CA 2686941

A method for transmitting downlink control information and a method for generating a codeword for the same are disclosed. In generating a long code having a low code rate, a basic code of which minimum distance between codes is maximized is repeated by a prescribed number of times and bits of the repeated code are adjusted. Therefore, a minimum distance condition between codes of a long code is satisfied and simultaneously the code can be simply generated. Furthermore, control information can be transmitted with a low error rate by using the generated code.

L'invention concerne un procédé de transmission d'informations de commande de liaison descendante et un procédé de génération d'un mot codé pour ledit procédé. Lors de la génération d'un code long présentant un taux de codage faible, un code de base dont la distance minimum entre codes est maximisée est répété un nombre prescrit de fois et des bits du code répété sont réglés. Par conséquent, une condition de distance minimum entre codes d'un code long est satisfaite et simultanément le code peut être généré simplement. En outre, des informations de commande peuvent être transmises avec un faible taux d'erreur par utilisation du code généré.
