(EN) RADIO BASE STATION AND RADIO PARAMETER ADJUSTING METHOD
(FR) STATION RADIO DE BASE ET PROCÉDÉ DE RÉGLAGE D'UN PARAMÈTRE RADIO
(JA) 無線基地局及び無線パラメータの調整方法
Abstract
(EN)
A radio base station adjusts the value of a radio parameter of the local radio base station, thereby controlling an antenna thereof, and further notifies another radio base station of the adjustment of the value of the radio parameter. The local radio base station then receives, from the other radio base station, information about the influence of the adjustment of the radio parameter of the local radio base station on the radio characteristic of the cell formed by the other radio base station. The local radio base station then readjusts, based on the information about the influence on the radio characteristic of the cell formed by the other radio base station, the value of the radio parameter of the local radio base station.
(FR)
Une station radio de base règle la valeur d'un paramètre radio d'une station radio de base locale de manière à en piloter l'antenne, et informe une autre station radio de base du réglage de la valeur du paramètre radio. La station radio de base locale reçoit ensuite de l'autre station radio de base des informations relatives à l'effet du réglage du paramètre radio de la station radio de base locale sur la caractéristique radio de la cellule formée par l'autre station radio de base. La station radio de base locale procède alors à un nouveau réglage de la valeur du paramètre radio de la station radio de base locale compte tenu des informations relatives à l'effet sur la caractéristique radio de la cellule formée par l'autre station radio de base.
(JA)
 無線基地局は、自局の無線パラメータの値を調整することでアンテナを制御し、該無線パラメータの値を調整したことを他の無線基地局に対して通知する。また、無線基地局は、自局の無線パラメータの調整が、他の無線基地局が形成するセルについての無線特性に与える影響に関する情報を、該他の無線基地局から受信する。また、無線基地局は、他の無線基地局が形成するセルについての無線特性に与える影響に関する情報に基づいて、自局の無線パラメータの値を再調整する。
