Method and apparatus for monitoring and processing component carriers

摘要

A method and apparatus are described which perform bandwidth aggregation by simultaneously monitoring and processing a number of simultaneous, non-contiguous or contiguous component carriers in the downlink. A wireless transmit/receive unit (WTRU) can be configured by an evolved Node-B (eNodeB) to support additional component carriers. A pre-configured additional component carrier may be used. Various methods for activating and deactivating the additional component carrier are also described.

1. A method implemented by a wireless transmit/receive unit (WTRU), the method comprising:
the WTRU transmitting an indication of a bandwidth aggregation capability of the WTRU; the WTRU receiving a radio resource control (RRC) connection reconfiguration message, wherein the RRC connection reconfiguration message configures the WTRU to support at least one additional component carrier, the RRC connection reconfiguration message assigns an identifier for the at least one additional component carrier, and the RRC connection reconfiguration message does not activate the at least one additional component carrier for use by the WTRU; the WTRU receiving a medium access control (MAC) control element (CE), wherein the MAC CE comprises a bit combination field; the WTRU determining that the at least one additional component carrier is to be activated based on the identifier for the at least one additional component carrier assigned in the RRC connection reconfiguration message and the bit combination field of the MAC CE; and the WTRU activating the at least one additional component carrier based on receiving the MAC CE.
