1. A method for wireless communication at a transmitting device, comprising:
receiving one or more service data units (SDUs) at a layer two (L2) layer of the transmitting device;
segmenting an SDU of the one or more SDUs into a set of protocol data units (PDUs) or a set of sub-PDUs at the L2 layer;
encoding, at the L2 layer and after segmenting the SDU into the set of PDUs or the set of sub-PDUs, the set of PDUs or the set of sub-PDUs according to one or more network coding parameters to obtain a set of encoded PDUs or a set of encoded sub-PDUs, the one or more network coding parameters comprising a rateless code;
generating, for the set of encoded PDUs or the set of encoded sub-PDUs, at least one corresponding PDU header; and
outputting each encoded PDU in the set of encoded PDUs or each encoded sub-PDU in the set of encoded sub-PDUs and the at least one corresponding PDU header from the L2 layer to a lower layer of the transmitting device for transmission to one or more receiving devices via a bearer.
