Abstract
Certain aspects of the present disclosure provide techniques for downlink retransmission of Code Block Groups (CBGs) in the event of preemption.
Claims22
A method for wireless communication by a user equipment (UE), comprising:
- receiving a preemption indication, from a base station, indicating one or more code block groups (CBGs) affected by downlink physical resource preemption;
- receiving a downlink control information (DCI) transmission scheduling a subsequent transmission of the one or more CBGs and including a checksum generated as a function of the preemption indication;
- reconfirming the one or more CBGs affected by downlink physical resource preemption based on a comparison of the received checksum and a checksum generated based on the received preemption indication;
- and
- processing the subsequent transmission of the one or more CBGs based on the reconfirmation.
