Reporting redundancy version with feedback information
Methods, systems, and devices for reporting redundancy version with feedback information. are described. A user equipment (UE) may transmit, to a base station, feedback information corresponding to a code block group in conjunction with an indication of a redundancy version for retransmission of the code block group. The UE may monitor for the retransmission of the code block group based on the indication of the redundancy version for the retransmission of the code block group. The UE may then decode the retransmission of the code block group based on the monitoring and the redundancy version for the retransmission of the code block group.
1 . An apparatus for wireless communication at a network entity, comprising:
one or more memories storing processor-executable code; and
one or more processors coupled with the one or more memories and operable to execute the code to cause the apparatus to:
receive, from a user equipment (UE), feedback information corresponding to a code block group in conjunction with an indication of a redundancy version for a retransmission of the code block group; and
transmit, to the UE, the retransmission of the code block group based at least in part on receiving the indication of the redundancy version for the retransmission of the code block group.
2 . The apparatus of claim 1 , wherein the one or more processors are further operable to cause the apparatus to:
transmit, to the UE, a downlink transmission associated with the code block group comprising a plurality of code blocks, wherein receiving the indication of the redundancy version for the retransmission of the code block group is based at least in part on at least one code block of the plurality of code blocks not being processed at the UE.
3 . The apparatus of claim 1 , wherein, to receive the indication of the redundancy version, the one or more processors are further operable to cause the apparatus to:
receive the indication of the redundancy version for the retransmission of the code block group based at least in part on an incremental redundancy buffer status at the UE.
4 . The apparatus of claim 1 , wherein, to receive the indication of the redundancy version, the one or more processors are further operable to cause the apparatus to:
receive, via uplink control information, the indication of the redundancy version for the retransmission of the code block group.
5 . The apparatus of claim 1 , wherein, to receive the indication of the redundancy version, the one or more processors are further operable to cause the apparatus to:
receive a negative acknowledgement message including the indication of the redundancy version for the retransmission of the code block group.
6 . The apparatus of claim 5 , wherein the negative acknowledgement message comprises a set of bits indicating a starting position in a low-density parity-check code base graph.
7 . The apparatus of claim 1 , wherein the UE and the network entity support four or more than four redundancy versions.
8 . A method for wireless communication at a network entity, comprising:
receiving, from a user equipment (UE), feedback information corresponding to a code block group in conjunction with an indication of a redundancy version for a retransmission of the code block group; and
transmitting, to the UE, the retransmission of the code block group based at least in part on receiving the indication of the redundancy version for the retransmission of the code block group.
9 . The method of claim 8 , further comprising:
transmitting, to the UE, a downlink transmission associated with the code block group comprising a plurality of code blocks, wherein receiving the indication of the redundancy version for the retransmission of the code block group is based at least in part on at least one code block of the plurality of code blocks not being processed at the UE.
10 . The method of claim 8 , wherein receiving the indication of the redundancy version further comprises:
receiving the indication of the redundancy version for the retransmission of the code block group based at least in part on an incremental redundancy buffer status at the UE.
11 . The method of claim 8 , wherein receiving the indication of the redundancy version further comprises:
receiving, via uplink control information, the indication of the redundancy version for the retransmission of the code block group.
12 . The method of claim 8 , wherein receiving the indication of the redundancy version further comprises:
receiving a negative acknowledgement message including the indication of the redundancy version for the retransmission of the code block group.
13 . The method of claim 12 , wherein the negative acknowledgement message comprises a set of bits indicating a starting position in a low-density parity-check code base graph.
14 . The method of claim 8 , wherein the UE and the network entity support four or more than four redundancy versions.
15 . An apparatus for wireless communication at a network entity, comprising:
means for receiving, from a user equipment (UE), feedback information corresponding to a code block group in conjunction with an indication of a redundancy version for a retransmission of the code block group; and
means for transmitting, to the UE, the retransmission of the code block group based at least in part on receiving the indication of the redundancy version for the retransmission of the code block group.
16 . The apparatus of claim 15 , further comprising:
means for transmitting, to the UE, a downlink transmission associated with the code block group comprising a plurality of code blocks, wherein receiving the indication of the redundancy version for the retransmission of the code block group is based at least in part on at least one code block of the plurality of code blocks not being processed at the UE.
17 . The apparatus of claim 15 , wherein the means for receiving the indication of the redundancy version further comprise:
means for receiving the indication of the redundancy version for the retransmission of the code block group based at least in part on an incremental redundancy buffer status at the UE.
