Abstract
(EN)
Disclosed are a signal sending method and device. The method comprises: according to the number of enhanced control channel elements (eCCEs) occupied by an enhanced physical downlink control channel (E-PDCCH), acquiring a scrambling code sequence corresponding to the E-PDCCH; scrambling a signal borne by the E-PDCCH by using the corresponding scrambling code sequence; and sending the scrambled signal to a receiving apparatus. By means of the present invention, decoding errors in blind detection can be avoided by scrambling a sequence to facilitate decoding.

L'invention porte sur un procédé et un dispositif d'envoi de signal. Le procédé consiste à : en fonction du nombre d'éléments de canal de commande amélioré (eCCE) occupés par un canal de commande de liaison descendante physique amélioré (E-PDCCH), acquérir une séquence de code d'embrouillage correspondant à l'E-PDCCH ; embrouiller un signal véhiculé par l'E-PDCCH par utilisation de la séquence de code d'embrouillage correspondante ; et envoyer le signal embrouillé à un appareil récepteur. Au moyen de la présente invention, des erreurs de décodage en détection aveugle peuvent être évitées par embrouillage d'une séquence afin de faciliter le décodage.
