Abstract

L'invention concerne un procédé permettant à un premier dispositif d'établir une communication sans fil, et un dispositif destiné à le prendre en charge. Le procédé peut comprendre les étapes consistant à : acquérir des informations relatives à un code de couverture orthogonal ; et effectuer une répétition de canal partagé de liaison montante sur la base du code de couverture orthogonal. Par exemple, le code de couverture orthogonal peut être appliqué entre les répétitions de canal partagé de liaison montante. Par exemple, sur la base du fait qu'au moins l'une parmi les répétitions de canal partagé de liaison montante et un canal de contrôle de liaison montante se chevauchent, des informations de contrôle de liaison montante relatives au canal de contrôle de liaison montante peuvent être multiplexées sur un canal partagé de liaison montante.
