Abstract
(EN)
The present invention provides a method for coordinated multi-point processing, so as to implement multi-point coordination. The method comprises: when a multi-point coordinated transmission/reception (CoMP) set is transparent to a user equipment, a base station determining a measurement set of the user equipment, and sending the measurement set to the user equipment; the user equipment receiving information about the measurement set, performing channel measurement on cells in the measurement set, and feeding channel state information back to the base station; the base station deciding whether coordinated multi-point transmission is performed on the user equipment according to the channel state information fed back by the user equipment.
(FR)
La présente invention porte sur un procédé de traitement multipoint coordonné, destiné à mettre en œuvre une coordination multipoint. Le procédé comprend les opérations suivantes : lorsqu'un ensemble d'émission/réception coordonnée multipoint (CoMP) est transparent à un équipement utilisateur, une station de base détermine un ensemble de mesures de l'équipement utilisateur, et envoie l'ensemble de mesures à l'équipement utilisateur ; l'équipement utilisateur reçoit des informations concernant l'ensemble de mesures, et effectue une mesure de canal sur des cellules figurant dans l'ensemble de mesures, et renvoie des informations d'état de canal à la station de base ; la station de base décide si une émission multipoint coordonnée est ou non effectuée sur l'équipement utilisateur, conformément aux informations d'état de canal renvoyées par l'équipement utilisateur.
