Terminal device, base station device, communication method, and storage medium

Abstract

To greatly improve transmission efficiency of an entire system by improving reliability while ensuring low delay with respect to notification of response information in a communication system in which a base station device and a terminal device communicate with each other.A terminal device that communicates with a base station device, the terminal device including: a reception unit that receives a data channel including one or more pieces of data; and a transmission unit that transmits response information to the data on the basis of a parameter regarding reliability of the data.

1 . A terminal device that communicates with a base station device, the terminal device comprising:
 circuitry configured to:
 receive, from the base station:
 a downlink control channel including scheduling information and priority information, and 
 a downlink data channel including at least one of first data or second data, based on the scheduling information; and 
 
 based on the priority information, transmit response information relative to the downlink data channel to the base station via a first uplink control channel or a second uplink control channel, 
 wherein:
 based on the priority information indicating a high priority, the response information is transmitted via the first uplink control channel, 
 based on the priority information indicating a low priority, the response information is transmitted via the second uplink control channel, and 
 the response information that is transmitted via the first uplink control channel or the second uplink control channel is repeated in a configured number of slots.
