Abstract
(EN)
Baseband processings are cooperatively performed among cells performing CAs. The present invention provides a radio base station (eNB) in which: layer-1 function units are configured to independently control respective cells (#0 to #M) in charge of the radio base station (eNB); and layer-2 function units and scheduler function units each are configured to control, at once, a plurality of cells (for example, cells #0 to #2) in each of a plurality of groups (#1 to #N) performing CAs.
(FR)
Des traitements en bande de base sont effectués d'une manière coopérative parmi des cellules effectuant des CA. La présente invention porte sur une station de base radio (eNB) dans laquelle : des unités à fonction de couche 1 sont configurées pour commander indépendamment des cellules respectives (n°0 à n°M) dont est responsable la station de base radio (eNB) ; et des unités à fonction de couche 2 et des unités à fonction de planification qui sont configurées pour commander, instantanément, une pluralité de cellules (par exemple, des cellules n°0 à n°2) dans chaque groupe parmi une pluralité de groupes (n°1 à n°N) effectuant des CA.
(JA)
CAを行うセル間でベースバンド処理を連携して行う。本発明に係る無線基地局eNBでは、レイヤ1機能部は、無線基地局eNB配下の各セル#0~#Mを独立に制御することができるように設けられており、レイヤ2機能部及びスケジューラ機能部は、CAを行うグループ#1~#N内の複数のセル(例えば、セル#0~#2)を一括して制御することができるように設けられている。
