本発明の実施の形態1では、図2に示すように、BSのアンテナ数を2とし、このBSのセル内に収容されるUE数を3とする。また、3つのUEのうち、1つはアンテナ数1の非MIMO UEとし、残りの2つはアンテナ数2のMIMO UEとする。また、BSは送信ビームを形成し、このビームの情報(ビーム情報)はBSとUEとにおいて共有されるものとする。
実施の形態1では、非MIMO UEがMIMO UEに対して優先的にビームを割り当てられる場合について説明したが、本発明の実施の形態2では、複数のMIMO UEのうちチャネル相関の高いMIMO UEに優先的にビームを割り当てる場合について説明する。
実施の形態2では、複数のMIMO UEのうちチャネル相関の高いMIMO UEに優先的にビームを割り当てる場合について説明したが、本発明の実施の形態3では、複数のMIMO UEのうち信号分離処理能力の低いMIMO UEに優先的にビームを割り当てる場合について説明する。

より受信SINRが劣化するので、Multi-User MIMOシステムに収容できないという問題がある。
本発明の実施の形態1では、図2に示すように、BSのアンテナ数を2とし、このBSのセル内に収容されるUE数を3とする。また、3つのUEのうち、1つはアンテナ数1の非MIMO UEとし、残りの2つはアンテナ数2のMIMO UEとする。また、BSは送信ビームを形成し、このビームの情報(ビーム情報)はBSとUEとにおいて共有されるものとする。
信ビーム形成部105に出力される。
UEか非MIMO UEかを示す端末情報をBSに通知しているため、BSではセル内に非MIMO UEが存在するか否かを確認することができる。非MIMO UEが存在する場合にはST402に移行し、非MIMO UEが存在しない場合にはST404に移行する。
いるものとする。ここで、チャネル推定情報をH、雑音電力をNとすると、各ビーム組合せ時(Bcomb=1〜6のそれぞれに対応)のSINRi(i=1〜6)は以下の式(2)〜(7)で表すことができる。
をBSへフィードバックする。
実施の形態1では、非MIMO UEがMIMO UEに対して優先的にビームを割り当てられる場合について説明したが、本発明の実施の形態2では、複数のMIMO UEのうちチャネル相関の高いMIMO UEに優先的にビームを割り当てる場合について説明する。
ームを形成し、それぞれのUEに対して下りデータを送信する。
実施の形態2では、複数のMIMO UEのうちチャネル相関の高いMIMO UEに優先的にビームを割り当てる場合について説明したが、本発明の実施の形態3では、複数のMIMO UEのうち信号分離処理能力の低いMIMO UEに優先的にビームを割り当てる場合について説明する。
られないので、Bc=0として各UEが自身の端末性能を判断しないようにする。
