1. An apparatus for wireless communication at a user equipment (UE), comprising:
at least one memory; and
at least one processor coupled to the at least one memory and configured to:
receive at least one downlink (DL) grant after a reception of an uplink (UL) grant, the at least one DL grant being associated with a DL current downlink assignment index (cDAI) value and a DL total downlink assignment index (tDAI) value, the DL cDAI value being a counter value, the UL grant being associated with an UL tDAI value and scheduling a plurality of physical uplink shared channel (PUSCH) repetitions;
calculate a total number of DL grants sent to the UE based on the DL cDAI value;
adjust the total number of DL grants if there is a difference between the total number of DL grants and the UL tDAI value; and
transmit a hybrid automatic repeat request (HARQ) codebook associated with the at least one DL grant in at least one of the plurality of PUSCH repetitions, a size of the HARQ codebook being based on the adjusted total number of DL grants.
