PROBLEM TO BE SOLVED: To solve a problem in which receiving and transmitting on multiple carriers significantly increases power consumption of a WTRU, and to provide a method of activating and deactivating additional component carriers on demand and rapidly, which is critical to saving WTRU resources and providing savings of power consumption.SOLUTION: A method and an 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 WTRU can be configured by an 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. |
