The present invention provides for transmitting a spread signal in a mobile communication system. The present invention includes spreading a signal using a plurality of spreading codes, wherein the plurality of spreading codes have a spreading factor, multiplexing the spread signal by code division multiplexing, transmitting the multiplexed signal via a plurality of neighboring frequency resources of one OFDM symbol of a first antenna set, and transmitting the same multiplexed signal via a plurality of neighboring frequency resources of one OFDM symbol of a second antenna set.

La présente invention concerne l'émission d'un signal à étalement de spectre dans un système de communication mobile. L'invention consiste à étaler un signal en utilisant une pluralité de codes d'étalement, laquelle pluralité de codes d'étalement comporte un facteur d'étalement, à multiplexer le signal étalé par multiplexage par division de code, à émettre le signal multiplexé par l'intermédiaire d'une pluralité de ressources de fréquences voisines d'un symbole OFDM d'un premier ensemble d'antennes, et à émettre le même signal multiplexé par l'intermédiaire d'une pluralité de ressources de fréquences voisines d'un symbole OFDM d'un deuxième ensemble d'antennes.
