CHANNEL MEASUREMENT METHOD AND COMMUNICATIONS APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18155205 titled 'CHANNEL MEASUREMENT METHOD AND COMMUNICATIONS APPARATUS
Simplified Explanation
The patent application describes a method and apparatus for measuring the channel in a communication system. Here are the key points:
- The method involves a terminal device receiving precoded reference signals from a network device.
- The precoded reference signals are obtained by precoding reference signals based on K angle vectors.
- The terminal device generates and sends first indication information to the network device.
- The first indication information indicates P weighting coefficients corresponding to P angle-delay pairs.
- The P weighting coefficients are determined based on the precoded reference signals.
- Each of the P angle-delay pairs consists of one angle vector and one delay vector corresponding to the angle vector.
- The delay vector corresponding to each angle vector is preconfigured.
- The angle vector and delay vector are obtained through uplink channel measurement.
- The P angle-delay pairs and weighting coefficients are used to determine a precoding matrix.
Potential applications of this technology:
- Wireless communication systems
- Cellular networks
- Internet of Things (IoT) devices
- 5G and beyond networks
Problems solved by this technology:
- Efficient channel measurement in communication systems
- Precise determination of precoding matrix
- Optimization of wireless communication performance
Benefits of this technology:
- Improved signal quality and reliability
- Enhanced data transmission rates
- Reduced interference and latency in communication systems
- Increased capacity and coverage of wireless networks
