SPS and multi-PDSCH configuration and DCI for multiple TB case

A method of wireless communication at a base station, comprising:

• transmitting a configuration of a plurality of physical downlink shared channel (PDSCH) occasions including a first PDSCH occasion and a second PDSCH occasion, wherein the configuration includes a bitmap indicating whether each of the plurality of PDSCH occasions is for rate-splitting and a size of the bitmap;
• transmitting a downlink control information (DCI) that indicates at least first transmission parameters for a first type of transport block for a first user equipment (UE) and second transmission parameters for a second type of transport block for rate-splitting with a second UE;
• transmitting the first type of first transport block during the first PDSCH occasion based on the first transmission parameters;
• and
• transmitting the second type of transport block based on the second transmission parameters and a third type of transport block based on third transmission parameters during the second PDSCH occasion.

A user equipment (UE), comprising:

• a transceiver;
• a memory storing computer-executable instructions;
• and
• a processor configured to execute the instructions and cause the UE to:
• receive, via the transceiver, a configuration of a plurality of physical downlink shared channel (PDSCH) occasions including a first PDSCH occasion and a second PDSCH occasion, wherein the configuration includes a bitmap indicating whether each of the plurality of PDSCH occasions is for rate-splitting and a size of the bitmap;
• receive, via the transceiver, a downlink control information (DCI) that indicates at least first transmission parameters for a first type of transport block for the UE and second transmission parameters for a second type of transport block for rate-splitting with a second UE;
• receive, via the transceiver, the first type of transport block during the first PDSCH occasion based on the first transmission parameters;
• and
• receive, via the transceiver, the second type of transport block based on the second transmission parameters and a third type of transport block based on third transmission parameters during the second PDSCH occasion.
