Abstract
(EN)
The invention relates to a transmitting device (100) and a receiving device (300) for reliable reception of control messages such as downlink control information. The transmitting device (100) forms a control message (510) which comprises control information, a first CRC word (W1) and a second CRC word (W2). The control message (510) is sent to the receiving device (300) which obtains a first CRC check outcome based on performing a first CRC check on the control message (510), and a second CRC check outcome based on performing a second CRC check on the control message (510). Thereby, more reliable reception of control messages (510) is possible. Furthermore, the invention also relates to corresponding methods and a computer program.

L'invention concerne un dispositif de transmission (100) et un dispositif de réception (300) pour une réception fiable de messages de commande tels que des informations de commande de liaison descendante. Le dispositif de transmission (100) forme un message de commande (510) qui comprend des informations de commande, un premier mot CRC (W1) et un second mot CRC (W2). Le message de commande (510) est envoyé au dispositif de réception (300) qui obtient un premier résultat de vérification CRC sur la base de la réalisation d'une première vérification CRC sur le message de commande (510), et d'un second résultat de contrôle CRC sur la base de la réalisation d'une seconde vérification CRC sur le message de commande (510). Ainsi, une réception plus fiable de messages de commande (510) est possible. En outre, la présente invention concerne également des procédés correspondants et un programme informatique.
