Control signaling for sic in nr 2-codeword operating mode

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

• transmitting, to a network entity, a successive interference cancellation (SIC) capability indication comprising an indication that the UE supports a SIC operation and an order of processing a first codeword and a second codeword;
• monitoring for an acknowledgement (ACK) to enable the SIC operation between the UE and the network entity;
• and
• receiving downlink communication based on the SIC operation in response to receiving the ACK to enable the SIC operation.

An apparatus for wireless communication at a network entity, comprising:

• a memory;
• and
• at least one processor coupled to the memory and, based at least in part on information stored in the memory, the at least one processor is configured to:
• obtain a successive interference cancellation (SIC) capability indication comprising an indication that a user equipment (UE) supports a SIC operation and an order of processing a first codeword and a second codeword;
• output an acknowledgement (ACK) to enable the SIC operation between the UE and the network entity;
• and
• output downlink communication based on the SIC operation in response to the outputting the ACK to enable the SIC operation.
