Patent attributes
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit, via an autonomous uplink communication, one or more transport blocks to a base station. Each transport block may include a plurality of code block groups (CBGs). The base station may provide CBG-level feedback to the UE based at least in part on the autonomous uplink communication. In some examples, the base station may provide the CBG-level feedback in one or more downlink feedback information (DFI) packets. In some other examples, the base station may provide the CBG-level feedback via one or more uplink transmission grants. The UE may retransmit one or more CBGs from the autonomous uplink communication based at least in part on the DFI packets or uplink transmission grants.
