Abstract

La présente invention concerne un procédé de traitement de données et un appareil de communication, capables d'améliorer l'efficacité de traitement de données d'un dispositif terminal et d'améliorer la robustesse de la transmission de données. Le procédé peut comprendre les étapes suivantes : un dispositif terminal reçoit des premières données sur une première ressource temps-fréquence et reçoit des secondes données sur une seconde ressource temps-fréquence, les ressources de domaine fréquentiel des première et seconde ressources temps-fréquence ne se chevauchant pas, ou les ressources de domaine temporel des première et seconde ressources temps-fréquence ne se chevauchant pas ; le dispositif terminal reçoit des informations d'indication, les informations d'indication pouvant indiquer une politique de transmission des premières données et des secondes données par le dispositif terminal, ou les informations d'indication peuvent indiquer si les premières données et les secondes données peuvent être soumises à une combinaison et à un décodage d'informations de bits souples ; et le dispositif terminal détermine, selon les informations d'indication, que les premières données et les secondes données peuvent être soumises à une combinaison et à un décodage d'informations de bits souples, ou le dispositif terminal détermine, selon les informations d'indication, que les premières données et les secondes données ne peuvent pas être soumises à une combinaison et à un décodage d'informations de bits souples.
