METHOD AND APPARATUS FOR MONITORING AND PROCESSING COMPONENT CARRIERS

摘要

PROBLEM TO BE SOLVED: To solve the problem that receiving and transmitting on multiple carriers significantly increases power consumption of a wireless transmit/receive unit (WTRU) and activating and deactivating additional component carriers on demand and quickly is critical to saving WTRU resources and proving savings of power consumption.SOLUTION: A method and apparatus are described which perform bandwidth aggregation by simultaneously monitoring and processing a number of simultaneous and non-contiguous or contiguous component carriers in the downlink. The 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.SELECTED DRAWING: Figure 4
