Description
図1に示すように、本発明に係る基地局1は、3D MIMOのアンテナセット10を有する。アンテナセット10においては、2次元すなわち縦横方向または3次元にアンテナ素子が配列されている。したがって、基地局1は、送信信号の位相および振幅を、ビームフォーミング行列(プリコーディング行列)で調整することにより、水平方向(方位角方向)に加えて垂直方向(すなわち俯角および仰角方向)にビームの方向を制御する。アンテナセット10は必ずしも2または3次元である必要は無く、水平または垂直方向に1次元にアレー配置されていても良い。
プリコードされた複数のCRSをUEが区別することができる形式およびCRSの送信方式を示す情報を規格の仕様書に規定すべきである。CRSの送信方式を示す情報は、少なくとも基地局から送信されるCRSの数、各CRSの生成およびマッピンク等に用いるID、各CRSに割り当てられたリソースエレメントと送信アンテナポート数(式または表の形式でよい)を含んでいても良い。なお、当該IDはリリース8で規定されているセルIDでも良いし、バーチャルセルIDであっても良い。
図18は、UEのアイドル状態(RRC_IDLE)での実施の形態に係る処理の流れを示すシーケンス図である。図において下線が引かれた箇所は実施の形態に係る新規な特徴を示し、他の箇所は従来の機能を示す。実施の形態において、複数の基地局の各々は、CRSの送信アンテナポートマッピングを行い、複数のCRSのプリコーディングを行って、プリコードされた複数のCRSのビームを送信する。また、これらの基地局は、MIBおよび従来のSIBに加えて、新規なSIB(SIBXと表記する)で複数のCRSの送信方式を示す情報を送信する。UEは、複数の基地局の各々からの複数のCRSのビームの複数の受信品質(例えばRSRPまたはRSRQ)を測定し、複数の基地局の複数のビームから得られた最良の受信品質または閾値より高い受信品質に基づいてセル選択または再選択を実行する。
