1. A system, comprising:a processor; and
a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
transmitting first control data from a transmitter device to a receiver device, wherein the first control data comprises a first data structure;
directing, to the receiver device, code block groups that are determined based on a segmentation of a transport block related to the first control data; and
in response to receiving, from the receiver device, a feedback signal that indicates an error during a communication of a code block group of the code block groups,
transmitting, during a first stage, second control data from the transmitter device to the receiver device via a control channel, wherein the second control data is formatted in accordance with the first data structure, and wherein the second control data relates to a length of the transport block; and
transmitting, during a second stage, third control data from the transmitter device to the receiver device via the control channel, wherein the third control data is indicative of the code block group and is formatted in accordance with an adaptable second data structure.
