本発明に係る基地局は、移動端末と、ビームを用いて移動端末と無線通信を行う少なくとも1つの基地局と、を備える通信システムにおける基地局であって、移動端末が通信品質を判断するために用いるチャネル状態情報参照信号を送信する。
図2は、3GPPにおいて議論されているLTE方式の通信システム200の全体的な構成を示すブロック図である。図2について説明する。無線アクセスネットワークは、E-UTRAN(Evolved Universal Terrestrial Radio Access Network)201と称される。通信端末装置である移動端末装置(以下「移動端末(User Equipment:UE)」という)202は、基地局装置(以下「基地局(E-UTRAN NodeB:eNB)」という)203と無線通信可能であり、無線通信で信号の送受信を行う。
実施の形態2は、例えば、通信状況の変化に応じて基本ビームを変更することによって通信を維持する技術に関し、さらには移動端末のビームの指定に関する。
実施の形態3は、例えば、他基地局に対する干渉対策に関する。
実施の形態4は、例えば、可逆性対応可否への対応に関する。
