Patent ID: 8693381

Claim:
A method for discontinuous reception (DRX), comprising: configuring DRXs for a plurality of component carriers, and using one or more component carriers as an anchor component carrier; the anchor component carrier determining DRXs of other non-anchor component carriers; wherein, the operation of the anchor component carrier determining DRX of the non-anchor component carriers comprises: the anchor component carrier determining DRX of the non-anchor component carriers through a control signaling or a preset condition; wherein, the non-anchor component carriers determine DRX configuration or DRX act of the current non-anchor component carrier according to the DRX configuration or DRX act of the anchor component carrier; wherein, the anchor component carrier achieves control on DRX of the non-anchor component carriers by sending a control signaling from an enhanced Node B (eNB) to the non-anchor component carriers; wherein, the control signaling specifically comprises: a MAC CE or a PDCCH signaling or a RRC signaling; in a state migration scene of intermigration between short DRX cycle and long DRX cycle, the method further comprises: the eNB triggering the state migration in the MAC CE transmitted by the anchor component carrier, which specifically comprises: the anchor component carrier notifying, through the MAC CE transmitted by the eNB, the current non-anchor component carrier to migrate from short DRX cycle to long DRX cycle; or the anchor component carrier notifying, through the MAC CE transmitted by the eNB, the current non-anchor component carrier to migrate from long DRX cycle to short DRX cycle; or the non-anchor component carrier migrating from long DRX cycle to short DRX cycle by starting the DRX inactivity timer when receiving or transmitting data of the present component carrier according to received downlink assignment or uplink grant instructed by the PDCCH of the anchor component carrier, and entering the short DRX cycle when the DRX inactivity timer times out; or the method further comprises: the eNB triggering the state migration in the MAC CE transmitted by the non-anchor component carrier, which specifically comprises: the eNB transmitting the MAC CE in the current non-anchor component carrier to notify the current non-anchor component carrier to migrate from short DRX cycle to long DRX cycle; or, the eNB transmitting the MAC CE in the current non-anchor component carrier, and notifying the current non-anchor component carrier to migrate from long DRX cycle to short DRX cycle.
