Claim:
1. A method of transmitting a source data block to a receiver in a wireless communication system using hybrid automatic retransmission request protocol, comprising: dividing the source data block into a plurality of data segments; performing linear coding on each of the plurality of data segments to generate a plurality of data packets, each of the plurality of data packets including the data segment used for encoding and a corresponding redundancy information segment for decoding in the receiver; transmitting the plurality of data packets to a transmission channel; receiving a feedback message from the receiver, the feedback message indicating which part of the source data block is not decoded correctly; dividing the indicated part of the source data block into the plurality of data segments; padding known data into each of the plurality of data segments to expand the data segment to be a predefined length; performing linear coding on each of the plurality of data segments to generate the plurality of data packets, each of the plurality of data packets including only the redundancy information segment for decoding the data segment in the receiver; and transmitting the plurality of data packets to the transmission channel.
