Abstract: A communications device comprising a transmitter configured to transmit signals on communications resources of a wireless access interface of the wireless communications network, a receiver configured to receive signals transmitted on the communications resources of the wireless access interface, and a controller configured to control the transmitter and the receiver to transmit data representing the signals. The controller is configured to determine communications resources of the wireless access interface to be used to transmit the signals representing the data to be transmitted, and to determine a schedule for monitoring the wireless access interface to receive control information, wherein the monitoring schedule is based on the determined communications resources to be used to transmit the data, and the control information is monitored for a pre-emption indication that at least a portion of the determined communications resources are allocated for transmitting signals by another communications device.

Abstract: [Object] To provide a terminal device capable of efficiently performing communication in a communication system in which a base station device and the terminal device communicate with each other.
[Solution] 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.
