1. A method for using an unlicensed carrier resource, comprising:
- receiving, by an eNode B (eNB), indication information reported by a User Equipment (UE), wherein the indication information is used for indicating that a local Secondary Cell (Scell) of the UE is idle;
detecting, by the eNB upon a trigger of the indication information, whether a local Scell of the eNB is idle or not; and
judging, by the eNB according to a detection result of detecting whether the local Scell of the eNB is idle or not, whether or not to use an unlicensed carrier resource which has been occupied by the UEreceiving, by the UE, control information transmitted by the eNB, wherein the control information is used for controlling whether or not the UE uses the unlicensed carrier resource which has been occupied by the UE;
sending in the local Scell of the UE, by the UE, a Physical Uplink Shared Channel (PUSCH) data block which is controlled by no Uplink (UL) scheduling information of the eNB, wherein demodulation information used for the eNB to demodulate the PUSCH data block is fed back to the eNB through a Physical Uplink Control Channel (PUCCH) of a licensed carrier.

Abstract
Methods and devices for using an unlicensed carrier resource are provided. In a method for using an unlicensed carrier resource, an eNode B (eNB) receives indication information reported by a User Equipment (UE), where the indication information is used for indicating that a local Secondary Cell (Scell) of the UE is idle; upon a trigger of the indication information, the eNB detects whether a local Scell of the eNB is idle or not; and the eNB judges, according to a detection result, whether or not to use an unlicensed carrier resource which has been occupied by the UE.

6. A method for using an unlicensed carrier resource, comprising:
-
when a local Secondary Cell (Scell) of a User Equipment (UE) is idle, sending, by the UE, indication information for Indicating that the local Scell of the UE is idle to an eNode B (eNB); and after the eNB judges, according to the indication information, whether or not to use an unlicensed carrier resource which has been occupied by the UE, receiving, by the UE, control information transmitted by the eNB, wherein the control information is used for controlling whether or not the UE uses the unlicensed carrier resource which has been occupied by the UE;
sending in the local Scell of the UE, by the UE, a Physical Uplink Shared Channel (PUSCH) data block which is controlled by no Uplink (UL) scheduling information of the eNB, wherein demodulation information used for the eNB to demodulate the PUSCH data block is fed back to the eNB through a Physical Uplink Control Channel (PUCCH) of a licensed carrier. - View Dependent Claims (7, 8, 9)

10. A system for using an unlicensed carrier resource, which comprises an eNode B (eNB) and a UE, and the eNB comprising a hardware processor configured to execute program modules comprising:
-
a receiving module, configured to receive indication information reported by a User Equipment (UE), wherein the indication information is used for indicating that a local Secondary Cell (Scell) of the UE is idle; a detection module, configured to, upon a trigger of the indication information, detect whether a local Scell of the eNB is idle or not; and a judgment module, configured to judge, according to a detection result of detecting whether the local Scell of the eNB is idle or not, whether or not to use an unlicensed carrier resource which has been occupied by the UE; the UE is configure to receive control information transmitted by the eNB, wherein the control information is used for controlling whether or not the UE uses the unlicensed carrier resource which has been occupied by the UE, and the UE is further configure to send in the local Scell of the UE a Physical Uplink Shared Channel (PUSCH) data block which is controlled by no Uplink (UL) scheduling information of the eNB, wherein demodulation information used for the eNB to demodulate the PUSCH data block is fed back to the eNB through a Physical Uplink Control Channel of a licensed carrier. - View Dependent Claims (11, 12, 13, 14)

15. A device for using an unlicensed carrier resource, applied to a User Equipment (UE) and comprising a hardware processor configured to execute program modules comprising:
a sending module, configured to, when a local Secondary Cell (Scell) of the UE is idle, send indication information for indicating that the local Scell of the UE is idle to an eNode B (eNB); and a receiving module, configured to, after the eNB judges according to the indication information whether or not to use an unlicensed carrier resource which has been occupied by the UE, receive control information transmitted by the eNB, wherein the control information is used for controlling whether or not the UE uses the unlicensed carrier resource which has been occupied by the UE; the hardware processor is further configured to send in the local Scell of the UE a Physical Uplink Shared Channel (PUSCED data block which is controlled by no Uplink (UL) scheduling information of the eNB, wherein demodulation information used for the eNB to demodulate the PUSCH data block is fed back to the eNB through a Physical Uplink Control Channel (PUCCH) of a licensed carrier. - View Dependent Claims (16, 17, 18)
