METHOD AND APPARATUS FOR SUPPORTING AGGREGATION OF MULTIPLE COMPONENT CARRIERS
First Claim
1. A method for supporting aggregation of multiple component carriers, the method comprising:
- a wireless transmit/receive unit (WTRU), performing a cell search to detect a downlink anchor carrier, the downlink anchor carrier being a component carrier assigned for synchronization and idle mode operations for the WTRU;
the WTRU, in an idle state, camping on the downlink anchor carrier; and
the WTRU via the downlink anchor carrier, and while in the idle state, receiving a broadcast channel for a broadcast message, a paging channel for a paging message, and a control channel for control information.

Abstract
A method and apparatus for supporting aggregation of multiple component carriers are disclosed. A wireless transmit/receive unit (WTRU) in an idle state performs a cell search to detect a downlink anchor carrier and camps on the downlink anchor carrier. The downlink anchor carrier is a component carrier and may be assigned for synchronization and idle mode operations for the WTRU. The WTRU via the downlink anchor carrier receives a broadcast channel for a broadcast message, a paging channel for a paging message, and a control channel for control information necessary while in the idle state. The WTRU receives data via an aggregated carrier having at least two component carriers including a data carrier. The data carrier being a component carrier assigned for data transfer to the WTRU in a connected state.
