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. ## Claims ### Claim 1 An apparatus for wireless communication by a user equipment (UE), comprising: one or more memories; and one or more processors coupled to the one or more memories and configured to: transmit, to a base station, feedback information corresponding to a code block group in conjunction with an indication of a requested redundancy version for a retransmission of the code block group; receive, from the base station, the retransmission of the code block group in response to transmitting the feedback information; and decode the retransmission of the code block group in accordance with the requested redundancy version for the retransmission of the code block group. ### Claim 2 (depends on 1) The apparatus of claim 1, wherein the one or more processors and one or more memories are further configured to: receive, from the base station, a downlink transmission associated with the code block group comprising a plurality of code blocks; and determine that at least one code block of the plurality of code blocks is not processed at the UE, wherein transmitting the indication of the requested redundancy version for the retransmission of the code block group is based at least in part on the determining. ### Claim 3 (depends on 1) The apparatus of claim 1, wherein the one or more processors and one or more memories are further configured to: determine the requested redundancy version for the retransmission of the code block group based at least in part on an incremental redundancy buffer status, wherein transmitting the indication of the requested redundancy version for the retransmission of the code block group comprises transmitting the indication of the determined requested redundancy version. ### Claim 4 (depends on 1) The apparatus of claim 1, wherein the one or more processors and one or more memories are further configured to: determine that a downlink transmission associated with the code block group is scheduled for a set of time periods; refrain from processing the downlink transmission on at least one time period of the set of time periods; and determine the requested redundancy version for the retransmission of the code block group based at least in part on the refraining. ### Claim 5 (depends on 1) The apparatus of claim 1, wherein the one or more processors and one or more memories are further configured to: estimate failure of an upcoming reception of a transport block associated with the code block group; and determine the requested redundancy version for the retransmission of the code block group based at least in part on the estimating. ### Claim 6 (depends on 1) The apparatus of claim 1, wherein to transmit the indication of the requested redundancy version the one or more processors and one or more memories are further configured to: transmit, via uplink control information, the indication of the requested redundancy version for the retransmission of the code block group. ### Claim 7 (depends on 1) The apparatus of claim 1, wherein to transmit the indication of the requested redundancy version the one or more processors and one or more memories are further configured to: transmitting a negative acknowledgement message including the indication of the requested redundancy version for the retransmission of the code block group. ### Claim 8 (depends on 7) The apparatus of claim 7, wherein the negative acknowledgement message comprises a set of bits indicating a starting position in a low-density parity-check code base graph. ### Claim 9 (depends on 1) The apparatus of claim 1, wherein the UE and the base station support four or more than four redundancy versions. ### Claim 10 A method for wireless communication at user equipment (UE), comprising: transmitting, to a base station, feedback information corresponding to a code block group in conjunction with an indication of a requested redundancy version for a retransmission of the code block group; receiving the retransmission of the code block group in response to transmitting the feedback information; and decoding the retransmission of the code block group in accordance with the requested redundancy version for the retransmission of the code block group. ### Claim 11 (depends on 10) The method of claim 10, further comprising: receiving, from the base station, a downlink transmission associated with the code block group comprising a plurality of code blocks; and determining that at least one code block of the plurality of code blocks is not processed at the UE, wherein transmitting the indication of the requested redundancy version for the retransmission of the code block group is based at least in part on the determining. ### Claim 12 (depends on 10) The method of claim 10, further comprising: determining the requested redundancy version for the retransmission of the code block group based at least in part on an incremental redundancy buffer status, wherein transmitting the indication of the requested redundancy version for the retransmission of the code block group comprises transmitting the indication of the determined requested redundancy version. ### Claim 13 (depends on 10) The method of claim 10, further comprising: determining that a downlink transmission associated with the code block group is scheduled for a set of time periods; refraining from processing the downlink transmission on at least one time period of the set of time periods; and determining the requested redundancy version for the retransmission of the code block group based at least in part on the refraining. ### Claim 14 (depends on 10) The method of claim 10, further comprising: estimating failure of an upcoming reception of a transport block associated with the code block group; and determining the requested redundancy version for the retransmission of the code block group based at least in part on the estimating. ### Claim 15 (depends on 10) The method of claim 10, wherein transmitting the indication of the requested redundancy version further comprises: transmitting, via uplink control information, the indication of the requested redundancy version for the retransmission of the code block group. ### Claim 16 (depends on 10) The method of claim 10, wherein transmitting the indication of the requested redundancy version further comprises: transmitting a negative acknowledgement message including the indication of the requested redundancy version for the retransmission of the code block group. ### Claim 17 (depends on 16) The method of claim 16, wherein the negative acknowledgement message comprises a set of bits indicating a starting position in a low-density parity-check code base graph. ### Claim 18 (depends on 10) The method of claim 10, wherein the UE and the base station support four or more than four redundancy versions.
