Vehicle-to-everything communications using network coding assisted by a relay

A user equipment (UE) for wireless communication, comprising:

• a memory;
• and
• one or more processors operatively coupled to the memory, the memory and the one or more processors configured to:
• transmit, to another UE, a set of encoded packets associated with a vehicle-to-everything (V2X) communication, wherein the set of encoded packets are generated according to a network coding scheme;
• transmit, to a relay device, the set of encoded packets associated with the V2X communication;
• and
• receive, from the relay device, an acknowledgment message based at least in part on transmitting, to the relay device, the set of encoded packets associated with the V2X communication;
• stop the transmission, to the other UE, of the set of encoded packets associated with the V2X communication based at least in part on receiving the acknowledgement message from the relay device;
• and
• stop the transmission, to the relay device, of the set of encoded packets associated with the V2X communication based at least in part on receiving the acknowledgement message from the relay device.

A method of wireless communication performed by a relay device, comprising:

• receiving, from a first user equipment (UE), a first vehicle-to-everything (V2X) communication;
• receiving, from a second UE, a second V2X communication, wherein the first V2X communication and the second V2X communication are intended for a third UE;
• transmitting, to the third UE, a set of encoded packets associated with the first V2X communication and the second V2X communication, wherein the set of encoded packets are generated according to a network coding scheme;
• receiving, from the first UE, a set of encoded packets associated with the first V2X communication, wherein the set of encoded packets are generated according to a network coding scheme;
• decoding the set of encoded packets to form a set of source packets associated with the first V2X communication according to the network coding scheme;
• and
• transmitting, to the first UE, an acknowledgment message based at least in part on a determination that the set of source packets associated with the first V2X communication were determined from the set of encoded packets successfully.
