Patent ID: 10574405

Abstract:
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)
