CHANNEL STATE INFORMATION FEEDBACK METHOD AND APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240129092 titled 'CHANNEL STATE INFORMATION FEEDBACK METHOD AND APPARATUS
Simplified Explanation
The abstract describes a method and apparatus for channel state information (CSI) feedback in a communication system.
- Terminal device receives a CSI reference signal from a network device and performs channel sounding based on it.
- CSI is fed back to the network device using a first codebook determined based on various channel representations.
- The first codebook is based on transmit-end space-domain and frequency-domain vectors, receive-end space-domain and time-domain vectors, or a combination of these vectors.
Potential Applications
This technology can be applied in:
- Wireless communication systems
- 5G and beyond networks
- MIMO systems
Problems Solved
- Efficient feedback of channel state information
- Improved communication system performance
- Enhanced signal processing techniques
Benefits
- Enhanced signal quality
- Increased data transmission rates
- Better resource allocation
Potential Commercial Applications
- Telecommunication companies
- Network equipment manufacturers
- IoT device manufacturers
Possible Prior Art
One possible prior art for this technology could be the use of codebooks for channel state information feedback in previous communication systems.

The abstract does not provide information on the potential impact of this technology on network latency.
Are there any limitations to the number of channel representations that can be used in the codebook?
The abstract does not mention any limitations on the number of channel representations that can be used in the codebook.
Original Abstract Submitted
a channel state information (csi) feedback method and apparatus. a terminal device receives a channel state information reference signal (csi-rs) from a network device, and performs channel sounding based on the csi-rs. the terminal device feeds back csi to the network device based on a first codebook, wherein the first codebook is determined based on one or more transmit-end space-domain and frequency-domain column vectors and one or more receive-end space-domain and time-domain column vectors that represent a channel alternatively, the first codebook is determined based on the one or more transmit-end space-domain and frequency-domain column vectors and one or more time-domain column vectors that represent the channel.
