Abstract

La présente invention concerne un procédé et un appareil d'accès multiple pour des canaux physiques. Selon ce procédé, dans le cas d'un système comportant plusieurs canaux physiques de types différents, on commence par configurer pour chaque canal physique des canaux physiques multiples, les modes d'accès pour la transmission, d'une part de l'information de la liaison ascendante, et d'autre part de l'information de liaison descendante. Ensuite, chaque canal physique transmet l'information de liaison ascendante et/ou l'information de liaison descendante en fonction du mode d'accès multiple qui a été configuré pour lui. L'invention permet ainsi de résoudre le problème de l'absence, dans l'état de la technique, de modes d'accès multiples applicables à des canaux physiques différents.
