Methods and Devices for Channel Estimation - A simplified explanation of the abstract
This abstract first appeared for US patent application 18090770 titled 'Methods and Devices for Channel Estimation
Simplified Explanation
The present disclosure describes a method for channel estimation in a network device. The method involves the following steps:
- Transmitting an instruction to a terminal device to precode a number of DeModulation Reference Signals (DMRSs) using a number of linearly independent precoders.
- Receiving the precoded DMRSs from the terminal device.
- Estimating an equivalent channel associated with the uplink channel from the terminal device to the network device based on the received precoded DMRSs.
- Determining the uplink channel from the estimated equivalent channel based on the precoders.
Potential applications of this technology:
- Wireless communication systems
- Cellular networks
- Internet of Things (IoT) devices
- Satellite communication systems
Problems solved by this technology:
- Accurate channel estimation in wireless communication systems
- Efficient utilization of resources in cellular networks
- Improved performance and reliability of IoT devices
- Enhanced signal quality in satellite communication systems
Benefits of this technology:
- Improved signal quality and reliability in wireless communication systems
- Increased capacity and throughput in cellular networks
- Enhanced performance and energy efficiency of IoT devices
- Better communication and connectivity in satellite communication systems
Original Abstract Submitted
The present disclosure provides a method () in a network device for channel estimation. The method () includes: transmitting () to a terminal device an instruction to precode each of a number, L, of DeModulation Reference Signals, DMRSs, using a number, N, of linearly independent precoders, respectively; receiving () from the terminal device L*N precoded DMRSs; estimating () an equivalent channel associated with an uplink channel from the terminal device to the network device based on one or more of the L*N precoded DMRSs; and determining () the uplink channel from the equivalent channel based on the N precoders.
