A method and apparatus for code multiplexing one or more control signals onto a shared control channel. According to the present invention, a control signal for transmission from a base station to a mobile station terminal is repeated in each slot of a predetermined time interval. The control signal in each slot is spread using a bit-level spreading sequence, where the bit-level spreading sequence varies from slot to slot according to a predefined sequence-hopping pattern. The spread control signals generated for transmission to each mobile station terminal are then combined and spread using a common channelization code.

L'invention concerne un procédé et un appareil de multiplexage par code d'un ou de plusieurs signaux de commande sur un canal de commande partagé. Selon la présente invention, un signal de commande de transmission d'une station de base vers un terminal de station mobile est répété dans chaque position d'un intervalle temporel prédéterminé. Le signal de commande de chaque position est étalé à l'aide d'une séquence d'étalement de bit variant d'une position à l'autre en fonction d'un modèle de saut de séquence prédéfini. Les signaux de commande d'étalement générés pour être transmis à chaque terminal de station mobile sont alors combinés et étalés à l'aide d'un code de découpage en canaux commun.
