1. A method of wireless communication by a receiving sidelink user equipment (UE), comprising:
receiving a first original message from a first transmitting sidelink UE;
receiving, from a network coding device, a network coded (NC) packet that is coded across the first original message and a second original message from a second transmitting sidelink UE, the first original message corresponding to a first transport block, the second original message corresponding to a second transport block;
transmitting a first negative acknowledgment (NACK) in response to the first transport block being unsuccessfully decoded;
transmitting a second NACK in response to the second transport block being unsuccessfully decoded; and
transmitting a first acknowledgment (ACK) in response to the first transport block being successfully decoded.
 
13. A method of wireless communication by a network coding device, comprising:
transmitting, to a receiving device, a network coded (NC) packet that is coded across a first original message originating from a first transmitting sidelink user equipment (UE) and a second original message originating from a second transmitting sidelink UE, the first original message corresponding to a first transport block the second original message corresponding to a second transport block;
receiving a first negative acknowledgment (NACK) in response to the first transport block being unsuccessfully decoded;
receiving a second NACK in response to the second transport block being unsuccessfully decoded; and
receiving a first acknowledgment (ACK) in response to the first transport block being successfully decoded.
 
24. An apparatus for wireless communication by a receiving sidelink user equipment (UE), comprising:
a memory; and
at least one processor coupled to the memory, the at least one processor configured:
to receive a first original message from a first transmitting sidelink UE;
to receive, from a network coding device, a network coded (NC) packet that is coded across the first original message and a second original message from a second transmitting sidelink UE, the first original message corresponding to a first transport block, the second original message corresponding to a second transport block;
to transmit a first negative acknowledgment (NACK) in response to the first transport block being unsuccessfully decoded;
to transmit a second NACK in response to the second transport block being unsuccessfully decoded; and
to transmit a first acknowledgment (ACK) in response to the first transport block being successfully decoded.
