device.
