Outer coding header for ran-based network coding

A method of wireless communication at a wireless device, comprising:

• segmenting each packet data convergence protocol (PDCP) packet in a plurality of PDCP packets into a set of outer coding (OC) symbols, wherein the plurality of PDCP packets corresponds to a packet data unit (PDU) set;
• assembling multiple sets of OC symbols into an OC block;
• applying a forward error correction (FEC) encoding to the OC block;
• and
• outputting the OC block based on the FEC encoding.

An apparatus for wireless communication at a wireless device, comprising:

• at least one memory;
• and
• at least one processor coupled to the at least one memory and, based at least in part on information stored in the at least one memory, the at least one processor, individually or in any combination, is configured to:
• assemble one or more outer coding (OC) symbols of a packet data unit (PDU) set into a set of OC blocks, wherein the PDU set includes a plurality of packet data convergence protocol (PDCP) packets, wherein each PDCP packet in the plurality of PDCP packets includes a set of OC symbols;
• apply a forward error correction (FEC) decoding to the set of OC blocks;
• and
• reconstruct the PDU set from the set of OC blocks based on the FEC decoding.
