Description

A method for allocating physical resources to an Acknowledgement (ACK)/Negative Acknowledgement (NACK) signal channel representative of a response signal in a wireless communication system. The method includes grouping ACK/NACK signal channels corresponding to a plurality of resource blocks used for transmission of a data channel or a control channel into a plurality of groups so ACK/NACK signal channels having consecutive indexes do not belong to the same group; and allocating same frequency resources to ACK/NACK signal channels belonging to the same ACK/NACK signal channel group and allocating orthogonal sequences so ACK/NACK signal channels in each ACK/NACK signal channel group are distinguished in a code domain.

Procédé d'attribution de ressources physiques à un canal de signal ACK/NACK (Accusé de réception/accusé de réception négatif) correspondant à un signal de réponse dans un système de communication sans fil. Ce procédé consiste: à grouper des canaux de signal ACK/NACK correspondant à une pluralité de blocs de ressources utilisés pour la transmission d'un canal de données ou d'un canal de commande en une pluralité de canaux de signal ACK/NACK ayant des indexes consécutifs, n'appartenant pas au même groupe; et à attribuer les mêmes ressources de fréquence aux canaux de signal ACK/NACK d'un même groupe de canaux de signal ACK/NACK et à attribuer des séquences orthogonales de sorte que les canaux de signal ACK/NACK dans chaque groupe canaux de signal puissent être distingués dans un domaine de code.
