Abstract
(EN)
Disclosed are a space-division multiplexing method and system. The method comprises: determining space-division group information of a user equipment according to acquired user equipment information; determining a precoding weight of a corresponding port according to a channel response of the user equipment and a CRS port mapping relationship in the same space-division group; determining a corrected precoding weight of the user equipment according to the channel response of the corresponding port of the user equipment in the same space-division group, the cell broadcast right and the precoding weight; and determining the actual transmit power of the user equipment according to the corrected precoding weight, and transmitting, according to the actual transmit power, data transmitted by the user equipment.

La présente invention concerne un procédé et un système de multiplexage spatial. Le procédé consiste à : déterminer des informations de groupe à répartition spatiale d'un équipement utilisateur en fonction d'informations d'équipement utilisateur acquises; déterminer un poids de précodage d'un port correspondant en fonction d'une réponse de canal de l'équipement utilisateur et d'une relation de mappage de port CRS dans le même groupe à répartition spatiale; déterminer un poids de précodage corrigé de l'équipement utilisateur en fonction de la réponse de canal du port correspondant de l'équipement utilisateur dans le même groupe à répartition spatiale, du droit de diffusion cellulaire et du poids de précodage; et déterminer la puissance de transmission réelle de l'équipement utilisateur en fonction du poids de précodage corrigé, et transmettre, en fonction de la puissance de transmission réelle, des données transmises par l'équipement utilisateur.
