Abstract
Description
一方、3GPPでは、上りリンクにおけるデータ信号の伝送の高効率化を図るために、「上り高効率伝送方式(EUL:Enhanced Up Link)」の検討が進められている。
図5に、本発明の第1の実施形態に係る移動通信システムにおける下りリンクのチャネルに対する送信アンテナダイバーシチの適用方法について示す。本実施形態に係る移動通信システムでは、基地局Node−Bと移動局UEとの間の上りリンクにおいて、EULが適用されている。
図7及び図8を参照して、本発明の第2の実施形態に係る移動通信システムについて説明する。
図9及び図10を参照して、本発明の第3の実施形態に係る移動通信システムについて説明する。
以下、図11乃至図13を参照して、本発明の第1乃至第3の実施形態に係る移動通信システムで用いられる送信アンテナダイバーシチについて、具体的に説明する。
