Abstract: The apparatus, which may be a receiving device, is disclosed. The apparatus may receive at least one HARQ retransmission of at least one first bit. The HARQ retransmission may be associated with an MLC scheme including MSD. The MLC scheme may include a plurality of bits with the at least one first bit and at least one second bit. The apparatus may decode the at least one first bit of the MLC scheme based on the at least one HARQ retransmission. The apparatus may determine whether the at least one first bit of the MLC scheme is decoded successfully. The apparatus may decode, upon determining that the at least one first bit of the MLC scheme is decoded successfully, the at least one second bit of the MLC scheme based on at least one ARQ retransmission of the at least one second bit.

Abstract: Methods, systems, and devices for latency minimization in wireless communications employing multi-level coding and multi-level sequential demodulation and decoding are described. A user equipment (UE) receive a set of codeblock groups in a first time period. Each codeblock group jointly sharing same channel resources may be associated with a respective decoding level of a set of decoding levels. The UE may determine a first outcome for a first codeblock group and a second outcome for a second codeblock group. The UE may then transmit a feedback message that is based on the first outcome and the second outcome. In case that the feedback message indicates that the first outcome or the second outcome is a failed decoding procedure, the UE may receive, in a second time period, a retransmission of all the codeblock groups. These retransmissions may continue on additional time periods until all related codeblock groups are successfully decoded.

Abstract: Methods, systems, and devices for wireless communications employing multi-level coding with set partitioning on transmitting side and multi-level sequential decoding on the receiving side for latency minimization are described. In some systems, a transmitting device may transmit a code block group (CBG) to a receiving device including a first set of code blocks associated with a first decoding level and a second set of code blocks associated with a second decoding level. The receiving device may unsuccessfully decode one or more code blocks of the first set or the second set of code blocks and transmit a feedback message to the transmitting device. The transmitting device may determine that the data to be communicated via the CBG is latency-sensitive data and, as such, determine to retransmit both the first set and the second set of code blocks to the receiving device in response to receiving the feedback message.
