A system and a method are disclosed for processing data to be mapped into a transport block transmitted over a wireless physical shared channel. In one embodiment, a code block determination circuit determines a size of a code block of data that maps across at least one slot boundary of a slot of the wireless physical shared channel. A rate matching circuit rate matches bits of a code block to a number of bits available in the transport block that spans one or more slots of the wireless physical shared channel. An interleaver interleaves an output of the rate matching circuit so that a code block that crosses a slot boundary between a first slot and a second slot is interleaved between the first slot and the second slot.
