說明書
When receiving the measurement instructing control message, the UE is capable of transmitting an acknowledgement message that the measurement instructing control message has been received to the ENB in operation and measuring the unlicensed band according to the information in the control message in operation 3411. According to the received, parameter(s), the UE is capable of: obtaining information regarding cells with PCIs according to frequencies, information regarding duplex mode (FDD or TDD) where corresponding cells are measured, and also a time that a C-RS or D-RS for a corresponding cell is measured; and measuring the configured unlicensed band frequency. Measuring an unlicensed band operating in FDD mode means that: in a state where the forward sub-frame structure of cells of a corresponding band follows a particular pattern, UE detects that the pattern of sub-frames transmitting PSS/SSS signals also follows the FDD operation mode, specifies a time interval when signals required for measurement will be received, and performs measurement in the corresponding time interval. In addition, measuring an unlicensed band operating in TDD mode means that: in a state where the forward sub-frame structure of cells of a corresponding band follows another particular pattern, UE detects that the pattern of sub-frames transmitting PSS/SSS signals also follows the TDD operation mode, specifies a time interval when signals required for measurement will be received, and performs measurement in the corresponding time interval.
