DEMODULATION REFERENCE SIGNAL BASED CHANNEL ESTIMATION FOR ADJUSTING OR STOPPING RETRANSMISSION - A simplified explanation of the abstract
This abstract first appeared for US patent application 18185769 titled 'DEMODULATION REFERENCE SIGNAL BASED CHANNEL ESTIMATION FOR ADJUSTING OR STOPPING RETRANSMISSION
Simplified Explanation: The patent application describes a method for channel estimation using a demodulation reference signal (DMRS) to adjust or stop retransmissions in wireless communication systems.
- Receiving a transmission with DMRS via a downlink channel.
- Estimating channel quality based on the DMRS.
- Transmitting channel quality data and hybrid automatic repeat request data via an uplink channel.
Key Features and Innovation:
- Utilizes DMRS for channel estimation in wireless communication.
- Enables adjustment or stopping of retransmissions based on estimated channel quality.
- Improves overall system efficiency and reliability.
Potential Applications:
- 5G and beyond wireless communication systems.
- Internet of Things (IoT) devices.
- Mobile networks and cellular communication.
Problems Solved:
- Inaccurate channel estimation leading to inefficient retransmissions.
- Lack of reliable methods for adjusting transmission parameters in real-time.
Benefits:
- Enhanced system performance and reliability.
- Reduced retransmission overhead.
- Improved user experience in wireless communication.
Commercial Applications: Wireless network equipment manufacturers can integrate this technology to enhance the efficiency and reliability of their products, leading to improved user satisfaction and potentially gaining a competitive edge in the market.
Questions about DMRS-based Channel Estimation: 1. How does DMRS improve channel estimation accuracy in wireless communication systems? 2. What are the potential drawbacks or limitations of using DMRS for channel estimation in practical applications?
Original Abstract Submitted
Demodulation reference signal (DMRS) based channel estimation, e.g., for adjusting and/or stopping retransmissions, is described herein. A method as described herein can include receiving, by a device comprising a processor, a first transmission that is transmitted to the device by network equipment via a downlink channel, wherein the first transmission comprises a DMRS; estimating, by the device, a channel quality associated with the downlink channel based on the DMRS, resulting in an estimated channel quality; and transmitting, by the device to the network equipment via an uplink channel, a second transmission, the second transmission comprising channel quality data indicative of the estimated channel quality and hybrid automatic repeat request data corresponding to the first transmission.
