Abstract
La présente invention concerne, selon certains aspects, la planification coopérative de liaison descendante à entrées et sorties multiples (MIMO). Des caractéristiques sont décrites pour planifier des transmissions au sein d'un réseau MIMO pour attribuer de manière efficiente des ressources compte tenu des besoins et/ou des caractéristiques de dispositifs desservis par le réseau. Le mode de liaison descendante ou l'ensemble actif peuvent être planifiés en se basant au moins en partie sur les informations d'état de canal et des informations supplémentaires de système de réseau détectées par le dispositif de planification ou dont celui-ci dispose autrement.
