METHOD AND APPARATUS FOR PERFORMING PHYSICAL DEDICATED CHANNEL ESTABLISHMENT AND MONITORING PROCEDURES

摘要

PROBLEM TO BE SOLVED: To provide an improved method for radio link establishment and monitoring.SOLUTION: Provided is a method and apparatus for performing 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 expires before a predefined number of radio link acquisition indications received from a layer 1 (L1) entity is counted. Uplink transmission and enhanced dedicated channel (E-DCH) operation 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 operation are stopped on all carriers.
