Wireless communications based on rateless codes and layered modulation

A method for wireless communication at a receiving device, comprising:

• receiving, from a transmitting device, sets of coded symbols, each of the sets of coded symbols generated based at least in part on one or more corresponding sets of binary symbols;
• generating, for each of the sets of coded symbols, the one or more sets of binary symbols corresponding to the set of coded symbols to obtain a plurality of sets of binary symbols;
• decoding sets of binary symbols within the plurality of sets of binary symbols to obtain encoded packets;
• determining that a quantity of the encoded packets exceeds a threshold based at least on the generating;
• and
• decoding the encoded packets to obtain corresponding source packets comprising information for the receiving device, the decoding based at least in part on the quantity of the encoded packets exceeding the threshold.

An apparatus for wireless communication, comprising:

• a processor of a transmitting device;
• memory coupled with the processor, the memory and the processor configured to:
• generate, using a rateless code, encoded packets based at least in part on source packets comprising information for a receiving device;
• generate sets of binary symbols based at least in part on the encoded packets;
• select groups of sets of binary symbols, each of the groups comprising one or more of the sets of binary symbols;
• generate a respective set of coded symbols for each of the groups, the respective set of coded symbols for a group based at least in part on the one or more sets of binary symbols included in the group;
• and
• transmit, to the receiving device, a plurality of sets of coded symbols based at least in part on the generated respective sets of coded symbols.
