DMRS WITH DYNAMIC AND CONTROLLABLE PAPR PROPERTIES
Abstract:
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.
