DISCONTINUOUS RECEPTION METHOD AND APPARATUS IN MULTI-COMPONENT CARRIER SYSTEM

摘要

An apparatus and a method for performing a Discontinuous Reception (DRX) in a multi-Component Carrier (CC) system are disclosed. The method includes determining whether a condition for an application of a DRX to a first CC is satisfied and, if the condition is satisfied, performing the DRX on the first CC based on DRX configuration information common to the first CC and a reference CC. The on-duration of the DRX applied to the first CC is synchronized with the on-duration of a DRX mode of the reference CC. Although CCs enter the DRX mode at different points of time, the active or inactive times of the DRX modes are synchronized with each other such that the PDCCHs of all the CCs may be detected at the active times of the respective CCs.
