Abstract
(EN)
Embodiments of the present application provide a method and apparatus for sending control information. The method comprises: a network device generates first control information for a first TB, wherein the first TB comprises n code blocks (CBs), 1≤n≤N, N is the number of CB groups included at most in the first TB, and N≥1; each CB group comprises at least one CB, the first control information comprises N control information fields, the N control information fields have one-to-one correspondence to the N CB groups included at most in the first TB, a control information field i in the N control information fields is used for indicating whether the CB group corresponding to the control information field i is sent or received, and i ∈[1, N]; and the network device sends the first control information to a terminal device. The embodiments of the present application can make the number of bits included in downlink control information fixed, thereby decreasing the complexity of blind detection of a terminal device, reducing the processing burden of the terminal device, and improving user experience.

La présente invention concerne, dans certains modes de réalisation, un procédé et un appareil d'émission d'informations de commande. Le procédé comporte les étapes suivantes: un dispositif de réseau génère des premières informations de commande pour un premier TB, le premier TB comportant n blocs de code (CB), 1≤n≤N, N étant le nombre de groupes de CB compris au plus dans le premier TB, et N≥1; chaque groupe de CB comportant au moins un CB, les premières informations de commande comportant N champs d'informations de commande, les N champs d'informations de commande présentant une correspondance biunivoque avec les N groupes de CB compris au plus dans le premier TB, un champ d'informations de commande i parmi les N champs d'informations de commande étant utilisé pour indiquer si le groupe de CB correspondant au champ d'informations de commande i est émis ou reçu, et i ∈[1, N]; et le dispositif de réseau envoie les premières informations de commande à un dispositif terminal. Les modes de réalisation de la présente invention peuvent rendre fixe le nombre de bits compris dans des informations de commande de liaison descendante, réduisant ainsi la complexité de la détection en aveugle d'un dispositif terminal, réduisant la charge de traitement du dispositif terminal, et améliorant l'agrément d'utilisation.
