Systems and Methods for Phase Noise Tracking Reference Signal Sequence Generation Using Demodulation Reference Signals - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240291701 titled 'Systems and Methods for Phase Noise Tracking Reference Signal Sequence Generation Using Demodulation Reference Signals
Simplified Explanation:
The patent application describes user equipment for a cellular network that can efficiently transmit data using a demodulation reference signal (DMRS) and a positioning reference signal (PNT-RS).
- User equipment includes a transceiver, processor, and memory.
- The equipment determines a mapping from DMRS to PNT-RS for data transmission.
- A DMRS resulting signal is generated from a subset of DMRS for a resource element in a subcarrier.
- The DMRS resulting signal is copied to a second resource element assigned to the PNT-RS in the subcarrier.
- Data transmission is then transmitted using the DMRS resulting signal and the PNT-RS.
Key Features and Innovation:
- Efficient data transmission using DMRS and PNT-RS.
- Mapping from DMRS to PNT-RS for improved signal processing.
- Generation and copying of DMRS resulting signal for effective data transmission.
Potential Applications:
- Cellular networks
- Wireless communication systems
- Internet of Things (IoT) devices
Problems Solved:
- Enhances data transmission efficiency.
- Improves signal processing in cellular networks.
- Optimizes resource allocation for better network performance.
Benefits:
- Faster and more reliable data transmission.
- Enhanced signal processing capabilities.
- Improved overall network performance.
Commercial Applications:
- Telecommunications companies
- IoT device manufacturers
- Network equipment providers
Questions about the Technology:
1. How does the user equipment determine the mapping from DMRS to PNT-RS? 2. What are the advantages of using DMRS and PNT-RS for data transmission in a cellular network?
Original Abstract Submitted
a user equipment () is provided for use in a cellular network. the user equipment includes a transceiver (), a processor (), and a memory (). the user equipment () is configured to determine, for a data transmission, a mapping form a demodulation reference signal (dmrs) to a pnt-rs. a dmrs resulting signal is generated from a subset of dmrs for a first resource element in a subcarrier. the dmrs resulting signal is copied from the first resource element to a second resource element assigned to the pnt-rs in the subcarrier. the data transmission is transmitted using the dmrs resulting signal and the pnt-rs.
