Abstract

L'invention concerne un procédé et un appareil de sélection de ressources de transmission. Le procédé comprend les étapes suivantes : une extrémité de réception reçoit des informations d'indication d'un premier ensemble de ressources ainsi que des informations d'indication d'un second ensemble de ressources, le premier ensemble de ressources étant un ensemble de ressources sans octroi en liaison montante configurées pour l'extrémité de réception par une extrémité de transmission, et le second ensemble de ressources étant un ensemble de ressources, déjà attribuées à un service d'octroi, dans des ressources de liaison montante de référence ; et l'extrémité de réception détermine une politique de transmission en liaison montante en fonction des informations d'indication du premier ensemble de ressources et des informations d'indication du second ensemble de ressources. Selon l'invention, une extrémité de réception peut déterminer les ressources finalement occupées par une transmission de service sans octroi en liaison montante et un mécanisme de transmission en fonction de la condition des ressources sans octroi en liaison montante occupées par des ressources de services autorisées en liaison montante de façon à pouvoir réaliser efficacement le multiplexage entre la transmission de service sans octroi en liaison montante et la transmission de service autorisée en liaison montante.
