Abstract

A terminal device communicating with a base station device transmits an HARQ-ACK with respect to PDSCH on a serving cell in a first cell group by using a PUCCH on a first serving cell in the first cell group, transmits an HARQ-ACK with respect to a PDSCH on a serving cell in a second cell group by using a PUCCH on a second serving cell in the second cell group, and transmits, to the base station device, information including first information indicating whether to support CA using UL-DL configuration combinations different between a serving cell in a first band and a serving cell in a second band in the first cell group, and second information indicating whether to support CA using UL-DL configuration combinations different between the serving cell in the first band and a serving cell in the second cell group.
