DMRS WITH DYNAMIC AND CONTROLLABLE PAPR PROPERTIES - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240129172 titled 'DMRS WITH DYNAMIC AND CONTROLLABLE PAPR PROPERTIES

Simplified Explanation

The patent application describes aspects related to the generation and transmission of MDMRs (Modulation Dependent Reference Signals) in DFT-S-OFDM and CP-OFDM waveforms. These MDMRs allow for matching the nonlinear model impact or properties between DMRS (Demodulation Reference Signals) and data in the waveforms, improving communication performance.

• MDMRs are generated from DMRS and have a PAPR (Peak-to-Average Power Ratio) distribution matching the signal including data in an uplink channel.
• The target PAPR of the MDMRs is based on the modulation scheme of the data, allowing for better performance.
• The MDMRs can compensate for any EVM (Error Vector Magnitude) that may occur due to PAPR reduction by a nonlinear operator of the UE (User Equipment), leading to improved communication performance.

Original Abstract Submitted

aspects are provided for generation and transmission of mdmrs which allow matching of nonlinear model impact or properties between dmrs and data in dft-s-ofdm waveforms as well as cp-ofdm waveforms. a ue transmits, to a network entity, an mdmrs generated from a dmrs. the mdmrs has a papr distribution matching a papr distribution of a signal including data in an uplink channel. a target papr of the mdmrs is based on a modulation scheme of the data. the ue also transmits the data in the uplink channel, where the uplink channel includes a pucch or a pusch. as a result of the ability of mdmrs to match the nonlinear impact of dmrs and pusch or pucch, the network entity may compensate for any evm that may occur as a result of papr reduction by a nonlinear operator of the ue, and communication performance may thereby be improved.
