1. A method, comprising:
determining a precoder for a set of modulation symbols, the precoder comprising a plurality of codewords and configured to reduce an ensemble interference and a pairwise interference for the plurality of codewords;
precoding the set of modulation symbols based on the precoder;
in response to the precoding, mapping the set of modulation symbols to a set of resources for a transmission layer, wherein a number of modulation symbols of the set of modulation symbols is greater than a number of resources in the set of resources;
generating a non-orthogonal multiplexed channel for the resources by overloading the set of modulation symbols at a transmission rate that is greater than a Nyquist rate; and
transmitting an indication of the precoder and the set of resources.
