Abstract
【解決手段】スケジューリングリソースの一単位であるLVRB(PRB)とDVRBを定義し、それぞれを用いたリソース割当方法及びリソース割当情報送信方法を開示する。LVRBの場合、LVRBセットを用いた部分ビットマップスケジューリング方式を提案し、これによるリソース割当情報構成方法を提案する。また、DVRBの場合、1サブフレーム内のPRBを用いてDVRBを定義する方法を提案し、定義された方法で構成されるDVRBを用いてスケジューリングを行った場合、これによるリソース割当情報構成方法を提案する。また、各セルにおいてDVRBが完全に一致して干渉及び衝突が起きるのを防止するために、セル別に異なるDVRBを用いる方法を提案する。
