Abstract
A terminal apparatus includes a receiver configured to receive RRC information indicating the maximum number of CBGs X for one transport block in each serving cell; and a generation unit configured to generate X HARQ-ACK bits corresponding to the one transport block, in which the transport block includes NCB code blocks (CBs), in a case that the number of CBs NCB is less than the maximum number of CBGs X, the number of CBGs for the transport block is NCB, and the generation unit generates NCB HARQ-ACK bits for the NCB CBGs and X-NCB NACKs as the X HARQ-ACK bits.
Claims8
A terminal apparatus comprising:
- reception circuitry configured to receive Radio Resource Control (RRC) information for a serving cell;
- and
- generation circuitry configured to:
- in a case that the RRC information does not include a first RRC parameter relating to Code Block Groups (CBGs) transmission for the serving cell, generate 1 Hybrid Automatic Repeat request ACKnowledgement (HARQ-ACK) bit for a transport block, and
- in a case that the RRC information includes the first RRC parameter and also includes a second RRC parameter indicating a maximum number X of CBGs for a transport block for the serving cell, generate X HARQ-ACK bits for the transport block, wherein
- the transport block includes NCB code blocks (CBs),
- in a case that the number NCB of CB is less than the maximum number X of CBGs, the number of CBGs for the transport block is NCB, and
- the generation circuitry generates NCB HARQ-ACK bits for NCB CBGs and X-NCB negative-acknowledgement (NACK) as the X HARQ-ACK bits.
