Title
(EN) BASE STATION DEVICE AND RADIO COMMUNICATION METHOD
(FR) DISPOSITIF DE STATION DE BASE, ET PROCÉDÉ DE RADIOCOMMUNICATIONS
Abstract
(EN) Communication to a terminal inferior in reception condition is positively accommodated in a communication device having a variable directivity, in view of good reception characteristics of a communication device having a variable directivity, thereby reducing power consumed by this terminal to reduce interference and increasing a subscriber capacity in the system.
(FR) La présente invention permet la prise en compte satisfaisante, par un appareil de communications multidirectionnel, des communications à destination d'un terminal subissant de mauvaises conditions de réception. A cet effet, pour conserver à l'appareil de communications multidirectionnel de bonnes caractéristiques de réception, on limite la puissance électrique utilisée par le terminal de façon à réduire les interférences, tout en permettant au système de prendre en compte un plus grand nombre d'abonnés.
