DEMODULATION REFERENCE SIGNAL SHARING ACROSS USER EQUIPMENTS (UES) SUPPORTING OVER THE AIR DIGITAL PRE-DISTORTION - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240276403 titled 'DEMODULATION REFERENCE SIGNAL SHARING ACROSS USER EQUIPMENTS (UES) SUPPORTING OVER THE AIR DIGITAL PRE-DISTORTION
The patent application describes methods, systems, and devices for wireless communications, focusing on demodulation reference signal sharing across user equipments (UEs) supporting over the air (OTA) digital pre-distortion (DPD).
- Improved techniques for demodulation reference signal (DMRS) sharing across UEs supporting OTA DPD are introduced.
- A network entity can share a full DMRS pattern with multiple frequency-division multiplexed (FD-MED) UEs.
- UEs can evaluate non-linear impairment by estimating non-linearity (NL) compensation function coefficients based on the shared DMRS pattern.
- UEs indicate their estimated NL compensation function coefficients to the network entity.
- The network entity applies an updated NL compensation function based on the coefficients from various UEs and transmits a downlink transmission accordingly.
Potential Applications: - Enhanced wireless communication systems - Improved signal quality in OTA DPD supported networks
Problems Solved: - Addressing non-linear impairments in wireless communications - Optimizing demodulation reference signal sharing across UEs
Benefits: - Enhanced signal quality - Improved network efficiency - Better overall user experience
Commercial Applications: Title: "Enhanced Wireless Communication Systems for Improved Signal Quality" This technology can be utilized in telecommunications, IoT devices, and other wireless communication systems to enhance signal quality and network performance.
Questions about the technology: 1. How does the shared DMRS pattern improve non-linear impairment evaluation across UEs? 2. What are the key advantages of using OTA DPD in wireless communications?
Original Abstract Submitted
methods, systems, and devices for wireless communications are described. the described techniques relate to improved methods, systems, devices, and apparatuses that support demodulation reference signal sharing across user equipments (ues) supporting over the air (ota) digital pre-distortion (dpd). for example, the described techniques provide for demodulation reference signal (dmrs) sharing across ues supporting ota dpd. a network entity may share a full dmrs pattern with multiple frequency-division multiplexed (fdmed) ues. based on the shared dmrs pattern, the ues may evaluate the non-linear impairment by estimating non-linearity (nl) compensation function coefficients. each of the ues may indicate, to the network entity, their estimated nl compensation function coefficients. the network entity may apply an updated nl compensation function based on the nl compensation function coefficients from the various ues and transmit a downlink transmission according to the updated nl compensation function.
