摘要： A cell using an unallocated frequency band or a shared frequency band is efficiently controlled. A terminal device includes a reception unit configured to receive a first downlink physical channel mapped on the basis of a first possible starting position of a downlink transmission and a second downlink physical channel mapped on the basis of a second possible starting position of the downlink transmission. Upon the first possible starting position and the second possible starting position being indicated by a higher layer, the reception unit receives, in a predetermined subframe, either one of the first downlink physical channel or the second downlink physical channel, on a secondary cell having a frame structure type 3.

摘要： There is provided a terminal for performing OFDM (Orthogonal Frequency-Division Multiplexing) communication with a base station forming a cell. The terminal includes a control channel processing unit configured to monitor, in a sub-frame, a first control channel in a cell-specific search space that is a search space common within the cell, and a first control channel in a UE-specific search space that is a search space specific to the terminal. In a case where monitoring of a second control channel different from the first control channel that is in the cell-specific search space or the UE-specific search space is configured, the control channel processing unit monitors, in a sub-frame, at least both the first control channel in the cell-specific search space and the second control channel in the UE-specific search space.

摘要： There is provided a terminal device which includes a transmission unit that transmits HARQ response information to a first serving cell and a second serving cell on a physical uplink shared channel in a subframe n. The physical uplink shared channel is transmitted based on a physical downlink control channel or an enhanced physical downlink control channel which is detected in a state of including a downlink control information format 0/4. Two or more serving cells are configured in the terminal device, in a case where frame constitution types of any two configured serving cells are different from each other, and in a case where a primary cell has Frame constitution type 2, BcDL is applied to the first serving cell of Frame constitution type 2 by using the following expression (1), and is applied to the second serving cell of Frame constitution type 1 by using the following expression (2).[Math. 1] BcDL=min(WDAIUL,Mc) Expression (1) [Math. 2] BcDL=min(WDAIUL+4┌(U−WDAIUL)/4┐,Mc) Expression (2)

摘要： A terminal device including a reception unit configured to receive higher layer signalling including a first configuration relating to measurement of a Received Signal Strength Indicator (RSSI) and a second configuration relating to reporting of the RSSI, a measurement unit configured to measure the RSSI and/or a channel occupancy; and a transmission unit configured to report a measurement result for the RSSI and/or the channel occupancy. The measurement result for the RSSI is an average of measurement results obtained in a first period, and the channel occupancy is obtained based on the measurement results equal to or greater than a first threshold among the measurement results obtained in the first period.

摘要： There is provided a terminal device capable of efficiently performing communication in a communication system in which a base station device and the terminal device communicate with each other. The terminal device that communicates with the base station device by using a plurality of aggregated cells recognizes that a serving cell is stopped in a first state, recognizes that the serving cell is started in a second state, and switches from the first state to the second state based on a received PDCCH.

摘要： To efficiently control a cell by using a non-allocated frequency band or a shared frequency band. A terminal device includes a transmission unit configured to transmit a PUSCH and a CCA check unit configured to perform LBT before a subframe for which a transmission of the PUSCH is indicated. The terminal device determines start time of the LBT, based on start time of the transmission of the PUSCH, a CCA slot length, and the number of CCA checks. The terminal device includes a reception unit configured to receive a PDCCH. The number of CCA checks is indicated on the PDCCH.
