Techniques and equipment for multiplexing schemes for millimeter-wave downlink single-carrier waveforms

摘要

Some aspects of the disclosure generally relate to wireless communication. More specifically, aspects of the present disclosure provide a multiplexing scheme that may be suitable for single carrier waveforms. For example, some techniques and devices described herein allow multiplexing of multiple different data streams without compromising the single carrier characteristics of the waveform. As an addition or alternative, some techniques and devices described herein may provide non-uniform error protection, unequal bandwidth allocation, etc. as part of the multiplexing scheme. Examples of multiplexing schemes described herein include in-phase / quadrature (I / Q) multiplexing, superimposed quadrature amplitude modulation (QAM) based at least in part on layered bit mapping, and polarization partitioning of QAM with superimposed coding. Includes multiplexing and frequency division multiplexing using UE-specific beams.
