CA 2751725

A method and apparatus are described for performing a dual-carrier operation. A first timer is initiated for an anchor carrier and a second timer is initiated for a supplementary carrier. A physical channel failure may be declared on a condition that either of the timers expire before a predefined number of in-synch indication received from a layer 1(L1) entity is counted. Uplink transmission and enhanced dedicated channel (E-DCH) operations may be stopped on a supplementary carrier associated with the physical channel failure, but may be continued on an anchor carrier that has a physical channel established. If the physical channel failure is associated with the anchor carrier, uplink transmission and E-DCH transmission operations are stopped on all carriers.

L'invention porte sur un procédé et un appareil pour réaliser un fonctionnement à double porteuse. Un premier temporisateur est déclenché pour une porteuse d'ancrage et un second temporisateur est déclenché pour une porteuse supplémentaire. Une défaillance du canal physique peut être déclarée à condition que l'un ou l'autre des temporisateurs expire avant qu'un nombre prédéfini d'indications de synchronisation reçues en provenance d'une entité de couche 1 (L1) ne soit compté. Une transmission en liaison montante et des opérations de canal dédié amélioré (E-DCH) peuvent être stoppées sur une porteuse supplémentaire associée à la défaillance du canal physique, mais peuvent être continuées sur une porteuse d'ancrage qui a un canal physique établi. Si la défaillance du canal physique est associée à la porteuse d'ancrage, la transmission en liaison montante et les opérations de transmission E-DCH sont stoppées sur toutes les porteuses.
