Abstract

Apparatuses, methods, and systems are disclosed for precoding wireless communications. An apparatus includes a processor and a memory coupled with the processor. The memory includes instructions that are executable by the processor to cause the apparatus to precode a set of symbols over a set of resources using a transform precoder that constrains a search space of codewords to a unit hypersphere such that the transform precoder comprises a spherical codebook having an angular threshold distance between codewords and to combine the precoded symbols in a redundant manner such that multiple parts of precoded symbols are used to protect against loss of the set of symbols.
