Transport block segmentation and signaling

An apparatus for wireless communications, comprising:

• a processor;
• and
• memory coupled to the processor, wherein the processor is configured to:
• receive an indication associated with a reference number of resources for an overhead channel based at least in part on a communication link direction associated with the overhead channel, wherein the communication link direction comprises uplink or downlink,
• determine a number of resources available for data transmission based at least in part on the reference number of resources for the overhead channel,
• determine a size of a transport block based at least in part on the number of resources available for data transmission,
• segment the transport block into at least one code block based at least in part on the size of the transport block, and
• communicate the at least one code block over a communication link.
