Abstract
Methods, systems, and devices for wireless communications are described. A base station may transmit a set of code blocks to multiple user equipments (UEs). The base station may receive feedback pertaining to reception of each of the set of code blocks at each of the multiple UEs. The base station may generate, based on the feedback, a retransmission message that includes encoded data representative of a subset of code blocks of the set of code blocks and additional redundancy with respect to the subset of code blocks. The multiple UEs may receive the retransmission message and extract a portion corresponding the set of code blocks that were previously unsuccessfully decoded. The UEs may combine the portion of the set of code blocks with the unsuccessfully decoded code blocks to create an updated combined versions of the code blocks. The UEs may decode the combined versions of the code blocks.
