A terminal apparatus for communicating with a base station apparatus by using at least two serving cells including one primary cell configured with Frequency Division Duplex, FDD, and one secondary cell configured with Time Division Duplex, TDD, in 3 rd Generation Partnership Project, 3GPP, Long Term Evolution, LTE, communications, the terminal apparatus comprising: a receiver configured to receive a Physical Downlink Control Channel, PDCCH, scrambled by a Cell-Radio Network Temporary Identifier, C-RNTI, and one or two transport blocks scheduled by the PDCCH in the primary cell; and a transmitter configured to transmit Hybrid Automatic Repeat request-ACKnowledgement, HARQ-ACK, for the one or two transport blocks, select a first transmission method in a case that a scheduling request, SR, is a positive scheduling request, the one or two transport blocks are received in the primary cell in a subframe i, the HARQ-ACK and the scheduling request are transmitted in subframe i+kpp, and a subframe j in the secondary cell does not correspond to any of first prescribed subframes, select a second transmission method in a case that the scheduling request is the positive scheduling request, the one or two transport blocks are received in the primary cell in the subframe i, the HARQ-ACK and the scheduling request are transmitted in subframe i+kpp, and the subframe j in the secondary cell corresponds to one of the first prescribed subframes, and transmit the HARQ-ACK in a PUCCH resource for the scheduling request, by using the transmission method selected, wherein the first transmission method is a method for transmitting the HARQ-ACK and the SR with PUCCH format 1b with channel selection for FDD, the second transmission method is a method for transmitting the HARQ-ACK and the SR with PUCCH format 1a or 1b for FDD, wherein the subframe j is given by i - 1 in a case that a higher layer parameter shortProcessingTime for the primary cell is configured, a higher layer parameter shortProcessingTime for the secondary cell is not configured, and the PDCCH is received in a User Equipment-specific Search Space, USS, in subframe i, the subframe j is given by i + 1 in a case that the higher layer parameter shortProcessingTime for the primary cell is configured, the higher layer parameter shortProcessingTime for the secondary cell is configured, and the PDCCH is received in a common search space, CSS, in subframe i, kpp is 4 if the higher layer parameter shortProcessingTime for the primary cell is not configured, kpp is 3 if the higher layer parameter shortProcessingTime for the primary cell is configured, and the first prescribed subframes includes uplink subframes, special subframes with TDD frame configuration 0 or 5 when normal Cyclic Prefix, CP, is configured for downlink, and special subframes with TDD frame configuration 0 or 4 when extended CP is configured for the downlink. a receiver configured to receive a Physical Downlink Control Channel, PDCCH, scrambled by a Cell-Radio Network Temporary Identifier, C-RNTI, and one or two transport blocks scheduled by the PDCCH in the primary cell;
