Abstract: front page image
(EN)A first base station (110) transmits precoded wireless signals. Furthermore, the first base station (110) switches a weight of precoding corresponding to a switch pattern selected from among a plurality of switch patterns having different pattern lengths, and notifies other base stations of the selected switch pattern. A second base station (120) transmits, to a terminal (130) connected to the second base station, wireless signals using a time resource allocated on the basis of the switch pattern notified from the first base station (110). The terminal (130) is connected to the second base station (120), and receives the wireless signals transmitted from the second base station (120).
(FR)L'invention concerne la transmission par une première station de base (110) de signaux sans fil précodés. En outre, la première station de base (110) commute un poids de précodage correspondant à un motif de commutation choisi parmi une pluralité de motifs de commutation ayant différentes longueurs de motif et informe les autres stations de base du motif de commutation sélectionné. Une seconde station de base (120) transmet, à un terminal (130) connecté à la seconde station de base, des signaux sans fil utilisant une ressource temporelle attribuée sur la base du motif de commutation indiqué par la première station de base (110). Le terminal (130) est connecté à la seconde station de base (120) et reçoit les signaux sans fil transmis par la seconde station de base (120).
(JA) 第1基地局(110)は、プリコーディングした無線信号を送信する。また、第1基地局(110)は、パターン長が異なる複数の切替パターンの中から選択した切替パターンによってプリコーディングの重みを切り替え、選択した切替パターンを他の基地局へ通知する。第2基地局(120)は、第1基地局(110)から通知された切替パターンに基づいて割り当てた時間リソースを用いて、自局に接続する端末(130)へ無線信号を送信する。端末(130)は、第2基地局(120)に接続し、第2基地局(120)から送信された無線信号を受信する。
