Abstract
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a transmission comprising an indication of at least one failed code block group in a plurality of code block groups, wherein a code block group comprises a plurality of code blocks, re-assign code blocks to different code block groups (CBGs) according to a total number of code blocks (CBs) across the at least one failed code block group (CBG) and a maximum number of code block groups (CBGs) per a transport block (TB), and configure a retransmission based on the re-assigned code blocks (CBs).
Claims24
A method for wireless communication at a user equipment (UE), comprising:
- receiving a transmission comprising an indication of a failed decoding for at least one code block group (CBG) of a plurality of CBGs, wherein a CBG comprises a plurality of code blocks (CBs);
- and
- generating a hybrid automatic repeat request (HARQ) feedback for at least one failed CB from the CBG, wherein the UE sends the HARQ feedback for the failed CB from the CBG when the CBG is scheduled based on a code block group transmission indicator (CBGTI) and does not send the HARQ feedback when the CBG is not scheduled based on the CBGTI.
A method for wireless communication at a base station (BS), comprising:
- receiving a transmission comprising an indication of at least one failed code block group (CBG) in a plurality of CBGs, wherein a CBG comprises a plurality of code blocks (CBs);
- and
- generating a code block group transmission indicator (CBGTI) for at least one failed CB from the CBG, wherein the BS receives a hybrid automatic repeat request (HARQ) feedback during a retransmission of the failed CB when the CBG is scheduled based on the CBGTI and does not receive the HARQ feedback when the CBG is not scheduled based on the CBGTI.
A user equipment (UE), comprising:
- a memory;
- and
- a processor coupled to the memory, the processor being configured to:
- receive a transmission comprising an indication of a failed decoding for at least one code block group (CBG) of a plurality of CBGs, wherein a CBG comprises a plurality of code blocks (CBs);
- and
- generate a hybrid automatic repeat request (HARQ) feedback for at least one failed CB from the CBG, wherein the processor sends the HARQ feedback for the failed CB from the CBG when the CBG is scheduled based on a code block group transmission indicator (CBGTI) and does not send the HARQ feedback when the CBG is not scheduled based on the CBGTI.
A base station (BS), comprising:
- a memory;
- and
- a processor coupled to the memory, the processor being configured to:
- receive a transmission comprising an indication of at least one failed code block group (CBG) in a plurality of CBGs, wherein a CBG comprises a plurality of code blocks (CBs);
- and
- generate a code block group transmission indicator (CBGTI) for at least one failed CB from the CBG, wherein the processor receives a hybrid automatic repeat request (HARQ) feedback during a retransmission of the failed CB when the CBG is scheduled based on the CBGTI and does not receive the HARQ feedback when the CBG is not scheduled based on the CBGTI.
A base station (BS), comprising:
- means for receiving a transmission comprising an indication of a failed decoding for at least one code block group (CBG) of a plurality of CBGs, wherein a code block group comprises a plurality of code blocks (CBs);
- and
- means for generating a code block group transmission indicator (CBGTI) for at least one failed CB from the CBG, wherein the BS receives a hybrid automatic repeat request (HARQ) feedback during a retransmission of the failed CB when the CBG is scheduled based on the CBGTI and does not receive the HARQ feedback when the CBG is not scheduled based on the CBGTI.
A user equipment (UE), comprising:
- means for receiving a transmission comprising an indication of at least one failed code block group (CBG) in a plurality of CBGs, wherein a CBG comprises a plurality of code blocks (CBs);
- and
- means for generating a hybrid automatic repeat request (HARQ) feedback for at least one failed CB from the CBG, wherein the user equipment sends the HARQ feedback for the failed CB from the CBG when the CBG is scheduled based on a code block group transmission indicator (CBGTI) and does not send the HARQ feedback when the CBG is not scheduled based on the CBGTI.
