Title (EN) BASE STATION DEVICE
(FR) DISPOSITIF DE STATION DE BASE
(JA) 基地局装置
Abstract:
(EN) Provided is a base station device with which it is possible to prevent the occurrence of communication delays when performing inter-cell interference control employing an Almost Blank Subframe (ABS). This base station device is capable of implementing inter-cell interference control by means of an ABS pattern setting in which a prescribed number of subframes serves as one cycle. When the ABS pattern is to be switched, a Modulation and Coding Scheme (MCS) index value determined by adaptive modulation control is changed for subframes for which communication with a mobile station device has been permitted prior to the ABS pattern being switched, for communications at or before the switching time and within a certain period thereof.
(FR) L'invention concerne un dispositif de station de base avec lequel il est possible d'empêcher la survenue de retards de communication lors de la réalisation d'une lutte contre les brouillages entre cellules en employant une sous-trame quasi vide (ABS). Ce dispositif de station de base est capable de mettre en œuvre une lutte contre les brouillages entre cellules au moyen d'un paramétrage de motif d'ABS dans lequel un nombre prescrit de sous-trames joue le rôle d'un seul cycle. Lorsque le motif d'ABS doit être changé, une valeur d'index de schéma de modulation et de codage (MCS) déterminée par commande de modulation adaptative est modifiée pour des sous-trames pour lesquelles la communication avec un dispositif de station mobile a été autorisée avant que le motif d'ABS soit changé, pour des communications à ou avant l'instant du changement et dans la limite d'une certaine durée par rapport à celui-ci.
(JA) ABSを用いたセル間干渉制御を行うときの通信遅延の発生を防止できる基地局装置を提供する。基地局装置は、所定数のサブフレームを1周期とするABSパターンの設定によりセル間干渉制御を実行可能であり、ABSパターンの切り替えがあるとき、その切替時刻より以前で且つ一定時間内の通信に対して、そのABSパターンの切り替え前に移動局装置との間の通信が許可されるサブフレームについて、適応変調制御により決定されるMCS(Modulation and Coding Scheme)インデックスの値を変更する。
