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.
Claims15
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.
A base station device that communicates with a terminal device, the base station device comprising:
- circuitry configured to transmit to the terminal device:
- 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, receive response information relative to the downlink data channel from the terminal device 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 received via the first uplink control channel,
- based on the priority information indicating a low priority, the response information is received via the second uplink control channel,
- wherein, the response information that is received via the first uplink control channel or the second uplink control channel is repeated in a configured number of slots.
A communication method performed by a terminal device that communicates with a base station device, the communication method comprising:
- receiving, 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, transmitting 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,
- wherein, 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.
A communication method performed by a base station device that communicates with a terminal device, the communication method comprising:
- transmitting to the terminal device:
- 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, receiving response information relative to the downlink data channel from the terminal device 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 received via the first uplink control channel,
- based on the priority information indicating a low priority, the response information is received via the second uplink control channel,
- wherein, the response information that is received via the first uplink control channel or the second uplink control channel is repeated in a configured number of slots.
