29. A method of wireless communication at a user equipment (UE), comprising:
receiving a first indication of a mapping of a plurality of layers to a first common codeword (c-CW) and a first private codeword (p-CW) from a network entity, wherein the first indication indicates the first c-CW corresponds to at least one first layer of the plurality of layers and the first p-CW corresponds to at least one second layer of the plurality of layers, wherein the plurality of layers is associated with multiple input-multiple output (MIMO) communication, wherein the first c-CW and the first p-CW are associated with rate-splitting for the MIMO communication;
identifying a first set of modulated symbols of the first c-CW that is mapped to the at least one first layer and a second set of modulated symbols of the first p-CW that is mapped to the at least one second layer based on the first indication; and
performing a decoding process for at least one of the first c-CW or the first p-CW based on at least one of the first set of modulated symbols or the second set of modulated symbols.
 
30. A method of wireless communication at a network entity, comprising:
mapping a plurality of layers to a first common codeword (c-CW) and a first private codeword (p-CW), wherein a first set of modulated symbols of the first c-CW is mapped to at least one first layer of the plurality of layers and a second set of modulated symbols of the first p-CW is mapped to at least one second layer of the plurality of layers, wherein the plurality of layers is associated with multiple input-multiple output (MIMO) communication, wherein the first c-CW and the first p-CW are associated with rate-splitting for the MIMO communication; and
transmitting a first indication of the mapping of the plurality of layers to the first c-CW and the first p-CW for a first user equipment (UE), wherein the first indication indicates that the first c-CW corresponds to the at least one first layer and the first p-CW corresponds to the at least one second layer.
