Abstract

Selon des modes de réalisation, la présente invention concerne des procédés, des dispositifs et des supports lisibles par ordinateur pour la communication. Un dispositif terminal reçoit, en provenance d'un dispositif de réseau, une transmission de canal de commande de liaison descendante pour libérer une configuration SPS, la configuration SPS étant activée avec de multiples transmissions de données de liaison descendante dans une période SPS. Si une rétroaction HARQ pour la transmission de canal de commande de liaison descendante doit être multiplexée sur un livre de codes, le dispositif terminal détermine un ensemble d'emplacements dans le livre de codes pour la rétroaction HARQ ; et transmet, au dispositif de réseau, le livre de codes comprenant la rétroaction HARQ dans l'ensemble d'emplacements sur un canal de liaison montante. De cette manière, la transmission de rétroaction HARQ pour la libération de SPS PDSCH est obtenue.
