說明書
UE is capable of establishing an RRC connection in an LTE serving cell of a licensed band in operation 3703. After that, the UE is capable of determining whether it receives a control message enquiring an unlicensed band capability report from the ENB in operation 3705. When the UE receives, from the ENB, a control message enquiring an unlicensed band capability report in operation 3705, it is capable of reporting, to the ENB, a condition as to whether it supports an unlicensed band LTE operation and an unlicensed band LTE duplex mode (TDD or FDD) in operation 3707. For example, the capability report enquiring control message can include a UECapabilityEnquiry message of the RRC layer. The report message can include a UECapabilityInformation message of the RRC layer. The enquiry message can include a frequency band indicator specifying an unlicensed band, and information indicating an operation mode of an unlicensed band. Meanwhile, the report control message can include information indicating a frequency band supported by the UE. The UE is capable of reporting only a frequency band indicator for a licensed band; however, it can report a frequency band indicator and duplex mode information for an unlicensed band. This is because the frequency band indicator does not include duplex mode.
