Description
エラーのあるPDUは捨てられ、このPDUの新たなコピーが再送されて別途復号される。PDUの前と後のバージョンの連結は行われない。
エラーがあり再送が必要となるPDUは、捨てられることはなく、後の復号のために送信機が供給する増分冗長ビットと連結される。再送されたPDUは時々、より高い符号化レートを有しており、受信機側で記憶値と連結される。これは、それぞれの再送において、ほんのわずかな冗長性しか付加されないことを意味する。
タイプIIとほぼ同様であるが、全ての再送PDUが、自己復号可能(self-decodable)である点のみが異なる。自己復号可能とは、そのPDUが、以前のPDUとの連結形成を要することなく、復号可能であることを意味している。このことは、あるPDUが激しくダメージを受けて、ほとんど全ての情報が再利用不能になったときに、有用である。
