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.
