1. A method for wireless communication at a first device, comprising:
identifying a set of information packets for transmission to one or more receiving devices, each packet of the set of information packets for transmission in a respective transmission instance;
identifying two or more information subpackets of each packet of the set of information packets;
encoding a plurality of information subpackets from two or more different information packets according to a set of coding parameters to obtain a set of parity subpackets, wherein the encoding comprises:
mapping the plurality of information subpackets into K rows and X columns of a coding table, wherein each column of the X columns corresponds to a transmission instance and each row of the K rows corresponds to one information subpacket; and
generating the set of parity subpackets based at least in part on a determined relationship between respective parity subpackets of the set of parity subpackets and two or more entries of the coding table, wherein a first parity subpacket of the set of parity subpackets is based at least in part on a first information subpacket of a first information packet that is associated with a first transmission instance and a second information subpacket of a second information packet that is associated with a second transmission instance in accordance with the coding table, and wherein each information packet has a plurality of subpackets that each have an associated index value within the associated information packet, and the first information subpacket and the second information subpacket have different index values within the respective first information packet and second information packet; and
transmitting, to the one or more receiving devices, the first information packet in the first transmission instance, the second information packet in the second transmission instance, and the first parity subpacket in a third transmission instance.
