Terminal and communication method
In a terminal, based on a first parameter included in each of a plurality of downlink control signals, the first parameter indicating a cumulative count of code block groups (CBGs) configuring each of a plurality of transport blocks (TBs) assigned by the plurality of downlink control signals, a HARQ-ACK generation unit generates a response signal (HARQ-ACK) for each of the code block groups. A transmission unit collectively transmits the response signals for each of the code block groups.
1. A terminal comprising:
circuitry, which, in operation, generates, based on a first parameter included in each of a plurality of downlink control signals, the first parameter indicating a cumulative count of code block groups configuring each of a plurality of transport blocks assigned by the plurality of downlink control signals, a response signal for each of the code block groups; and
a transmitter, which, in operation, collectively transmits the response signals for each of the code block groups, wherein:
each of the plurality of downlink control signals includes the first parameter and a second parameter indicating a setting value of the code block groups assigned by the plurality of downlink control signals, and
a first number of bits used to represent the setting value is greater than a second number of bits used to represent a maximum number of the code block groups assigned by the plurality of downlink control signals.
2. The terminal according to claim 1 , wherein the setting value is larger than a maximum value of the cumulative count of the code block groups.
3. A communication method comprising:
generating, based on a first parameter included in each of a plurality of downlink control signals, the first parameter indicating a cumulative count of code block groups configuring each of a plurality of transport blocks assigned by the plurality of downlink control signals, a response signal for each of the code block groups; and
collectively transmitting the response signals for each of the code block groups, wherein:
each of the plurality of downlink control signals includes the first parameter and a second parameter indicating a setting value of the code block groups assigned by the plurality of downlink control signals, and
a first number of bits used to represent the setting value is greater than a second number of bits used to represent a maximum number of the code block groups assigned by the plurality of downlink control signals.
4. The communication method according to claim 3 , wherein the setting value is larger than a maximum value of the cumulative count of the code block groups.
