Facilitating notifications to indicate failed code block groups is provided herein. A method can comprise determining a value of a confirmation bit received in a transmission based on a first determination that a new data indicator is set to a null indication and performing an action from a group of actions. The group of actions can comprise decoding a first group of code block groups of the code block groups based on a second determination that the value of the confirmation bit for the first group of code block groups is a first value. The group of actions can also comprise decoding the code block groups based on a third determination that the value of the confirmation bit for the code block groups is set to a second value and sending a report indicating at least one of the code block groups for which the transmission failed.
