A terminal apparatus comprising: a MAC, Medium Access Control, layer processing unit configured to initiate a random access procedure on a first serving cell, and initiate a random access procedure on a second serving cell, and in a case in which at least one scheduling request is pending, no UL-SCH, uplink shared channel, resources are available for a transmission, a PUCCH, Physical Uplink Control Channel, resource for the scheduling request is configured only on the second serving cell, and a value of a counter is smaller than a predetermined value, increment the value of the counter by 1 and instruct a transmission unit to transmit the scheduling request on the PUCCH; and the transmission unit configured to transmit the scheduling request on the PUCCH on the second serving cell, wherein the MAC layer processing unit is further configured to, in a case in which at least one scheduling request is pending, no UL-SCH resources are available for the transmission, the PUCCH resource for the scheduling request is configured only on the second serving cell, and the second serving cell is deactivated, initiate the random access procedure on the first serving cell out of the first serving cell and the second serving cell, the first serving cell being indicated in a handover procedure and the PUCCH resource for the scheduling request being configured on the second serving cell, the transmission unit is further configured to: in a case that a positive scheduling request transmission with PUCCH format 1a/1b and a HARQ-ACK transmission with PUCCH format 1a/1b occur in a subframe in different serving cells, transmit the HARQ-ACK in the subframe on PUCCH resource for the HARQ-ACK in one of the different serving cells and transmit the positive scheduling request in the subframe on PUCCH resource for the positive scheduling request in the other of the different serving cells, and in a case that a positive scheduling request transmission with PUCCH format 1a/1b and a HARQ-ACK transmission with PUCCH format 1a/1b occur in a subframe in the same serving cell, transmit the HARQ-ACK in the subframe on PUCCH resource for the positive scheduling request in the same serving cell. a MAC, Medium Access Control, layer processing unit configured to initiate a random access procedure on a first serving cell, and initiate a random access procedure on a second serving cell, and in a case in which at least one scheduling request is pending, no UL-SCH, uplink shared channel, resources are available for a transmission, a PUCCH, Physical Uplink Control Channel, resource for the scheduling request is configured only on the second serving cell, and a value of a counter is smaller than a predetermined value, increment the value of the counter by 1 and instruct a transmission unit to transmit the scheduling request on the PUCCH;
