Abstract
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.

17. The WTRU of claim 16 wherein the in- synch and out-of-synch indications are received from a layer 1 (Ll) entity
18. The WTRU of claim 16 wherein a radio link failure on the anchor carrier is declared on a condition that the first timer expired before a predefined number of in- synch indications is counted by the third counter, uplink transmission and enhanced dedicated channel (E-DCH) transmission operations are stopped on all carriers, and a cell update procedure is initiated
19. The WTRU of claim 18 wherein the WTRU stops downlink reception and high speed downlink shared channel (HS-DSCH) operations on all carriers.
20. The WTRU of claim 16 wherein a radio link failure is declared on the supplementary carrier on a condition that the second timer expires before a predefined number of in-synch indications is counted by the fourth counter, and', '-35-1189059-1 uplink transmission and enhanced dedicated channel (E-DCH) transmission operations are stopped on the supplementary carrier.', '-Sδ-', 'I I 89059-1']
