Abstract
An operation method of a source terminal for sidelink communication may comprise transmitting at least two transport blocks (TBs) or code block groups (CBGs) to a destination terminal; receiving hybrid automatic repeat request-acknowledgement/negative acknowledgement (HARQ-ACK/NACK) bits for the at least two TBs or CBGs from the destination terminal; generating an HARQ codebook based on the HARQ-ACK/NACK bits; and reporting the generated HARQ codebook to a serving base station.
Claims20
An operation method of a source terminal for sidelink communication, the operation method comprising:
- transmitting at least two transport blocks (TBs) or code block groups (CBGs) to a destination terminal;
- receiving hybrid automatic repeat request-acknowledgement/negative acknowledgement (HARQ-ACK/NACK) bits for the at least two TBs or CBGs from the destination terminal;
- generating an HARQ codebook based on the HARQ-ACK/NACK bits;
- and
- reporting the generated HARQ codebook to a serving base station.
An operation method of a destination terminal for sidelink communication, the operation method comprising:
- receiving at least two transport blocks (TBs) or code block groups (CBGs) from a source terminal;
- and
- transmitting hybrid automatic repeat request-acknowledgement/negative acknowledgement (HARQ-ACK/NACK) bits for the at least two TBs or CBGs to the source terminal.
An operation method of a serving base station for sidelink communication, the operation method comprising:
- configuring, to a source terminal, transmission of at least two transport blocks (TBs) or code block groups (CBGs) for a destination terminal;
- and
- receiving, from the source terminal, a report of hybrid automatic repeat request-acknowledgement/negative acknowledgement (HARQ-ACK/NACK) bits for the at least two TBs or CBGs that the source terminal receives from the destination terminal.
