Abstract
A terminal device that communicates with a base station device includes: a higher layer processing unit configured to set an STTI channel setting through signaling of a higher layer from the base station device; and a receiving unit configured to receive a first PDSCH in a case in which the STTI channel setting is not set and receive a second PDSCH in a case in which the STTI channel setting is set. The first PDCCH is mapped to one or more resource blocks, the second PDCCH is mapped to one or more sub resource blocks, and the second PDSCH is demodulated using a reference signal mapped to a symbol including the sub resource block or a resource element before the symbol.

A terminal device that communicates with a base station device, the terminal device comprising:
- circuitry configured to
- set bitmap information indicating resource that can be mapped within a predetermined time domain defined by a plurality of symbols, based on a first upper layer signaling from the base station device;
- set resource block information in a frequency direction to which a channel can be mapped, based on a second upper layer signaling from the base station device, the second upper layer signaling being different from the first upper layer signaling;
- receive the channel which indicates a mapping mode, from the base station device;
- and
- set a first mode or a second mode of the mapping mode,
- wherein the channel is mapped to at least one of one or more channel candidates within the resource which is determined based on the bitmap information and the resource block information,
- wherein a schedule timing in the first mode is performed in units of the predetermined time domain, and a schedule timing in the second mode is performed in units of the symbol.

- transmit a second upper layer signaling to the terminal device, the second upper layer signaling being used to set resource block information, at the terminal device, in a frequency direction to which a channel can be mapped, the second upper layer signaling being different from the first upper layer signaling;
- and
- transmit a physical layer signaling to the terminal device, the terminal device receiving the channel which indicates a mapping mode and setting a first mode or a second mode of the mapping mode,
- wherein the channel is mapped to at least one of one or more channel candidates within the resource which is determined based on the bitmap information and the resource block information,
- wherein a schedule timing in the first mode is performed in units of the predetermined time domain, and a schedule timing in the second mode is performed in units of the symbol.
