The invention concerns a method using a first frequency (fTD) for signals transmitted from the base station to mobile terminals and a second frequency (fTU) for signals transmitted from a mobile terminal to the base station. The first frequency further carries a downlink traffic channel (DT) to a mobile terminal in transmission phase on the uplink traffic channel, and a downlink signalling channel (DL) to mobile terminals in reception phase on the downlink traffic channel. The second frequency further carries an uplink signalling channel (UL) from the mobile terminals in reception phase on the downlink channel, and an uplink signalling channel (UT) from a mobile terminal in transmission phase on the uplink traffic channel.
Le procédé utilise une première fréquence (f TD) pour des signaux transmis de la station de base vers des terminaux mobiles et une seconde fréquence (f TU) pour des signaux transmis d'un terminal mobile vers la station de base. La première fréquence supporte un canal de trafic descendant et la seconde fréquence supporte un canal de trafic montant. La première fréquence supporte encore un canal de signalisation descendante (DT) vers un terminal mobile en phase d'émission sur le canal de trafic montant, et un canal de signalisation descendante (DL) vers des terminaux mobiles en phase de réception sur le canal de trafic descendant. La seconde fréquence supporte encore un canal de signalisation montante (UL) depuis des terminaux mobiles en phase de réception sur le canal de trafic descendant, et un canal de signalisation montant (UT) depuis un terminal mobile en phase d'émission sur le canal de trafic montant.
