Abstract: front page image
(EN) Disclosed are a coordinated multi-point transmission method and device. The calculation amount is reduced by respectively performing matrix decomposition on a downlink channel matrix corresponding to two coordinated points, and a launch weight matrix corresponding to the coordinated points is obtained according to the decomposed downlink channel matrix of the coordinated points, so that the receiving signals of each of the coordinated points, which arrive at a UE side, are partially coherent in direction, and a coherent combination gain is obtained, thereby still ensuring the coherent combination gain under a relatively low computation complexity.
(FR) La présente invention concerne un procédé et un dispositif de transmission multipoint coordonnée. La quantité de calcul est réduite par réalisation respectivement d'une décomposition matricielle sur une matrice de canal de liaison descendante correspondant à deux points coordonnés, et une matrice de poids d'émission correspondant aux points coordonnés est obtenue en fonction de la matrice de canal de liaison descendante décomposée des points coordonnés, de manière que les signaux de réception de chacun des points coordonnés, qui arrivent côté UE, soient partiellement cohérents en direction, et qu'un gain de combinaison cohérente soit obtenu, ce qui permet d'assurer encore le gain de combinaison cohérente avec une relativement faible complexité de calcul.
(ZH) 本发明实施例公开了一种协作多点传输的方法及设备,通过对两个协作多点对应的下行信道矩阵分别进行矩阵分解,以减少计算量,并根据分解后的所述协作多点的下行信道矩阵得到所述协作多点对应的发射权值矩阵,使得各协作多点到达UE侧的接收信号方向部分相干,并获得了相干合并增益,从而使得在较低的计算复杂度下,依然能够保证相干合并增益。
