Method and apparatus for performing component carrier-specific reconfiguration

Abstract

Techniques for component carrier-specific reconfiguration are disclosed. A wireless transmit / receive unit (WTRU) is capable of transmitting or receiving via multiple component carriers. The WTRU may perform component carrier reconfiguration on a component carrier basis to add, remove or replace a component carrier. Discontinuous reception (DRX) and / or discontinuous transmission (DTX) may be performed on at least one component carrier, wherein DRX and / or DTX patterns on the component carriers may not overlap each other. A random access procedure may be performed at the target cell on one component carrier while other component carriers are inactive. The component carrier-specific reconfiguration or handover of a component carrier or a channel may be implemented in coordinated multiple point transmission (CoMP), wherein a handover of a control channel, not a traffic channel, may be performed. Alternatively, a handover of a traffic channel may be performed.

Description

[0001] This application is a divisional application of a Chinese patent application with a filing date of March 12, 2010, an application number of 201080011248.8, and a title of "Method and Device for Performing Component Carrier-Specific Reconfiguration". [0002] Cross References to Related Applications [0003] This application claims the benefit of US Provisional Application 61 / 159,606, filed March 12, 2009, which is hereby incorporated by reference as if fully set forth. technical field [0004] This application relates to wireless communications. Background technique [0005] To support higher data rates and spectral efficiency, new wireless technologies have been proposed. For example, the 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) system has been introduced in 3GPP Release 8 (R8). [0006] LTE downlink (DL) transmission is based on Orthogonal Frequency Division Multiple Access (OFDMA) air interface, and LTE uplink (UL) transmission is based...

Problems solved by technology

[0023] In the above conventional LTE R8 handover procedure, due to the implicit use of single carrier in Rel 8, the measurements (measuremnt) currently defined to support LTE Rel-8 handover are not sufficient to support component carrier aggregation in LTE-A switch

In addition, the handover of the entire carrier aggregation is also problematic
