1. An apparatus for wireless communication at a first user equipment (UE), comprising:
memory; and
one or more processors coupled to the memory, the one or more processors configured to cause the first UE to:
obtain configuration information associated with a flush indicator (FI), the configuration information indicating a length of the FI in one or more sidelink transmissions;
transmit a first transmission of the one or more sidelink transmissions to a second UE, the first transmission including one or more code blocks (CBs);
transmit, to the second UE, a retransmission of at least one code block (CB) of the one or more CBs; and
transmit, via sidelink, the FI to the second UE based on the configuration information, the FI indicating to the second UE to avoid combining a prior transmission of the at least one CB with the retransmission of the at least one CB.
