1. A method of wireless communication performed by a user equipment (UE), comprising:
determining a number of resource elements (REs) associated with downlink control information (DCI) that is to be carried on a physical downlink shared channel (PDSCH) with a shared channel, wherein the number of REs associated with the DCI is determined based at least in part on combining a number of REs associated with the shared channel, a payload size of the shared channel, a payload size of the DCI, and a scaling factor for scaling a total number of REs of a resource allocation for the DCI;
determining a remaining number of REs, of the number of REs associated with the shared channel, by subtracting the number of REs associated with the DCI from the number of REs associated with the shared channel;
determining a transport block size (TBS) for the shared channel based at least in part on the remaining number of REs, of the number of REs associated with the shared channel, wherein the TBS for the shared channel is a modified TBS;
wherein determining the TBS for the shared channel further comprises:
determining an initial TBS based at least in part on the number of REs associated with the shared channel and a modulation and coding scheme (MCS) of the shared channel; and
wherein the modified TBS is determined based at least in part on the remaining number of REs and the MCS of the shared channel;
and
receiving the PDSCH based at least in part on the TBS for the shared channel.
