Abstract
Description
復が1つのREGにマッピングされる。
はPHICHグループのi番目の反復が伝送されるOFDMシンボルのインデックスであり、k´iは周波数ドメインのインデックスである。
ICHが互いに異なるREGを持っている様々なOFDMシンボルを通して伝送される場合、各OFDMシンボルにおけるREGの個数が異なるため、各PHICHの反復が周波数帯域全体に均等に分布できなくなる。セルIDによって1番目のREGの位置を指定し、1番目のREGのインデックスを基準に一定間隔で反復パターンを割り当てなければならない。ところが、各OFDMシンボルにおけるREGの個数によって、インデックスに応じた周波数位置の解像度が異なるため、基準位置が変わるという問題がある。
