Abstract

La présente invention porte sur un procédé permettant de transmettre des informations de liaison montante, ainsi que sur un dispositif de communication, permettant à des UCI d'être multiplexées sur un PUSCH pour une transmission, ce qui permet d'augmenter la fiabilité de transmission et d'augmenter l'efficacité du système. De façon précise, lorsqu'une ressource de domaine temporel d'un PUCCH transportant des UCI et une ressource de domaine temporel de multiples canaux PUSCH transportant un même bloc de transmission se chevauchent dans un domaine temporel, un dispositif de terminal comporte les UCI transportées sur un premier PUSCH pour une transmission, le premier PUSCH étant un PUSCH parmi les multiples PUSCH remplissant un critère de ligne du temps afin de multiplexer les UCI sur le PUSCH pour une transmission.
