Dci design for multi-user superposition transmission

A method of wireless communication by a user equipment (UE), comprising:

• receiving a downlink control information (DCI) message indicating a downlink (DL) grant of a set of resource blocks shared by other UEs for a multi-user multiple-input-multiple-output (MU-MIMO) transmission, the DCI message comprising an MU-MIMO assistance information field;
• receiving the set of resource blocks on at least one spatial layer of the MU-MIMO transmission based on the DL grant;
• and
• processing the set of resource blocks based on the MU-MIMO assistance information field.

An apparatus for wireless communication, comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured to:
• determine to provide a multi-user multiple-input-multiple-output (MU-MIMO) transmission to a plurality of user equipments (UEs) over a same set of resource blocks;
• generate a downlink control information (DCI) message for each UE of the plurality of UEs indicating a downlink (DL) grant of the set of resource blocks, each DCI message comprising an MU-MIMO assistance information field;
• and
• transmit the generated DCI messages to the plurality of UEs.
