Abstract

L'invention concerne un procédé, un système et un dispositif pour mettre en œuvre des communications de terminaux. Lors de la réception d'un signal de liaison descendante, un module de communication périphérique peut également recevoir un signal radio, traiter le signal radio afin d'obtenir un signal de bande de base numérique, et envoyer le signal de bande de base numérique à un terminal. Le terminal combine le signal de bande de base numérique obtenu en traitant un signal radio reçu et le signal de bande de base numérique envoyé par le module de communication périphérique, améliorant ainsi la qualité des signaux reçus. Lors de l'envoi d'un signal de liaison montante, le terminal peut diviser un signal à envoyer, et envoie respectivement les signaux divisés via un module de communication de celui-ci et un module de communication périphérique, améliorant ainsi la qualité des signaux envoyés. On améliore ainsi les capacités de communications supportées par le terminal.
