Resource mapping for probabilistic amplitude shaping

Abstract

Methods, systems, and devices for wireless communications are described. A wireless device may generate a first set of shaped symbols using a first distribution matcher corresponding to a first frequency subband, and a second set of shaped symbols using a second distribution matcher corresponding to a second frequency subband. The wireless device may segment the first set of shaped symbols into a first set of subblocks and may segment the second set of shaped symbols into a second set of subblocks. The wireless device may concatenate one or more subblocks from the first set of subblocks with one or more subblocks from the second set of subblocks. The wireless device may map the set of concatenated shaped symbols to a set of resources according to a frequency-first, time-second ordering. The wireless device may transmit the set of concatenated shaped symbols via the set of resources based on the mapping.
