Method for Peak to Average Power Reduction of DM-RS Signals - A simplified explanation of the abstract
This abstract first appeared for US patent application 18412895 titled 'Method for Peak to Average Power Reduction of DM-RS Signals
Simplified Explanation
The abstract describes a patent application for a user equipment (UE) configured to enhance Demodulation Reference Signals (DM-RS) to reduce the Peak-to-Average Power Ratio (PAPR) to the same level as data symbols. The UE obtains an initialization value based on parameters and maps it to Code Division Multiplexing (CDM) groups for generating demodulation sequences.
- The UE is configured to enhance Demodulation Reference Signals (DM-RS) to reduce the Peak-to-Average Power Ratio (PAPR) to the same level as data symbols.
- The UE obtains an initialization value based on parameters such as cell ID, scrambling code ID, and a second parameter.
- The initialization value is mapped to either a first or second Code Division Multiplexing (CDM) group based on the scrambling code ID.
- The mapping associates the initialization value with the CDM group for generating demodulation sequences.

Original Abstract Submitted
A user equipment (UE) is configured to enhance Demodulation Reference Signals (DM-RS) in order to reduce the Peak-to-Average Power Ratio (PAPR) to the same level as for data symbols. To accomplish this function, the UE obtains a first initialization value that is calculated based on one of a first parameter (e.g., cell ID) and a second parameter and a scrambling code ID. The UE then maps the first initialization value to either a first Code Division Multiplexing (CDM) group or a second CDM group based on the scrambling code ID. The mapping associates the first initialization value with the first or second CDM group such that the initialization value is used when generating a demodulation sequence for that CDM group.
