Patent ID: 11515968

Abstract:
Methods, systems, and devices for wireless communications are described. The following relates more specifically to hierarchical hybrid automatic repeat request (HARM) for multi-level coding with multi-level sequential demodulation and decoding and code block grouping per decoding level. A user equipment (UE) may receive, during a first time period, a transmission from a base station including a first and second code block group (CBG) with codeblocks associated with a first and second decoding level. The UE may fail to decode the first CBG, may not decode the second CBG, may store post processing samples for the second CBG, and may transmit a feedback message to the base station. The base station may retransmit the first CBG and new data on the second CBG in a second time period. The UE may decode the first CBG and use the post processing samples to decode the second CBG from the first time period.
