1. A method, comprising:
sending wireless data to a receiver node, wherein the wireless data includes a plurality of codewords of quantity N;
receiving feedback from the receiver node that identifies a subset of the wireless data that the receiver node failed to receive correctly and that includes a token value as a label for the subset of the wireless data as a group, wherein the feedback identifies, using not more than M bits, a subset of the plurality of codewords as the subset of the wireless data that the receiver node failed to receive correctly and wherein M<N;
constructing retransmission wireless data that includes the subset of the wireless data and the token value; and
sending the retransmission wireless data to the receiver node.
