SYSTEMS AND METHODS FOR PDSCH BASED CSI MEASUREMENT - A simplified explanation of the abstract

This abstract first appeared for US patent application 18476530 titled 'SYSTEMS AND METHODS FOR PDSCH BASED CSI MEASUREMENT

Simplified Explanation

- Systems and methods for measuring channel state information (CSI) based on demodulating a reference signal for a physical downlink shared channel (PDSCH) transmission. - A user equipment (UE) can determine the demodulation reference signal (DMRS) for the PDSCH transmission with frequency hopping. - The UE measures the DMRS for the PDSCH transmission to determine a CSI measurement. - The UE reports the CSI measurement to a base station.

Potential Applications

This technology can be applied in: - 5G and beyond wireless communication systems - Internet of Things (IoT) devices - Autonomous vehicles - Smart city infrastructure

Problems Solved

- Efficient measurement of channel state information - Enhanced communication reliability and performance - Improved resource allocation in wireless networks

Benefits

- Increased data transmission efficiency - Better signal quality and coverage - Enhanced network capacity and throughput

Original Abstract Submitted

Systems and methods provide channel state information (CSI) measurement based on measuring a demodulation reference signal (DMRS) for a physical downlink shared channel (PDSCH) transmission. A UE may determine the DMRS for the PDSCH transmission with frequency hopping, and measure the DMRS for the PDSCH transmission to determine a CSI measurement. The UE may then report the CSI measurement to a base station.
