Abstract

La présente invention concerne un procédé permettant de renvoyer des informations d'état de canal, qui comprennent les étapes suivantes : un terminal détermine le nombre de bits d'informations d'état de canal périodique devant être renvoyé et la longueur cible une fois que sont codées les informations d'état de canal périodique ; le terminal évalue si le nombre de bits d'informations d'état de canal périodique devant être renvoyé n'est pas supérieur à un seuil prédéfini, code l'information d'état de canal périodique en un mode de codage en bloc linéaire et intercepte les informations codées en fonction de la longueur cible déterminée, après codage des informations d'état de canal périodique ; sinon, le terminal code les informations d'état de canal périodique en un mode de codage à convolution cyclique et intercepte les informations codées en fonction de la longueur cible déterminée après codage des informations d'état de canal périodique ; le terminal module les informations codées interceptées et les transmet sur un port d'antenne. L'invention concerne de même un système permettant de renvoyer les informations d'état de canal. L'invention permet d'éviter la limite en matière de charge des informations d'état de canal, de sorte que la plage d'application est plus large. Le codage en bloc linéaire adopté par l'invention permet d'acquérir le gain de codage maximum afin d'optimiser les performances.
