Network coding and segmentation for packet data convergence protocol communications

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

• one or more memories;
• and
• one or more processors coupled to the one or more memories, the one or more processors individually or collectively configured to cause the receiving device to:
• receive a plurality of radio link control (RLC) protocol data units (PDUs);
• identify a difference between an RLC PDU size associated with the plurality of RLC PDUs and an outer coding symbol size associated with a plurality of outer coding symbols included in an outer coding block;
• and
• estimate a zero padding length for at least one of the outer coding block or the plurality of outer coding symbols in accordance with the difference between the RLC PDU size and the outer coding symbol size;
• and
• process the outer coding block or the plurality of outer coding symbols in accordance with the zero padding length to obtain a plurality of packet data convergence protocol (PDCP) packets.

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

• one or more memories;
• and
• one or more processors coupled to the one or more memories, the one or more processors individually or collectively configured to cause the transmitting device to:
• obtain a plurality of packet data convergence protocol (PDCP) packets;
• segment each PDCP packet of the plurality of PDCP packets into a plurality of outer coding symbols in accordance with an outer coding symbol size;
• generate an outer coding block in accordance with assembling the plurality of outer coding symbols;
• apply a forward error correction encoding to the outer coding block;
• and
• transmit the outer coding block in accordance with applying the forward error correction to the outer coding block.
